Sinn 856 UTC Tegimented on Strap
Product Details

The Sinn 856 has become a favorite for those seeking a dual time zone watch.

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.

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

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

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

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.

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

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, 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 service center, RGM Watch Service located in Pennsylvania. This added service saves our clients the time and effort of returning their watches to Germany for repair. This benefit 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.

Please also 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 contact us and we'll provide instructions for shipping the 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 FedEx. 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. Among the more popular features 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 layer has a hardness of 1,200 Vickers which is five times harder than standard steel (and on some Sinn models even higher - up to nine 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 primary advantage to a Tegimented case is extreme resistance to scratches and other case abrasions.

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 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.

Another advantage to this technology is that it prevents the dial and crystal from fogging. 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 knowing so – frequent high altitude flying, metal detectors, audio and video equipment, medical equipment and computer equipment to name a few.

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, "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.

  • 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, and each movement is a certified chronometer.

By using this type of movement, Sinn is able to fill the watch with oil, which has the double 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.

  • View Sinn watches in the EZM Series.

TESTAF Certified Pilot's Watches

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.

The new "Technical Standard for Pilot's Watches" (TESTAF) was developed by the Aachen University of Applied Sciences and establishes the suitability for professional use as a pilot's watch.

Watch Reviews

Customer service

"Customer service"

Kenneth P

Comments about this watch: I have been extremely impressed with the cutomer service before and after my initial purchase. I am in the process of another purchase from watchbuys and Tim and the guys are being patient through my selection process. I've read some reviews on the watch forums about the lack of service here but find that not to be the case.

My expectations are high and have been met. The only thing I would like to see is a consistant road show to Florida, there are several to California this year maybe one could be changed to Florida.

Excellent watch, great service.

"Excellent watch, great service."

C. Li

Comments about this watch: I would like to thank the very helpful WatchBuy staff, who responded to my comments by swapping the strap to the short version.

The watch is perfect size and thickness for my very thin and flat 6.25" wrist. It is extremely well made, and looks better than I expected. I like the UTC complication, without it the watch might look a bit plain in my opinion.

In terms of accuracy, It's probably still setting in but I'm getting +/-2 seconds per day mostly, so it's pretty good!

Sinn 856 UTC

"Sinn 856 UTC"


Comments about this watch: I received my Sinn 856 two weeks ago from WatchBuys. They were very helpful throughout the entire process. Excellent customer service.

The watch is perfect! It has kept excellent time, and the finish is superb. I have received many compliments on the watch, and would recommend it for anyone looking for a high quality instrument watch that can be worn on a daily basis.

Simplistic elegance.

"Simplistic elegance."

Jonathan M

Comments about this watch: This is my 3rd Sinn. I also own a U1 and a 556.

Love all three watches, but I am thinking of selling my 556 because the 886 is basically an upgraded version of it that contains a lot of Sinn's great proprietary technologies.

This watch rides perfectly on my smaller 6.5" wrist. It's light and keeps +5s to the day. I love simplistic easy to read tool watches, and as far as they go, the 886 is king.

Highly recommended.

I travel often and make great use of the UTC feature, but even when I'm not traveling, it's still useful as a 24-hour clock.




Comments about this watch: Have had for 6 months, amazingly accurate.

Have gotten more compliments on this than my Explorer II- have with small clasp rubber band-Awesome.

Thinking about adding another Sinn to my collection

Excellent, efficient service

"Excellent, efficient service"

Carlos R

Comments about this watch: Just what I was looking for: no nonsense looks, yet elegant. It is an instrument for telling time and not an oversized, gaudy piece of jewelry.

The UTC component adds functionality for world travel. I am very pleased with it.

WatchBuys provides excellent and efficient customer service.

Outstanding watch

"Outstanding watch"


Comments about this watch: This is the third 856 UTC I have purchased.

My oldest son snarfed the first one. My youngest son slipped off with the second one. I guess someday I'll lose this one to my grandson.

I'll just keep buying more!!

856 UTC

"856 UTC"


Comments about this watch: I wear it always - I work with my hands, fly and am active outdoors.

This is not showy, heavy or cluttered. It is easy to read in any light condition and looks great. And, I see, it's gaining value.



Phil L.

