Product Details

Prepare to be blown away - this watch is Sinn's crowning achievement and features a movement so advanced that only a very small number are built each month.

As we have traveled the country showing the Sinn Collection through our Road Shows, the Sinn TESTAF Certified Professional Pilot's Series has stood out in every city.


Lothar Schmidt, Sinn's CEO and owner had long been disturbed by a lack of technical standards for defining a "pilot's watch". As an engineer, Mr. Schmidt was fluent in standards for diver's watches, anti-magnetic watches and the many other technological standards used to manufacture watches.

A widely used reference for standards is DIN, or the Deutsches Institut fr Normung (German Institute for Standardization). Oddly, he discovered there were no DIN standards to cover pilot's watches where such standards exist for example for diver's watches.

Many watch brands classify their watches as "professional pilot's watches", but Mr. Schmidt knew that this was a hollow phrase that had absolutely no substance behind it.

He set out on a journey to encourage the independent development of a set of standards to which a watch must conform to be classified a certified pilots watch, and TESTAF was born.

Mr. Schmidt recently spoke with us and indicated that DIN will adopt the standards set by TESTAF for professional pilots watches. He expects this action to be taken in the next few years at which time there will no longer be confusion about what is a true certified professional pilots watch.

The Sinn EZM 10 TESTAF DIAPAL was tested and certified to the "Technical Standard for Pilot's Watches" (TESTAF) by the Aachen University of Applied Sciences.

This establishes its suitability for professional use as a pilot's watch, and includes a certificate and the "TESTAF" quality seal on the dial.

Summary of Technologies

The range of technologies also includes Sinn's Dry Hold technology for greater functional reliability and freedom from fogging and overall functional reliability at temperatures between - 45 C and + 80 C.

Take a look at these specs, and we think you will agree this watch sets a new standard for pilot's watches:
  • Tested and certified to the Technical Standard for Pilot's Watches (TESTAF) by the Aachen University of Applied Sciences
  • Sinn SZ-01 calibre
  • Centrally mounted elapsed chronograph hand
  • Case made in-house of Tegimented titanium by Sinn's case manufacture in Glashutte, Germany
  • Dehumidifying technology enhances functional reliability and freedom from fogging
  • Functionally reliable from - 45 C up to + 80 C
  • Captive pilot's bezel with minute ratcheting
  • Sapphire crystal glass
  • Water resistant to 200 meters
  • Low pressure resistant
  • DIAPAL oil free escapement with nano-technology
  • Flush chronograph pusher mounts
  • Dual color SuperLuminova
  • 5 year limited manufacturer's warranty

Additional Background

The Sinn EZM 10 TESTAF is the first watch worldwide that been tested and certified to the new Technical Standard for Pilot's Watches (TESTAF). Each watch will be shipped with a special signed certificate indicating that this watch bears a serial number which is within the range of those watches approved by TESTAF.

However, Sinn didn't want to make just a pilot's watch. They also wanted to make the most technologically advanced Mission Timer (EZM) to date, by including an extensive range of additional features.

To start, at the heart of this chronograph is the all new Sinn SZ-01 movement, which features a center-mounted 60 second stopwatch hand. 

This special technical feature yields two benefits: first, 60 minutes are now counted in one sweep of the hand instead of the usual 30 minutes, and second, the minute stop scale covers the entire diameter of the dial meaning that the measured times can be read off immediately. 

Additionally, the chronograph hands are luminous, and thus perfectly visible even in the dark. This function is complemented by an all-new minute-ratcheting sapphire pilot's bezel, which allows for the numerals indices and main maker to all be lumed.

Tegimented Titanium - A First

Also in use for the first time is a fully-tegimented case made entirely of high-strength titanium at Sinn's case making manufacture in Glashutte, Germany. The Tegiment process, Sinn's patented case-hardening technology, was previously available only to those watches which featured a stainless steel case, which is quite heavy in comparison to titanium. 

