Product Details

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.

Sinn TegimentTo create this watch, Sinn built on the extremely popular design of the Sinn 856 UTC dual time zone watch and a larger case size and bezel.

On a frequent basis we receive client praise for Sinn's "Tegiment" (hardening) technology, and have heard quite a few stories of watch cases scraped against metal railings, car doors, metal desks, and other more interesting objects with little to no damage to the case.

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.

The case back is nickel free, perfect for those with allergic reactions to case metals. Other features include protection from magnetic fields of up to 80,000 A/m, sapphire crystal with anti-reflective coating on both sides.

Another Sinn engineering feat is the creation of a bezel that is secured by screws.  The inlaid aluminum ring featuring numerals and markers is anodized black for optimal legibility, while the triangle reference marker at 12 is applied with special paint for visibility.

The case features a copper sulphate capsule which reacts with moisture to diffuse and absorb humidity in the watch. This capsule may be viewed through a porthole in the left lug, and over time will turn a deep blue as humidity is absorbed. This technology not only provides a more stable environment for the movement, but also helps to prevent fogging of the crystal when going from hot to cold environments or from humid to non-humid conditions (such air conditioned buildings).
Sinn 857 Dial
This watch has a second time zone displayed by a skeleton yellow tipped hour hand. The second time zone can be set directly through the second position of the crown and uses a 24 hour indication to differentiate AM and PM. 

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, hour markers and the 12. Watch is water resistant to 20 ATM. Watch is fitted with a Tegimented steel bracelet with hex screws and solid end links.

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.

WatchBuys Advantage #7

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.

Solid watch

"Solid watch"

Verified Watch Owner Comments: I’ve been on a wait list for this watch for close to a year. I had wanted the version on the leather strap, but missed that one and chose the fully Tegimented version. This is one solid watch, and the heft is noticeable even in the box. I’ve worn the watch quite frequently since I received it, and in my desk duties that normally really leave tell tell marks on straps and clasps, this one is mark free. This has to be one of the more legible watches that I own. Even at night, it just stands out and is highly visible. As for the accuracy, it tends to run fast, but within tolerable limits. This is my 4th Sinn and they all seem to run fast. I think that’s a German attribute as even my Glashutte Originals, Tutima and other German watches all run a little fast. Personally, I prefer a watch that runs fast to one that runs slow. Guess that’s in my German DNA. If you have the chance to pick one of these watches up, and you need a tough, reliable watch that is no frills and will not let you d... - more details

Customer service is outstanding.

I love it

Verified Watch Owner Comments: I have a tendency toward buyers remorse. I've never had even a twing of it with this watch.

Verified Watch Owner Comments: Easy to order and customer service was great.

Received the watch. Looked great coming out of the box. Came with tools to adjust the bracelet as well as spring bar tool if you wanted to change the band. Highly visible in the dark and keeping great time so far. No problem so far.

Amazing Watch

"Amazing Watch"

Verified Watch Owner Comments: I've owned the Sinn 857 UTC for a month, and it has quickly become my everyday watch. The dial is easily read in a glance, day or night. The tegimented case and bracelet are great. Not a single mark on them.

I highly recommend this watch and Watchbuys.

A watch for every occasion

"A watch for every occasion"

Verified Watch Owner Comments: I have had this watch for 7 or 8 years now. I love it so much that I rarely take it off. Its suitable for every condition. It can be worn in a casual or more formal setting. The outside of the bracelet has suffered some scratchs over the years, but they are hard to notice.

Considering that I have worn it every single day for 8 years and there are only some small cosmetic damages from use now is a testiment to its construction. 10/10 would reccomend.

A tool watch Icon!

"A tool watch Icon!"

Verified Watch Owner Comments: I bought this for my son-in-law on the occasion of his first child and he was overjoyed. It bold but not oversize, intricately and elegantly designed. Dial legibility, GMT feature and tegimented steel steal the deal. This is my 2nd Sinn purchase and I am already planning the next one.

There is nothing that compares in quality and value - the Swiss don't offer tegimented steel!

