Product Details

We love the Sinn 856 Black Series - its all black finish gives it an attitude that's hard to miss.

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.

The Sinn 856 Black capitalizes on all that's great with the standard Sinn 856, but adds a black case created with Tegiment PVD technology. 

A small yellow-green hand indicates the second time zone on a small 24-hour scale.



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 black Tegiment PVD technology and 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.

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.

Awesome pilot tool watch

"Awesome pilot tool watch"

Verified Owner Comments: I did a lot of research prior to buying the Sinn 856 UTC Black Tegimented on Bracelet. I wanted a tool watch for everyday wear that could go to work with me, go camping, fall in a river, make it through Chicago winters, and go out with me for drinks after. I also wanted something accurate, and highly engineered. My price range was $500-$5000. After wearing it everyday for the last three weeks, I gotta say I'm very happy. Out of the box, it was running and the time and date had been set by the Watchbuys crew, which was very cool. The watch feels super solid and smooth, and the Tegimented surface looks way better in person than in online photos. Thus far the finish on the case and bracelet has been super durable. I'm pretty rough on watches. I wear it all day and have only a couple very very fine hairline scratches on the clasp. The ETA 2893-2 movement is great so far. Very smooth and gaining about +2 seconds per day on average. I'm impressed. The lume is bright when charged, and the... - more details

Great Looking Watch (more)

"Great Looking Watch (more)"

Verified Owner Comments: I have been wearing this watch 24/7 since I bought it this month. It goes with me to the shower, desk diving on my laptop, hiking, rubbing it back and forth my keyboard.

My laptop itself is coated black and due to the bracelet, it has worn of the coating on the laptop. But on the bracelet itself, it is as good as new. However, I was surprised to find that the Watch dial's pvd coating has slightly worn off and showing the tegimented grey. I have no personal qualms with this, as I like that it shows that it has been worn and beaten and used, however, I had the impression that the PVD coating on Sinn watches are very durable and would withstand a lot more abuse.

Overall, I love it, but I did have the impression that the PVD coating would last longer than 3 to 4 weeks of continual wear.

Love the watch but it has minor flaws

"Love the watch but it has minor flaws"

Verified Owner Comments: As the title says, I do love the watch. It looks great and is clearly of high quality. However, after wearing it every other day for the last month, two things stand out to me. First, it easily gains 20+ seconds a day, and sometimes it seems like close to a minute. Of course it's an easy fix to pull out the crown and wait for time to catch up (meaning it's less annoying that a watch that loses time), but still, it seems like it gains more than it should. The second issue concerns the clasp on the bracelet. The finish seems not as hard as advertised...as I said, I've worn the watch every other day for the last 30 days, with many of those at my desk. The clasp shows many small scratches, and the finish on the edge has already worn quite thin. I took a picture of this but apparently cannot upload it. It concerns me that at a contact point, a formica-topped desk is able to very visibly wear through the finish, and I wonder what the clasp will look like in another few months (guessing n... - more details

Great looking and very functional watch

"Great looking and very functional watch"

Verified Owner Comments: I have to say that I bought a Sinn Diapal some years ago, loved the watch but found it was just too thick for my taste. But I very much liked the quality and general fit and finish of the Sinn watch and resolved to buy another one day. That day came a couple weeks ago when I decided to buy the Sinn 856 UTC in black Tegimented on a bracelet. WatchBuys is great to deal with, I had a number of WatchPoints from the purchase of my Diapal some years ago (they don't expire!) which lowered the price of the watch and the shipping. It was delivered the following day. The Sinn box, documentation and included screwdriver/pusher tool hinted at the quality of the watch within, and I was not disappointed! Great look and feel, the clasp mechanism is crisp and positive, the crown and movement are smooth to unscrew and set. The matte black finish of the case and dial contrast beautifully with the bright white and extremely legible hands and numerals. It wears a bit larger than a 40mm watch might, for in... - more details

856 UTC S

"856 UTC S"

Verified Owner Comments: This is a very nice watch. I just received mine earlier this week, and it's every bit as good as I expected. The picture really doesn't do justice to it. It's not some kind of gunmetal gray, and the dial is not blurry. The color is a matte black, even under daylight, and the dial is a matching color. Under some lighting the crystal, or perhaps the anti-reflective coating, gives the dial a blue sheen. It's also legible at very extreme angles and in all kinds of lighting. The anti-reflective coating doesn't eliminate all reflections, but at many angles the crystal seems to disappear completely. The lume is bright if charged, but sitting in a windowless office all day doesn't charge it, so I haven't seen much of it yet. The white lettering and markers have crisp edges, and the yellow UTC pointer is fairly subtle, but easy to read. The date indicator is the only weak point: it's a bit hard to read with older eyes, as it's somewhat shadowed in a fairly small window. And despite comments I'v... - more details