As a large watch, the Sinn EZM 10 TESTAF would need to be light enough for daily wear, yet also tough enough to resist scratching in an often cramped and busy cockpit environment, and thus the process to Tegiment titanium was invented.

Th EZM 10 and EZM 9 are the only such watches in Sinn's current production to feature Tegimented titanium.

The watch is water resistant to 200 meters, and features a black calf-leather strap with water-resistant backing and orange stitching. 

DIAPAL Escapement

This new watch features the very latest construction of Sinn's patented DIAPAL oil free escapement.

Beginning in 1995, Sinn began work to create an oil free escapement. With any mechanical watch movement, the aging of oil, especially in the escapement can create long term problems for that movement. Additionally, as movement oil ages, required service intervals become more frequent.

Sinn's early analysis to this problem provided a quick solution (at least in theory) - if you don’t use oil, it can’t age. The process began by exchanging the ruby escapements for diamonds (the word "DIAPAL” derives from the German name for diamond escapements, "Diamantpaletten”) in order to achieve the desired effect. The designation stuck, even though today Sinn works with solutions taken from advanced nanotechnology rather than diamonds.

The result is a movement that proves so reliable that Sinn offers an unprecedented five year warranty on their DIAPAL watches.

Great choices to add to this watch:

WatchBuys is the official and authorized North American distributor and importer for Sinn watches.

When you purchase your new Sinn watch from WatchBuys, you'll not only get a finely engineered timepiece with excellent value for money, you'll also benefit from the WatchBuys Sinn Advantage.

WatchBuys Advantage #1

Because we are the official and authorized North American Sinn distributor and importer, your name and watch serial number will be automatically registered in our database for a Sinn manufacturer's limited warranty which we pass through.

This means that should your watch require service during the Sinn manufacturer's limited warranty period, service will be provided by Sinn in Germany when you return your watch to them. This Sinn manufacturer's limited warranty is transferable to subsequent owners as allowed by Sinn.

You are responsible for paying the shipping charges to Sinn, and all repairs that Sinn approves under its warranty are at no charge. Sinn will also pay the return shipping charges to the address you specify.

The Sinn manufacturer's limited warranty period is as follows:
  • Watches in the EZM Series: 3 years
  • Watches marked AR containing inert gas: 3 years
  • Watches in the DIAPAL Series: 5 years
  • All other Sinn models: 2 years

WatchBuys Advantage #2

As an added benefit to those who purchase Sinn watches from WatchBuys, you may choose to have your warranty repairs serviced through our US Sinn Authorized Service Center, RGM Watch Service located in Mount Joy, Pennsylvania. This added benefit saves our clients the time and effort of returning their watches to Germany for repair. This service is transferable to subsequent owners who purchase directly from the original registered owner.

Please note that you are responsible for paying shipping and insurance charges for sending your watch to RGM. Once they reach your watch in the service queue they will determine which repairs are covered under Sinn's warranty.

It is important to note that oil-filled quartz Sinn watches must be repaired in Germany (EZM 2, Hydro and UX series). If your watch meets one of these conditions and requires service under warranty, please click here for instructions on returning your watch to Sinn in Germany.

WatchBuys Advantage #3

Your watch will be repaired at no cost to you other than shipping charges to either Sinn or RGM during the warranty period. Sinn watches purchased through the "grey market" (non-authorized sources) may carry no warranty from Sinn. Sinn watches purchased through authorized overseas retailers are governed by the warranty policies of those dealers and/or Sinn, and typically must be sent to either the overseas dealer or Germany for repair.

WatchBuys Advantage #4

You'll be wearing your new Sinn watch soon after your order is placed since we stock Sinn watches and ship free using FedEx Air. Plus, since we are located in the United States, there are no "hidden charges" for shipments to US residents as is the case with most overseas dealers. Such charges can add up to 15% to the cost of your new watch, and include credit card surcharges, foreign exchange credit card bank fees, import duties and taxes, and custom's broker charges.

