Product Details

The Sinn 856 has become a gold standard for an attractive, highly legible and uncluttered watch in a bulletproof case (fully Tegimented).

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 case size is a perfect 40 mm which provides an ideal fit for the majority of wrist sizes.

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. Black Sinn calf leather strap with tang buckle.

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.

Long-Awaited and Worth the Wait

"Long-Awaited and Worth the Wait"

Verified Watch Owner Comments: I’d had my eye in this watch for a long time and was very happy when it became available again. It’s exactly as other reviews had described it and is a joy to wear and use. The service at WatchBuys was terrific.

Great field watch

"Great field watch"

Verified Watch Owner Comments: I've got a larger wrist at 8 and find this to be my perfect field watch on a nato. The non-UTC face is much better balanced and legible in my opinion and has a decent amount of presence even on a large wrist. It wears small as far as comfort but the large face makes it very legible with the stark contrast the matte black dial and the bright white hands, markers and Arabic numerals. It's an attractive watch where less is more. Very clean and understated, yet I find myself staring at it none the less. If you're looking for something rugged and uncluttered with classic proportions, look no further. It's a Sinn, so you know the quality is there. Mine is unsurprisingly running at +.5 SPD given the well adjusted, top grade Sellita movement. Bonus is the tegimented treatment to the submarine steel case. I changed out the strap upon receipt and thought I'd scratched the back of a lug with the spring bar. Upon inspection, I couldn't find any marring of the finish. Tough stuff! I'm sure it... - more details

Sinn’s Rolex Explorer

"Sinn’s Rolex Explorer"

Verified Watch Owner Comments: Some might call this a pilots watch. I’d call it an adventure watch. With all the tech of a Rolex and Omega combined, it’s the perfect EDC adventure watch. You can dive with it, hike with it, or wear it to office. Super comfortable and hardcore.

Whether on band, strap or nato you can’t beat it. If there is a single flaw I’d say the lume could be improved. Would love to see one with a red or orange second hand. This watch is one you could put on and literally never take off.

Why spend more money for a lesser luxury watch?! Don’t. I’ve owned them all. This is the he way to go!!

856 Tegimented on Strap

"856 Tegimented on Strap"

Verified Watch Owner Comments: I love the watch, it’s rugged and accurate and the design is classic and easy to read.

The guys at Watchbuys could have asked me if I needed a long strap it would have saved me the expense of having to replace it.

The 856 Is A Keeper

"The 856 Is A Keeper"

Verified Watch Owner Comments: From the structural integrity of the case and the Tegimented treatment, to the easy to read dial, it’s a pleasure to wear such an understated watch.

My son thought so as well hence, the Sinn 856 I bought from WatchBuys almost three years ago is now on permanent loan to him. I had no choice, so I bought another Sinn 856 for myself!

Sinn 856

"Sinn 856"

Verified Watch Owner Comments: this time piece is awesome, I've had Squale, Oris, Hanhart, Tag, to name a few. I could tell when I opened it up that this was going to be my favorite time piece. Quality is 2nd to none. Absolutely love the simple look of this watch. Fit is Perfect!!!! lume is top notch...

WatchBuys guys are great too...

Surprisingly ferric

"Surprisingly ferric"

Verified Watch Owner Comments: I have been wearing my Sinn 856 for about a month. It sits well on the wrist for every day use. I was interested in it's anti-magnetic label (80,000 A/m or 1000 Gauss or 0.1Tesla) without knowing what that really means because I do work around MRIs (0.5-1.5 Tesla).

I have worn several watches around MRIs such as Apple series 2, Bulova 267 Hz, and Zodiac Orange Dive. I know that if I get too close, the watch would stop but they have so far restarted as I move away from the MRIs. What was unexpected about the Sinn 856, was that the pull on the case near the MRI was very strong. I did not expect the steel case for an anti-magnetic watch to be that ferric. I realize that anti-magnetic usually means the mechanism is protected somehow (like in a Faraday cage) but why would the case made to be so ferric?

