Product Details


We love this watch, and feel that Sinn got it right by listening to their clients.

Sinn's inspiration for the design of this watch is the historic Sinn NaBo clocks, long manufactured for use in cockpits as a navigational tool.  Even today Sinn continues to produce these clocks which are used in both civilian and military aircraft, as well as specialty cars.

This watch features "Tegiment" technology. 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 layer has a hardness of 1,200 Vickers which is up to five times harder than standard steel.

The Tegiment layer 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 even further improved by the Tegiment hardening process.

Next, this case offers magnetic field protection of up to 80,000 A/m, among the highest for any mechanical watch. The case back is nickel free offering protection to those with allergic reactions to this metal.

The case features a copper sulphate capsule which reacts with moisture to diffuse and absorb humidity in the watch.

And for those that don't encounter magnetic fields on a regular basis, it's just a great watch to wear every day.

Sand-blasted stainless steel case with solid back. Dial is matte black with Arabic numerals and offset date display at 4. The design and layout of this watch make it extremely easy to read in virtually all light conditions.

Sapphire crystal with luminous hands and hour markers. Watch is water resistant to 20 ATM. Bracelet is stainless steel which is fully Tegimented with folding clasp.

Other features include Sinn's Dehumidifcation Technology which uses inert gas to reduce humidity and to prevent the dial from fogging.

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 UPS 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%.

Learn more about our return policies.


WatchBuys Advantage #6

WatchBuys is pleased to accept payments through PayPal, debit and credit cards. We charge no surcharges to use credit or debit cards, and because we are based in the United States your US card is charged in US dollars with no conversion or exchange rate fees.

We also accept payments from PayPal and charge no surcharges.

Please note that to pay by credit card, debit card or PayPal your account and/or card must be issued by US or Canadian financial institution and billed to a confirmed US or Canadian address.

When you purchase your new Sinn watch from WatchBuys, you'll earn WatchPoint Rewards which accumulate and may be redeemed against future purchases.




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.

856 tegimented

"856 tegimented"

Verified Watch Owner Comments: This is my third Sinn watch purchase from Watchbuys, I still own a 104 and I sold a 556ir. The 856 is such a solid feeling watch, the first thing I noticed was the weight. It’s heavy, but also very comfortable on the wrist.

The 40mm diameter fits perfectly on my 7’ inch wrist. The tegimented grey color is beautiful as well, it almost looks like titanium. It’s my most legible watch and it really feels bombproof. So far it’s running close to perfect, -1 spd. If I could only keep one watch in my collection it would be this one.

Also, Watchbuys is great doing business with, very responsive and always nice on the phone.

Sinn 856 on bracelet

"Sinn 856 on bracelet"

Verified Watch Owner Comments: It was worth the year and a half wait! My only other watch was a Rolex Datejust that I wore for more than 20 years until I was no longer able to see the hands without reading glasses so that will be my basis of evaluation.

The Sinn 856 seems a bit thicker and heavier, but I did choose a larger sized model. I am able to tell the time on the Sinn without glasses in any conditions. The bracelet is very nice and I feel that the clasp is more secure than the Rolex. I feel that the Sinn is very accurate but I have only had it 3 weeks. The date is unusable for me but I would be fine if they left it off. I feel that this will be my last watch.

856A tegimented

"856A tegimented"

Verified Watch Owner Comments: Super legible, really scratch resistant, and — as someone who has had other watches become magnetized — the magnetic resistance adds peace of mind. This specimen is pretty accurate too: plus 7spd, with negligible positional error.

Wrist Companionship

"Wrist Companionship"

Verified Watch Owner Comments: I beat the hell out of my watches, and this one is no exception. The tegimented surfaces has a couple very small "dings” from smashing this bad boy agains rocks while backpacking.

It’s bullet proof. The dial is very clear and easy to read the time, paired with a anti reflective coated crystal is amazing. At night the lume is very bright and is still legible in the early morning hours.

Truly a beautiful timepiece that I will cherish for a lifetime.

Very nice

"Very nice"

Verified Watch Owner Comments: First, props to WatchBuys for great service. The one I wanted required replacing the leather bracelet with the steel one, which they did for me. All my questions were asked.

The watch itself is very good. Size is great, not too small, not too big for a 6 foot tall man with moderate thickness wrists. So far it's been quite accurate. It exudes quality without being too noticeable and loud. My only wish is for somewhat brighter lume. I can't see the numbers well by 5 am or so, although my eyesight is not that great so maybe it's just my eyes.