WatchBuys Advantage #5

WatchBuys offers a comprehensive return policy with no restocking fees to US residents. Overseas dealers, including those involved in the grey market, typically don't offer a return policy, and if they do, returning a watch under the policy is both complicated and expensive due to import/export and custom's requirements. Restocking fees are also common and may range up to 15%.

Sinn watches feature a number of cutting edge technologies, many of which are unique to Sinn. Please note that not all Sinn watches, including the watch on this page, use all of these Sinn technologies.

Among the more notable Sinn technologies are:

Tegimented Hardened Cases

Many Sinn watches are fitted with Tegimented cases produced in-house by Sinn's case making affiliated company in Glashutte, Germany.

Standard steel used by most watch companies has a hardness of between 200 and 240 HV (Hardness Vickers is a common scale used to measure material hardness). The Tegiment process produces a hardness of at least 1,200 Vickers which is five times harder than standard steel (and on some Sinn models up to nine times harder than standard steel).

The Tegiment process is not a coating consisting of a foreign material; instead the steel itself that has been hardened using a special engineering process that creates a hardened barrier. The base material is a type of stainless steel also used for surgical implants, and the stainless steel resistance to corrosion is further improved by the Tegiment hardening process.

The primary advantages to a Tegimented case are extreme resistance to scratches and other case abrasions, as well as increased resistance to corrosion.

Please note that certain Sinn watches are fully Tegimented (case, bezel) while others are Tegimented only on the bezel. Use the links below to view both categories.

  • View Sinn watches with fully Tegimented cases.

  • View Sinn watches with Tegimented bezels only.

Dehumidification Technology

A number of Sinn models feature cases filled with inert gas. Sinn has found that filling the case with inert gas can help prevent the introduction of moisture and humidity to the case, as well as provide a more stable environment for the oils that lubricate the movement.

The proper care of any mechanical watch movement mandates that these oils maintain both their viscosity and lubrication properties.

  • View Sinn watches with dehumidification technology.

Copper Sulphate Capsules

A number Sinn models use one or more copper sulphate capsules to absorb humidity trapped inside the case. Over time these capsules will gradually turn dark blue indicating that humidity has been absorbed.

The primary benefit to these copper sulphate capsules is a more dry and stable environment for both the movement and the lubricating oils. Together with Sinn's inert gas treatment these capsules form the basis of Sinn's Dry Hold Technology.

This technology not only provides a more stable environment for the movement, but also prevents fogging of the crystal when going from hot to cold environments or from humid to non-humid conditions (such air conditioned buildings).

  • View Sinn watches with copper sulphate capsules.

Extreme Antimagnetic Protection

Magnetism can cause dramatic swings in the timekeeping of a mechanical watch movement. People are often exposed to magnetic fields without even being aware - frequent high altitude flying, metal detectors, audio and video equipment, medical equipment and computer equipment can all cause problems with magnetism.

Many Sinn watches offer extreme protection against magnetism up to 80,000 A/m. Sinn achieves these results using a number of different technologies, including special case and case back construction, soft iron components in the case and protective rings surrounding the movement.

  • View Sinn watches with extreme antimagnetic protection.

DIAPAL Oil Free Escapement

Sinn caused quite a stir when they first released their DIAPAL technology. Beginning in 1995, Sinn began work to create an oil free escapement. With any mechanical watch movement, the aging of oil, especially in the escapement can create long term problems for that movement. Additionally, as movement oil ages, required service intervals become more frequent.

Sinn's early analysis to this problem provided a quick solution (at least in theory) - if you don't use oil, it can't age. The process began by exchanging the ruby escapements for diamonds (the word "DIAPAL" derives from the German name for diamond escapements) in order to achieve the desired effect. The designation stuck, even though today Sinn works with solutions taken from advanced nanotechnology rather than diamonds.

