Product Details

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

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.

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-green 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.

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.

Absolutely first class experience

"Absolutely first class experience"

Verified Watch Owner Comments: First, the process and experience from buying through Watch Buys was nothing short of "this is how I wish everyone worked.”

As for the watch, I really am enjoying it. Both the aesthetics and durability of the tegimented steel has thus far been flawless. Watch is keeping great time, it’s easy to read (except the UTC function, which is sometimes obscured by the main hands), and the band adjustment couldn’t be easier. I don’t have extensive watch experience. I think I’d prefer a domed crystal, but at times the flat crystal is more pleasant than otherwise.

Half tongue in cheek, I wish I liked the watch less because I’d be less tempted to add more.

Sinn 856 UTC

"Sinn 856 UTC"

Verified Watch Owner Comments: Wonderful tool watch. I purchased the bracelet separately, and prefer to wear it that way - I highly recommend it! I think Sinn got it just right with the dimensions and dial design. I usually go for larger watches, but this one fits my 7 wrist perfectly!

And the purchase experience with Watchbuys has been great, as always!



Verified Watch Owner Comments: Once up and running, my 856UTC Tegimented is exactly what I’d hoped for. Simple and beautifully crafted, it retains its accuracy up to five seconds over a week. The large face is readable under all conditions of light. I thought I might replace the Sinn band with my old leather band, as it was already broken in and soft however the new band is gorgeous, and is breaking in beautifully.

The service at Watchbuys is outstanding, I don’t believe I’ll look for anywhere else to buy watch in the future. They were on top of the purchase from the moment of inception until I received it. Thanks.

fantastic, no-nonsense, unpretentious, rugged daily wear

"fantastic, no-nonsense, unpretentious, rugged daily wear"

Verified Watch Owner Comments: Bought this for my daily wear watch. I wanted a watch I wouldn’t hesitate to wear about my usual day-to-day. The 856 UTC is my first Sinn, and this was my first experience with Watchbuys. I love the watch, and the purchasing experience via Watchbuys was a breeze. After placing my order, someone from WatchBuys called to confirm the purchase, verify my shipping preference, and answer some questions. The standard delivery option was quick, just a few days. This is a striking looking tool watch. The dial on the 856 UTC is easy to read, and all business. The UTC hand and markings give the dial just enough color and pop for my taste, and the UTC function is handy. I’ve never been a fan of gigantic watches. The 40mm 856 UTC sits comfortably on my 18.5 cm wrist. Not too large, not too small. My first impression of the watch was that it felt lighter and slimmer than I had imagined. The fit and finish of this watch, at this price point, are excellent. This is a fantastic, no-nonsense, unpr... - more details

Sinn 856 UTC

"Sinn 856 UTC"

Verified Watch Owner Comments: Decided to go in the German tool watch direction, decided on Sinn and chose the 856 UTC for several reasons

1) case material, hardened steel should age well and has matte non chrome non brushed non bling finish I was looking for

2) Dial has vintage aeronautic gauge design

3) didn’t want a rotating bezel on this watch , have a Seamaster for that, prefer the UTC numbers on this dial for the couple times a year I change time zones.

4) size, 40mm full size but not oversized for my modest size wrist

5) leather band is well made and good match for watch 6) Sinn -some history and tech

Great everyday/travel watch

"Great everyday/travel watch"

Verified Watch Owner Comments: Love the wear and subtlety of this watch as an everyday piece on 7 inch wrist. Looks great on both oem strap as well as everything I have put it on this far.

Watch buys was a pleasure to deal with especially as somebody with a military address when it can be difficult to get things quickly. Hughly recommend for those looking for a true tool watch.

Amazing watch!

"Amazing watch!"

Verified Watch Owner Comments: This is a great watch with UTC dual time function, anti-magnetic, and ruggedness for a decent price.

Watchbuys customer service is amazing with their follow up service. Highly recommended brand!

Superb timepiece

"Superb timepiece"

Verified Watch Owner Comments: Awesome watch, perfect in every way.

Watchbuys got the watch to my house in just 2 days!

Go to for day to day

"Go to for day to day"

Verified Watch Owner Comments: Purchasing was a snap and I really appreciated the courtesy follow up call as I am a new customer. The piece itself is a fantastic example of some fun engineering. As I am an engineer and wanted something that kept time well, two zones, scratch resistant case, this was the logical choice.