Sinn 856 on leather strap

"Sinn 856 on leather strap"

Verified Watch Owner Comments: I was considering both the Sinn 856 UTC and the 856. I ultimately went with the 856 because for me the UTC dial was a little cluttered with the 24-hour scale and the second time-zone hand was hard to read and not lumed.

The 856 has a beautiful uncluttered highly legible dial that for me made the difference. Both share the very well finished case from SUG with the Tegimented technology and drilled lugs which for me is great because I usually remove the OEM strap and stress about scratching the case.

Dehumidifying technology and anti-magnetic properties and nice size watch that I feel you can wear under a dress shirt or on a hike.

This was my second purchase from Watchbuys and as with the first the customer service before and after was outstanding and I would recommend them.

My favorite to wear

"My favorite to wear"

Verified Watch Owner Comments: I own a Dornbleuth and a Nomos but this is my favorite. Like someone else mentioned, I can wear this watch anytime without worrying whether I’m going to damage it. Surprisingly, the leather strap can resist almost anything including water but I wouldn’t submerge it. The deployment clasp is a must and one of my favorite features of the watch but an option for an added price.

great watch, great buying experience

"great watch, great buying experience"

Verified Watch Owner Comments: This is a very readable and attractive dial. I wanted a sturdy, scratch resistant watch with great legibility. I wanted to be able to quickly and precisely observe the minutes hand and markers. This pilots watch exceeds most of my expectations. So far accuracy is acceptable, at +8 seconds per day. It may settle down some in the coming months.

Matt was very communicative and helpful throughout the buying process. In large part because of him, I will use Watchbuys in the future.

The. 856 Won't Disappoint

"The. 856 Won't Disappoint"

Verified Watch Owner Comments: Great design , easy to read dial and keeping good time...+ 2-3 seconds a day. I like the Technology that Sinn builds into the watch.. So far the tegimented case appears bulletproof... I have found the strap too stiff..Within The first few days , the inside leather keeper developed a small tear from simply putting the watch on..I fixed it with a small piece of electrical tape and it appears fine.. I would buy the 856 again and recommend it to people...I bought a 656L from WatchBuys about five years ago and enjoyed it too. For my money, Sinn represents great value.

Sinn 856 on Strap

"Sinn 856 on Strap"

Verified Watch Owner Comments: My first Sinn and couldn't be happier. Perfect size and heft- I have average wrists and it sits perfectly. Not too ostentatious and not too small.

I originally tried the 556a and found it to be slightly small (though my wife liked it and it would have looked great on her). The dial couldn't be more classic or easy to read. I was worried I wouldn't like the titanium-esque color of the case. No worries now. It matches the face elegantly.

WatchBuys experience was fantastic. Great communication and easy shipping. Only downside was that I wished I could have used the FedEx option to reroute the package to a specific site because I knew I wouldn't be home. I guess you have to be a repeat customer for that option. All the more reason to get another watch!

Sinn 856

"Sinn 856"

Verified Watch Owner Comments: Having owned and discarded several inexpensive (and low quality) watches in the past I decided to purchase a high quality watch that would last years (if not decades).  I had three criteria:  1) well made, high quality, and durable 2) understated and simple. I am not interested in impressing people with how expensive or complicated my watch is. 3) simple and able to fit into multiple social situations ranging from casual to formal.  I do not desire to purchase multiple watches. The Sinn 856 fulfills all of these criteria. Within a week of receiving my new watch I went on a four day backpacking trip on the Appalachian Trail with my watch strapped to my wrist the entire time day and night.  The 856 came though having kept near perfect time (general +1s/day) and without a single mark on it.  The 856 is indeed simple, high legible, and understated. Its quality is not seen in a flashy case or a complicated movement, but rather becomes apparent under close ... - more details

Solid daily watch

"Solid daily watch"

Verified Watch Owner Comments: I have several different watches from other European watch makers and the Sinn 856 is my day to day go to watch. Simple, classic styling, nice movement, sturdy and easy to read. I have worn it to the office, hiking, on industrial construction sites and it fits every occasion.