The result is a movement that proves so reliable that Sinn offers an unprecedented five year warranty on their DIAPAL watches.

  • View Sinn watches featuring the DIAPAL oil free escapement.

Hydro Oil Filled Technology

Sinn has developed a technology termed "Hydro" in which the entire watch case is filled with oil. Watches using this technology are based on quartz rather than mechanical movements.

By using this type of movement, Sinn is able to fill the watch with oil, which has the joint affect of greatly enhancing the readability of the dial and time from any angle (including under water), and increasing the water resistance of the watch even at great depths.

  • View Sinn watches with Hydro Oil Filled technology.

Submarine Steel

Sinn has created a line of watches featuring cases made from German submarine steel (the U Series). The steel was procured by Sinn from a steel supplier to Emden GmbH, one of Germany's North Sea shipbuilding yards who construct submarines from the very same steel.

Because of the special steel used from the submarine steelmanufacturer, the case resists the effects of exposure to salt waterand salt water environments.

These cases are produced in-house by Sinn's case making affiliated company in Glashutte, Germany.

This special steel is also amagnetic which means that is does not have magnetic properties and cannot itself become magnetized. The watch movement itself is protected from magnetic fields up to 4,800 A/m.

  • View Sinn watches built from German submarine steel.

EZM Mission Timers

Sinn is a partner for manufacturing watches for the German Special Forces, including SWAT, Customs, FBI, helicopter police, GSG9 and other units.

Beginning with the now highly collectible (and valuable) Sinn EZM 1, Sinn has grown this collection to some of the most durable and highly functional watches made and they remain among the most popular in the collection.

Sinn EZM 10 - A pilot's perspective

"Sinn EZM 10 - A pilot's perspective"

Verified Owner Comments: I have been wearing the EZM 10 for a few months now. I am a 747 Captain predominantly flying long haul international legs. My eyes are not what they used to be so, the legibility of the dial is a big plus. The center minute chronograph hand is easy to read at a glance. The color coordination of the Chrono hands are well thought out and useful. The lumed bezel is superb in both form and function as are the flush pushers. The crown is precise and feels solid as does everything about the watch. The titanium case is comfortable and is sized proportionally for its purpose as a true flying instrument. The watch encompasses all of Sinn's tool watch technology while also being pleasing to look at. I like the fact that they provided a 24 hour AM/PM sub dial since I cross the dateline frequently. This makes changing the quick set date easier. I am not hard on my watches these days, but the Tegimented case eases any worry about damaging the watch due to the inevitable bumps and dings that hap... - more details

EZM10 is a winner!

"EZM10 is a winner!"

Verified Owner Comments: I have admired Sinn watches for a long time and finally bought one. Before deciding on the EZM 10 I was considering a Damasko DC86. Since I already have 2 Damaskos it made sense to add a Sinn to the collection. The EZM 10 showcases most all of Sinn's cool technologies and is why I was drawn to it.

The fit and finish and perceived quality of this watch are through the roof! I've been wearing it non-stop since I received it a month ago. It's very comfortable and has great wrist presence. I am extremely happy with it!

The overall buying experience from Watchbuys was excellent. Rob and team are very professional and quickly answered questions and provided excellent communication from the time I placed my order until the stunning EZM 10 was on my wrist!

I'm already looking forward to my next Watchbuys purchase and would not hesitate to recommend them to anyone!