Overall, understated elegance of this watch works great for me.

Professional Tool Watch

"Professional Tool Watch"

Verified Watch Owner Comments: I bought the 856A for daily wear in my job as a pilot. It more than fits the bill great esthetics and exceptional build quality. Very pleased with the Watchbuy experience, I highly recommend them.

Great Purchase!

"Great Purchase!"

Verified Watch Owner Comments: My husband has been eying this watch for almost a year so I decided to surprise him with it. The watch itself is great, and again my husband did a lot of research on this so we knew what we were getting. He really loved the 856 over the 556.

The finish is really nice.

The best part about watch buys was customer service, I was hesitant to make such a large purchase on here but I will definitely use them again. They have excellent customer service and are incredibly helpful with any and all questions!

Love my new 856

"Love my new 856"

Verified Watch Owner Comments: Had my 856 for about 2 weeks now. It was easy to get the bracelet adjusted, runs well at just about +5/6 sec/day. I expect the tegiment treatment to keep the watch looking great for a long time and like the toned-down, utilitarian look of the watch.

The high contrast matte dial is easy to read in all light and the watch goes well in almost any situation.

Sinn 856

"Sinn 856"

Verified Watch Owner Comments: I recently purchased a Sinn 856 from WatchBuys, and I couldn't be happier.

The customer service at time of purchase and a follow-up phone call at time of shipping was very much appreciated. The watch is beautiful, and runs great.

I'm a very happy WatchBuys customer.

On the fence

"On the fence"

Verified Watch Owner Comments: First, let me say that Watchbuys was fantastic to work with. I've never experienced customer service to this level before. Outstanding!

As far as the watch is concerned, I'm still on the fence. First off, if you're concerned that the 40mm case might be a little small, then it probably will be. It's not noticeably small on my 7.25 inch wrist, but i think 41 or 42 would do better. So far, over the last eight days, it consistently has gained 6-7 seconds a day. Hopefully it will settle in eventually. The luminescence of the face is pretty much non existent. After most of the day out in the sunlight, it is unreadable at bed time. Lastly, the tegimented finish, while apparently very tough, is also very dark. Not unattractive, but certainly even darker than I was expecting. I'm totally willing to give it plenty of time to settle in and get used to it, but after the first week, I'm not totally sold on it.

Uniquely beautiful and useful

"Uniquely beautiful and useful"

Verified Watch Owner Comments: This is a great watch and I got great service. A fine addition to anyone's collection.

Good, But Not Great

"Good, But Not Great"

Verified Watch Owner Comments: After wearing my Sinn 856 every day for over a month, I have decided to issue a report card. Possible grades are A, B, C, D or F.

Accuracy (A-) Accuracy is very good. My watch gains 3-4 seconds per day.

Bracelet and clasp (C+) Expect the bracelet to rattle and do some occasional hair pulling. Sinn should study the Omega Seamaster bracelet and clasp and produce something similar. The Seamaster bracelet is superior in every way.

Design (A) Simple and classy. Well done.

Legibility (A) The 856 is easy to read in all conditions.

Wearing comfort (B) The large crown has sharp ridges that make setting the time very easy. Unfortunately, those ridges can cause some discomfort depending on the position of the watch on your wrist.

Overall grade (B) The 856 is a well made watch with some room for improvement in the bracelet.

Sinn 856 fully tegimented on bracelet

"Sinn 856 fully tegimented on bracelet"

Verified Watch Owner Comments: I'm a watch guy. I wanted a quality mechanical tool watch to wear for every day use and not have to worry about it. 


This watch is it! 

No nonsense watch with quality movement, solid and handsome . Comfortable and perfect size. Love it

Sinn 856 Tegimented on bracelet

"Sinn 856 Tegimented on bracelet"

Verified Watch Owner Comments: I am rough on watches - my Rolex Sea Dweller and Explorer are good watches but they scratch up easily.


I wear a fully Tegimented Sinn - it's great and cannot seem to scratch.  It is also easy to read and I like it better, seems just as accurate.

An Elegant Simple Timepiece

"An Elegant Simple Timepiece"

Verified Watch Owner Comments: I have had the watch for over a month now and have fallen more in love with it everyday.