The Tech You Crave

"The Tech You Crave"

Verified Watch Owner Comments: I had owned a Sinn 856 UTC in the past and loved it, but something about a rotating bezel appeals to me. So the natural progression from here was the 857 UTC, and I am extremely glad I took the plunge.

It has all of the cool Sinn tech I was looking for, in a nice everyday wearability package. Great watch!

857 utc tegimented on bracelet

"857 utc tegimented on bracelet"

Verified Watch Owner Comments: Thanks watchbuys for another great watch. Super legible, large watch with great wrist presence, but wears small and is very comfortable. The bracelet was easy to size, and the watch works flawlessly. The tegimented steel finish is not only tough, but has a cool industrial look that I really like.

Thank You again, Watchbuys.

Excellent Pilot Watch

"Excellent Pilot Watch"

Verified Watch Owner Comments: I'm currently training to be a military aviator and wanted a tough watch with a GMT/UTC complication for use during flight training and beyond, which led me to this Sinn. It's great to read in terms of legibility, UTC is integrated very well on the dial, and the watch is most definitely tough. This Tegimented steel is no joke, I haven't managed to put any scratches on it after a solid three weeks of daily wear. Pair that with the magnetic resistance, and the cool copper sulfate capsule and I'm thrilled. In terms of options I'm very glad I chose to go with the 857 over the 856 to get the bezel. It's very functional (I use it all the time), and adds to the overall tool aesthetic of the watch. I'm also glad I chose Sinn's bracelet. Like I said the Tegimented steel looks and performs great and the bracelet is very high quality in terms of finishing and function. Very happy with the watch and how the Watchbuys folks went above and beyond to answer my questions and were very proactive ... - more details

857 utc ultimate everyday timepiece

"857 utc ultimate everyday timepiece"

Verified Watch Owner Comments: I have worn this watch every day for 2 years, in my collection I don't have anything that is as hard wearing or beautifully utilitarian! The styling is slightly confused , divers and pilots but I actually prefer this to my Rolex Sub!

Beautifully made and it's one of those watches that people own that KNOW about good watches.



Verified Watch Owner Comments: I've been wearing this watch everyday for about 6 months and like it. Very nice size and weight. I bought the rubber (latex) band (large clasp) after the initial purchase and am impressed with it as well.

The steel one was fine, was just looking for something different and the rubber one happens to hold the watch a bit more firmly on the wrist while mountain biking. I do wish the watch was easier to read in the dark. It has decent glow power but the hands are too similar in shape and size to be totally legible in the middle of the night.

Overall, would recommend it though. Very well made.

No regrets...very cool watch.

"No regrets...very cool watch."

Verified Watch Owner Comments: I have had this watch for 6 months now and I love it.

I spent a lot of time looking for a rugged but classy sport watch, and decided on this one over an 856 to get to the right case size. I had some reservations about the bezel, but one thing worth mentioning is that the numbering is in gray, matching the case metal, so it doesn't "pop" as much as it appears to in the pictures. The yellow UTC hand is not unattractive or distracting.

I wear this piece often, and the tegimented case is pristine. Looks great with a pebbled reddish-brown strap. If Sinn would "get the red out" of the U2 model, I'd buy it.

500 days of Sinn

"500 days of Sinn"

Verified Watch Owner Comments: I have had my 857 for about two years and wear it daily.

There is almost no noticeable wear and tear. The clasp on the metal bracelet is the only piece that show signs that it is worn at all. It still catches the eye of watch enthusiasts who often ask who makes it and how nice it looks.

I love this watch. That is the reason I have not bought more watches...I would still want to wear this one.

Great Watch

"Great Watch"

Verified Watch Owner Comments: I love this watch. There are very few true dual time-zone watches that have a diver-style bezel. This is one of them.

The watch is an ideal military timepiece. The tegimented steel is also fantastic. Looks like titanium, but with a more solid feel.

Also, watch is not too big. I also wear a Submariner, and have a relatively small wrist. I was worried it would be too clunky for me, but it's perfect.

Fantastic watch.

"Fantastic watch."

Verified Watch Owner Comments: This really is a nice watch.

If you are thinking about getting one, DO IT! It's well worth the price.