Fantastic watch and great CS

"Fantastic watch and great CS"

Verified Owner Comments: I purchased this watch a few weeks ago before the recent price increase. I was quoted 45days because WB was waiting for the next orders to arrive. The watch arrived in less than half that time (FedEx Overnight). Unfortunately the chrono functions weren’t working correctly. It was a Saturday and I wanted to make sure they were notified within the 3 calendar day inspection requirement, so I called and left a VM that night. On Sunday I followed up with an email and a few videos to help describe the issue. Literally within a few minutes, Jon from WB replied with an apology and a prepaid 2-Day FedEx label....on Sunday! On top of that, knowing how quickly the EZM10 sells out, I checked the website the day my return was scheduled to arrive and they were sold out. I figured I had another wait until a new batch came in. I resisted my urge to immediately call WB and trusted they’d call me when they confirmed my findings. Sure enough, I received an email Thursday morning to confirm that I’d b... - more details

Chronograph for outdoor recreation

"Chronograph for outdoor recreation"

Verified Owner Comments: Delighted with the EZM10. It is my first chronograph so it took some time to get used to the busy dial, but the more time I spend with it, the more I really appreciate it. The engineering that goes into this piece is truly impressive. My wrist is 6.5 inches (16.5 cm) so this is the very upper end of watch sizes I would consider wearing (I like 38-40mm cases). It honestly does not feel as large as I expected. I primarily wear it during outdoor activities (hiking, running, biking, etc.), not as a general everyday watch, so the size is subordinate to function. I know this use is different than the intended pilot demographic, but a lot of the features that make this watch so good for pilots translate well to outdoor recreation. The Sinn leather and rubber straps are fantastic quality. I generally wear on the rubber since it is being exposed to water/sweat frequently but the leather is nice to mix it up. I have tried the EZM 10 on a Nato, and it was a poor match due to the large size/we... - more details

The whole package

"The whole package"

Verified Owner Comments: I believe I’ve been dealing with these guys for at least 20 years, give or take a few . I can’t speak highly enough for their customer service. I receive answers to questions via email or chat almost instantaneously. Unbelievable in this time of ours.

As for the Sinn EZM 10 , the watch really speaks for itself. A highly technical chronograph that I’ve always looked at and finally pulled the trigger on obtaining. The sapphire covered bezel is a beautiful touch on this extremely legible albeit seemingly complicated dial.

Everything has its purpose and functions accurately . I’d put it up there with the best chronographs and pilot and diving look watches. The case is as tough as Sinns preceding reputation . An under-rated brand that seems under the radar save for those that know watches.

The Tool Watch

"The Tool Watch"

Verified Owner Comments: If you want the top of the line Sinn watch with all the cool features that make a Sinn a Sinn, then this is the watch to buy. The central seconds and minutes of the chronograph is so much easier to read than a standard chronograph lay out.

The EZM 10 is a great watch.

The EZM10 is an incredible watch

"The EZM10 is an incredible watch"

Verified Owner Comments: There are other chronographs, many more expensive, but there is nothing like the Sinn EZM10. The tegimented titanium finish is amazing. My watch has zero scratches after over a year of wear. The chrono pushers are positive action and flush. The EZM10 pushers are easier to operate and can’t be accidentally engaged.

The Lemania-like central seconds and minute hands makes the chrono super easy to read and the contrasts on the dial do the same for the time. The bezel won’t pop off and has a nurled titanium edge that makes it easy to turn with positive detent. I went with the titanium bracelet because I like the fitted look. The watch wears great even though its 44mm, partially because of the lightness of the titanium.

Some people say this watch is expensive ‘for a Sinn’. I look at it the other way, I think its cheaper and better engineered than any chrono that I shopped. I also own a Sinn 903.

Their watches are well made and the service at Watchbuys is great.

Give yourself a hand or two...

"Give yourself a hand or two..."

Verified Owner Comments: Mine arrived today but I’ve had the pleasure of flying with a friend this past month, he wanted to try my Exospace and offered his EZM-10 in return which he knew I’ve been eyeing. What an instrument this is! Just having the legendary SZ-01 on my wrist is fun but this EZM-10 is a serious, ultra-capable performer. Having the centrally mounted, highly visible orange stopwatch hands, seconds and minutes running on the full watch face means at a glance you really do know the time elapsed – many chronos claim this but I’ve used many and none do it this well. Oh beloved Breitling, IWC and Omega you'll be riding the winder while Sinn EZM-10 and I go fly. For some airshow pilots this is an instrument that could become the 7th in the six pack. Timing is so simple and precise that I use it in older warbirds and timed routines. Sinn sacrificed nothing in visual appeal to make this incredible instrument - I can't call it a watch, loaded with features and technology. The sapphire out to the beze... - more details

Outstanding Quality !!