Watchbuys also sold me a deployant clasp. As I ordered what I thought would be the one most complimentary to my 856, they communicated again to make sure and corrected my error in buckle finish choice to more closely match my 856. Thanks again and consider this the first of a few purchases.

Perfect everyday watch

"Perfect everyday watch"

Verified Watch Owner Comments: This is my new favorite watch. Sturdy, accurate and looks great. I followed by my purchase with the matte finish clasp and it's now perfect.

Watchbuys contacted me to confirm my order and checked that everything was in order before shipping my watch. Great customer service. I'll definitely buy from here again.

Sinn 856 UTC - Great watch!

"Sinn 856 UTC - Great watch!"

Verified Watch Owner Comments: This is my second Sinn as I gifted my 756 Duochronograph (pre-Tegiment) to my son. The 856 UTC has all the features that I need considering the number of time zones that I cross. Durability, as with the 756 is top notch. Accuracy so far is excellent and the thinner case provides a very comfortable fit. You also don't get the sensation of the rotor spinning as with the 756. Lots of compliments from those unfamiliar with the brand. Once I add the deployant buckle, it will be perfect.

My experience with Watchbuys has been excellent. Immediate response to questions and follow-up on the order. Highly recommend this watch and Watchbuys.

Sinn 856 UTC Tegimented

"Sinn 856 UTC Tegimented"

Verified Watch Owner Comments: Great looking watch with outstanding detail and build quality. UTC complication moved to the inside is a clever idea and easy to read. Classic B/W pilot style with that slight attitude in the flo yellow detail.

As usual, Watchbuys is great. They have the right stuff, great service and fast delivery. I ordered late yesterday afternoon about 2 mins before the FedEX cutoff. Watch was on my wrist the next morning at 10:15. Kick ass. I'm rockin' my first Sinn!

Incredibly clean look, couldn't be happier

"Incredibly clean look, couldn't be happier"

Verified Watch Owner Comments: Upon placing my order, I was contacted by an employee at WatchBuys to confirm the purchase and make sure the watch would be shipped exactly as I wanted it. We ended up changing around the band and discussed some things as simple as winding and wearing the watch as this was my first automatic purchase. Once the watch arrived, I opened the box and found an incredibly clean and well packaged time piece that looked even better in person than I could have imagined. I love wearing this Sinn 856 UTC- it is super clean and feels very hearty. The tegimented case fits in perfectly with my active lifestyle, and with the silicone band I have no worries about getting it wet or going fully submerged with the watch. And the best part... this watch fits in just as well when we go out for a nice dinner. It just looks good.  I was looking for a do-everything watch that looked great and functioned flawlessly... I was not disappointed! And the customer service from Watchbuys was incredible from... - more details

Sinn 856 UTC Tegimented on Strap

"Sinn 856 UTC Tegimented on Strap"

Verified Watch Owner Comments: Very, very pleased with this watch. Very easy to read with its bold hands and face. I've already had an incident that would have scratched a lesser piece, but not a mark on this watch.

Wear the watch constantly except when sleeping. After three weeks of ownership, the watch is running about 4.5 sec fast per 24 hrs. The purchasing experience was top flight. Matt graciously answered all my questions over a two or three day period. Watchbuys was having free next-day shipping when I purchased, so that was a nice little perk as well.

Will definitely purchase another Sinn from Watchbuys in the future.

Customer service

"Customer service"

Verified Watch Owner Comments: 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."

Verified Watch Owner Comments: 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"

Verified Watch Owner Comments: 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."

Verified Watch Owner Comments: 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.



Verified Watch Owner Comments: 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"

Verified Watch Owner Comments: 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"

Verified Watch Owner Comments: 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"

Verified Watch Owner Comments: 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.



Verified Watch Owner Comments: 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!!



Verified Watch Owner Comments: 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!"

Verified Watch Owner Comments: 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"

Verified Watch Owner Comments: 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"

Verified Watch Owner Comments: 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"

Verified Watch Owner Comments: 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"

Verified Watch Owner Comments: 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.

Sinn 856

"Sinn 856"

Verified Watch Owner Comments: 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.

Sinn 856

"Sinn 856"

Verified Watch Owner Comments: 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