My father in law swayed me from Swiss brands to this German brand and I couldn't be happier. The watch was shipped on time and it arrived as I expected.

This will not be my last purchase from Watchbuys.

A great watch that's a great value

"A great watch that's a great value"

Verified Watch Owner Comments: I own a really nice Rolex but I wanted a watch that I don't feel the urge to take off if I'm about to do something that might beat it up. After a lot of online research, I settled on a Sinn 856. 

I couldn't be happier with the watch or the service that I got from the supplier, WatchBuys. I like it better than the Breitling Super Ocean and the Omega titanium SeaMaster that I previously owned - and the Sinn costs a lot less. 

Frankly, I like it better than my Rolex which looks really over-priced in comparison to the Sinn. Don't be misled by the fact that Sinn doesn't advertize much in the U.S. They're the real deal.

My Perfect watch.

"My Perfect watch."

Verified Watch Owner Comments: The watch is 40mm not 37.5 like the 556a, a must for my 8" wrist. Does not have the UTC, so easier to read dial, hard case, humidity warning. 

I can not stress enough, you to make time to go to the Road show. See them up close, put them on. The 556 would have been a mistake. I had notebook pages of questions Matt and the others answered-bezel mating, modification to movement hardness.

I was able to get all my questions answered and am very very happy with this watch. 

Well done.

Amazing watch and value

"Amazing watch and value"

Verified Watch Owner Comments: This is the only watch worth getting within $1,000 of its price. Anything else you get in this price range is just throwing money away (unless you get another Sinn of course.)

This watch would easily fit in among high end brand watches at a jewelry store at a fraction of the price. Pros: Clean, legible dial Great size, works as a sport watch and dress watch Scratch resistant Good weight, light enough to feel comfortable yet heavy enough to feel high quality 

High quality leather strap Just an overall beautiful watch Cons: Don't like the copper sulphate capsule, would prefer not to have a hole in the side of my watch Not a fan of the sideways date.

Sinn 856 Non UTC

"Sinn 856 Non UTC"

Verified Watch Owner Comments: The watch was delivered right on time as promised. It matches up with the description perfectly and is absolutely perfect.

The look and feel of the watch are just what I was looking for and the price was very fair considering that other similarly styled watches sold through retailers cost more than twice as much.

Watch Buys made the process so simple and their personal contact with me was really a nice touch. Since it is an on-line purchase they contacted me directly and talked me though what would transpire once the order was processed. I would buy another Sinn watch through WatchBuys once my Watch Fund fills up again.

I think the Sinn product is one of the best out there.

Outstanding Service, Outstanding Watch

"Outstanding Service, Outstanding Watch"

Verified Watch Owner Comments: The 656 was nearly my perfect watch, but I always desired a slightly larger, tegimented case. It took Sinn some time (+10 years), but they finally came through.

They added the inert gas and copper sulfate technologies as well as "upgraded" the movement to an ETA 2892. It appears to be gaining 7-8 seconds per day, but may settle in as it is still new.

Perfect watch for me, but just as important was the excellent service provided by Matt and Rob. This was my first purchase from Watchbuys, but it will certainly not be my last!

Great watch, better service

"Great watch, better service"

Verified Watch Owner Comments: This watch did not disappoint. Understated, tough, functional, 2892 movement. Just a beautiful timepiece that will last, and last.

Exceptional customer service at Watchbuys. Matt was great answered all questions timely. Thanks

Sinn 856 (NonUTC)

"Sinn 856 (NonUTC)"

Verified Watch Owner Comments: A fantastic watch. I wear it daily on a Sinn silicone strap and it is perfect.

Understated,comfortable, functional and bombproof. In my opinion, excellent value.