"Outstanding Quality !!"

Verified Owner Comments: The Sinn EZM 10 is one winner, and really hits it out of the park! The chrono works flawlessly and is a pleasure to read and use. The watch case is not only light but very attractive. The leather strap is beautiful, very high quality and really keeps the watch secure on wrist. Although some might think the price is high, with all the technological features included in this watch, it's truly a bargain! Unlike alot of brands who add 40 or 50 per cent to the price and then discount them down to make you feel you are getting a bargain, Sinn prices their watches at a fair price to start. The lume on this watch is incredible. I charge it when I go to bed at 10 or 11, and at 7am it is still going strong. Watchbuys 3 day inspection period is a great asset in selling, and a real comfort in buying! I would expect they don't get any of these beauties back though, LOL. The staff at watchbuys are an encyclopedia of watch information and are more than happy to talk to you for as long as it takes... - more details

Plus it looks excellent and has a great fit.

An engineer was looking for a chrono...

"An engineer was looking for a chrono..."

Verified Owner Comments: I was looking for a mechanical chrono with both above average technical specs and a not too flashy style that i could wear to work without causing notice. Sinn watches fit that aesthetic well, but which one to pick? After a couple months of internet research, I finally settled on the EZM10 both for its looks and because it has most all of Sinn's technical goodies in one package. The Watchbuys staff gave prompt, professional replies to my questions and kept me informed on order progress. Although the initial estimate was a 4-5 week wait, I was pleasantly surprised to actually receive it about two weeks after ordering. I was a little worried the size might be too tall & wide for my 6.75-7 wrist, but after getting it out of the box and putting it on, I found the fit was just what I was looking for and knew right away it was a keeper. The lightweight titanium case offsets the 15.5mm height nicely and provides a natural, comfortable wear. The dial's font, colorway, and overall finis... - more details

Great watch

"Great watch"

Verified Owner Comments: I ordered this watch last Tuesday and received it in San Diego early Thursday morning (great shipping), This is a great watch (no complaints so far). I have been looking for a rugged chronograph that can get wet and just be an every day watch you don't have to worry about hitting something hard and scratching your nice watch. Watchbuys has great customer service. This is my first Sinn watch, but not my last. Thanks watchbuys!!

Maybe the best Sinn ever

"Maybe the best Sinn ever"

Verified Owner Comments: This is my 3rd Sinn. I think it's the best although I love my U1 and EZM13. This watch does it all and the lite weight and build quality are exemplary. The ceramic countdown bezel is fantastic and it's lured so even more useful. I also love the strap and won't change it.

Best Sinn Watch

"Best Sinn Watch"

Verified Owner Comments: Excellent watch.

Has almost all of Sinn technologies. Big but very light and comfortable to wear. Looks great on my 170cm wrist. There's a tiny chip under the sapphire bezel that reflects light, other than that excellent build quality. The chronograph has crisp pusher action. The bezel also has satisfying click with no play. The Chronissimo strap is high quality, durable and comfortable.

LOVE this watch!

A Very Impressive Watch

"A Very Impressive Watch"

Verified Owner Comments: First of all, I must mention the great customer service from Watchbuys. This was my first purchase, and I called immediately upon placing my order to understand the process. The customer service representative couldn't have been more helpful or courteous. All my questions were answered, and my Sinn EZM 10 was on its way to me.

It arrived just as expected. Packaging was well done, and the watch was set to the correct time within about 2 seconds - a nice touch.