I live in a fairly humid environment and the Argon inert gas dehumidifier works very well. The watch is lightweight and hasn't started to show any signs of wear or scratching. I am very hard on watches and frequently have to replace the crystal.

However, the Sinn rugged design has proved to be the perfect fit for me. I highly recommend the Sinn name to anyone that asks me about the watch.

Best Watch I have ever owned.

"Best Watch I have ever owned."

Verified Watch Owner Comments: This is my second Sinn, I bought the 556i and loved it so much I had to get it's big brother the 856 non-UTC.

The watch is superb, fit and finish as good as a Rolex, just without the shiny bling. The tegimented steel is a nice gun metal grayish color, satin finish and feels buttery to the touch. Bracelet adjusts easy and fits well and is extremely comfortable. Out of the box the watch was running +5 seconds a day, and now it has slowed down to +3, that's Chronometer range.

I can't think of any of my other watches, Rolex, Omega, Tag, Tissot, Grand Seiko, Citizens that are even close to having the quality bang for your buck that these Sinn do.

Quality product

"Quality product"

Verified Watch Owner Comments: I chose this watch because I wanted a tough automatic for every day wear. I wanted good lume, a date function, and an easy-to-read dial. This watch delivers and then some. 


It's more attractive than I expected and the finish is impeccable. It's the perfect size as it is feels smaller than its 40mm size but doesn't look undersized on my wrist. Accuracy is good at about +5 sec per day, and it's still new. 

My experience with WatchBuys was first rate and I highly recommend them. The bracelet tapers a bit more than I realized so I ended up switching it for an aftermarket leather band and I couldn't be happier.

856 Non-UTC

"856 Non-UTC"

Verified Watch Owner Comments: Since first receiving the watch it has rarely left the wrist and I own a number of watches.

Timing is gradually becoming more accurate, approximately 6+ sec. per day after a week. The tegimented case and bracelet have a unique, appealing appearance and the watch fits very comfortably on my 7 1/4" wrist. The dial is everything it's written up to be: strikingly visible at all angles with a good lume application.

My only critique is with the bracelet clasp as I would like to see the ends more contoured to fit flush against the bracelet. This is a minor issue and should not deter anyone from purchasing this model.

Great watch

"Great watch"

Verified Watch Owner Comments: Tegimented steel is more flattering in person and less "dull" than I imagined. So far (3 months) it has taken a real beating - bracelet, crystal and all. I can't find one scratch or dent.

I am an anesthesiologist and wear this daily - so far it has proven slightly more resilient than expected. The bracelet is very easy to resize with included tool. Date is easily viewable. So far it seems to run slightly fast such that I notice its 30s-1m off at end of the week. overall very happy with purchase, very happy with look of watch and decision to choose this as my primary watch

Sinn 856 Non-UTC

"Sinn 856 Non-UTC"

Verified Watch Owner Comments: I bought a Sinn 656 about a year ago. It is a great watch but I wanted something a little bigger. I also managed to scratch the 656 case so I also wanted a watch with a more durable case. The 856 non-utc was the perfect next watch for me. I had the pleasure of attending the Chicago Road Show last month so I was able to look at the watch before I bought it. The road show was a blast. I learned so much. It is nice looking at pictures on the internet but there is nothing like seeing the watches in person while being able to ask experts questions. I highly recommend the road shows. The 856 non-utc is a simple, elegant watch that goes with everything. It is easy to read and feels just right on my wrist. The 856 has a slightly darker finish than the 656 due to the tegimented case and bracelet. I like the darker look and the tegimented steel make this a very tuff watch. I also like the larger date window on the 856. I have read that some folks do not like the placement of the date window but ... - more details

Must be seen and held to be appreciated!

"Must be seen and held to be appreciated!"

Verified Watch Owner Comments: The fit and finish of this watch are excellent. I have had it for just over a week and have worn it daily.

The 856 is not too heavy and relatively thin for an automatic, so it wears comfortably (on the steel bracelet). Even as a "simple" pilots watch, others have noticed it, and commented on the watch. The dial is clean and easily read, the Tegimented steel has a brushed look to it that is definitely unique. As expected with the Sinn dual coated crystal, when clean, it is almost like nothing is covering the watch face.

Well executed, classic design that has been over-engineered (tegimented steel, antimagnetic, copper sulfate capsule for moisture control and monitoring) by Sinn into a great timepiece.