Comments about this watch: I had a hard time deciding between the UTC/non-UTC versions of the 856 - and I suspect that many before/after me did and will also. In the end, despite the 'clean' look of the non-UTC version, it was just too plain for me. Turns out I made the right decision after all, as the 856 UTC dial is beautifully proportioned, with absolutely nothing looking cramped or out of place.

The UTC hand is visible but discreet at the same time, and makes for a nice compass marker too, when you are using the watch to orient north/south.

Just a classic!!



Emil S.

Comments about this watch: My first of three Sinn watches and definitely one of my favorites.

I was drawn to the 856 because of its clean look and slimmer profile which is perfect for wearing it under a dress shirt. The dial is very legible and the lume is good. The UTC function is an nice addition as my work requires me to travel occasionally.

Another great Sinn watch!

"Another great Sinn watch!"

Jerry W

Comments about this watch: The 856 UTC is my second Sinn after the U1 and like the U1, I find the 856 UTC very purposefully designed with no unnecessary gimmicks. Just really useful technology for a great price!

It is a very striking looking watch and the 40mm case size is perfect. I alternate various straps on it including some custom made leather straps and it's already a favorite in my rotation after 3 weeks.

And again, Matt and the crew at WatchBuys offer fantastic service!

Sinn 856 UTC - Superb

"Sinn 856 UTC - Superb"


Comments about this watch: This is an elegant, simple watch that is not ostentatious. It does what a superb watch should; keep very good time, and do so for generations.

I require both UTC and local time readily available; this has no clutter, showy complications. Perfect.

Perfect Sports Watch

"Perfect Sports Watch"

Robert J W

Comments about this watch: This great watch is unique, rugged, readable and superb for all outdoor activities.

I use mine for biking, hiking, & shoveling in the garden. You name it. Bang it up, get it wet, it's a survivor. If you don't need a chronograph or bezel, the simple instrument design is just right. You will draw many questions and compliments, too.

You may find, like I did, that there is another strap you prefer to match it with.

Great everyday or tool watch

"Great everyday or tool watch"

Randy M

Comments about this watch: I'd recommend the 856UTC to anyone.

The dial and hand design on the 856 is very easy to read, and the lume lasts a good 8 hours if its "charged" for a minute or so under a flourescent light. The 2nd time zone is great for travel or any profession or hobbly that requires the use of UTC time, ie: pilots or ham radio operators. Or for just keeping up with what time it is where friends or relatives live.

Accuracy is good, mine gains an average of 5.7 seconds/day when rested face up on the dresser overnight. Gain varies according to rested position, and 5.7 s/d is the fastest it runs in any position. Some other overnight positions would result in less overall gain, but since I'm satisfied with any mechanical watch that stays between 0 and +6 s/d, I prefer to lay it face up flat on the dresser when I take it off.

A Fantastic Watch

"A Fantastic Watch"


Comments about this watch: This is a fantastic watch. It is very accurate, great looking and comfortable.

The anti reflective crystal is invisible in most conditions and really makes the dial look great. I don't need the UTC, however it does add an interesting element to the watch. It is comforting to know that this watch can handle conditions that I would not expose myself to.

I am extremely happy with my purchase.

Comments about this watch: This is one of three Sinn watches that I own and of all the watches that I own, it may be my favorite. This watch is perfect for both formal and casual wear and its second time zone feature is very handy for anyone who travels between time zones.

 I've received a number of compliments about this watch ... I'm very pleased.

Comments about this watch: This is my third Sinn watch and like its stable mates the 144 and U2 it does not disappoint.   The first thing that struck me upon removing it from its box was how light it was. I was sure that with the steel case it would feel heavier, but I was really surprised by the light weight. Accuracy is on the average of -3 or -4 a day. I will have to do some more in depth testing to confirm that. Fit and finish is typical Sinn (perfect). Once again Sinn has integrated the Copper Sulfate anti moisture capsule technology into one of its products. A little unexpected as this is a pilots watch and theoretically not subjected to much moisture, but welcome just the same.   As a pilot, I use the UTC function all of the time as all times used by the FAA are in Zulu (UTC) time. Most of my watches have a second time zone feature for this reason. Another feature attractive to me as a pilot is the anti reflective coating on the crystal. It makes cockpit readability of this watch much, much ea... - more details