The Sinn EZM 10 has exceeded my expectations. As advertised, it is a highly legible pilot's much so that I've received several comments on how striking it is. This is my first Sinn. The quality and attention to detail are outstanding. The long list of innovative technical features are's great to know they are there. The chronograph movement is extra special. The central 60 sec and min hands make it an extremely usable chronograph.!

Amazing Watch, Great Service

"Amazing Watch, Great Service"

Verified Owner Comments: The watch specifications speak for themselves. It's the pinnacle of Sinn's tek. I couldn't be more pleased with the fit, finish and function. I have 7.25 inch wrists and it disappears, largely because of the titanium construction. Service is fantastic.

I'm a repeat customer for good reason. The staff are really into watches and not simply selling for the sake of sales.



Verified Owner Comments: Reviews on the EZM 10 TESTAF abound online as well as perhaps some of the most comprehensive technical data on any timepiece. So rather than write a typical review encompassing features, benefits, design and value, I will focus on the specifics that concerned me pre-purchase. 1.Size and comfort. I typically wear larger watches including Panerai, IWC Big Pilot, Zenith, etc. The Sinn checks in at the larger end of the scale, and appears to have a bolder presence in photos. It wears very well. The lightweight Ti case coupled with the mat finish ensures a level of understatement and seems to point to the seriousness of this tool. The integrated chrono pushers contribute to containing the ‘footprint’ of the watch. Very well executed. 2.Strap. I was concerned that the strap with orange stitching would be a bit too much. Considering one of my favorite go-to watches is a Doxa Pro (orange dial), in hindsight this concern was unwarranted. The stitching perfectly matches the orange elements o... - more details

EZM 10 with bracelet

"EZM 10 with bracelet"

Verified Owner Comments: Great watch, highly functional and very understated (for a large titanium watch).

Perhaps the best tool watch on the market, and certainly the best priced. The titanium case and band are very scratch resistant, the sapphire bezel is highly readable and also scratch resistant, and the central minute hand makes this the most legible chrono available.

First purchase from WatchBuys

"First purchase from WatchBuys"

Verified Owner Comments: A perfect work watch.

As large as it is, it comes in at only 117 grams. That is as light as my Rolex GMT master which is less than 1/2 the size.

The best thing about the purchase was the great customer service and how easy it is to get a knowledgeable person on the phone before and after making the purchase.

This company Rocks!

Sinn EZM 10

"Sinn EZM 10"

Verified Owner Comments: It's been a pleasure doing business with WatchBuys - customer service is outstanding.

As for the watch, I like it a lot. Has the in your face look that got my attention. Plus the Sinn quality. Having said that, I do think that the watch is over priced. For that kind of money it should have included the bracelet. All and all I'm happy with the watch, it's all that you would expect from the Sinn line up.

My First Sinn

"My First Sinn"

Verified Owner Comments: This is one great looking watch!

It's imposing, but surprisingly light thanks to the Titanium construction. The black leather band with the orange stitching is very sturdy and makes this watch pop even more. The regular size for the wristband was too small, but WatchBuys had a long version readily available and that fit perfectly.

The Superwatch

"The Superwatch"

Verified Owner Comments: Sticker shock!  That's the first thing you'll feel when you encounter this timepiece. You'll realize that you're getting into Omega territory, and may even be tempted to go there. Don't go there! There is nothing else like it, and its well worth the price.  Why? This chronograph is the most legible, usable timer I have ever owned.  The centrally mounted orange second and minute hands make reading the chronograph as easy as telling the time. Moreover, everything on this watch is color coded; orange for chronograph, white for time. Make no mistake, this is a real chronograph, not just a sporty adornment you'll never use. It may look complicated, but it's really simple, and within a day it will feel like an extension of your mind.  The titanium case is perfectly tapered, and very light relative to the size of the watch, making it extremely comfortable and easy to wear.  Granted, with a watch like this, you'll know you have it on. But it feels great. The crown is e... - more details
