Product Details

WatchBuys Limited Production - Final Pieces Now Available

This watch was produced by Sinn exclusively for WatchBuys as a limited production model, and the first shipments very quickly sold out.

We recently received the final shipment of this model, and these new pieces are available now on a first come, first served basis.

The Best of Both

Our clients have often found themselves torn between the Sinn 556 Series and the Sinn 856 Series.  Both offer outstanding watches, but the technology is quite different. 

The request that we have received many times in the past is, "I wish Sinn would produce a slightly larger version of the Sinn 556 I with a fully Tegimented (hardened) case and include their proprietary technology."

Welcome to the Sinn 856 I Tegimented.

New Features

The Sinn 856 I Tegimented takes all of the great features of the Sinn 556 I and ups the game.

First, the case diameter is slightly larger at 40 mm rather than 38.5 mm.

Next, the case has been fully Tegimented to resist scratches and abrasions.  Standard stainless steel used by most watch companies has a hardness of 200 Vickers while the Tegimenting process adds a hardness factor of 1,200 Vickers.

This watch also features Sinn's "Dry Hold" technology to protect the movement oils, increase the service intervals and to eliminate crystal fogging.  Sinn uses a combination of a copper sulphate capsule and inert gas to achieve these effects, and increases the warranty to three years.

Finally, this watch increases the resistance from magnetism from 4,800 A/m to 80,000 A/m.

What is the Same as the Sinn 556 I?

Both the design and finish of the dial along with the satinized case finish take their cues from the Sinn 556 I.

Everyone loves the Sinn 556 I dial - its rich, inky black color with just a bit of shine is a favorite, and we've preserved that finish on this watch.

This watch also features indices only with no numerals along with a date indicator at 4.

Finally, all standard Sinn 856 models feature a bead blasted case, but this limited production watch sports a satinized case.

Important features of this watch include:
  • Case made of Tegimented steel with a satinized finish
  • Protection against magnetism to 80,000 A/m
  • Sapphire crystal on front with double AR coating
  • Water resistant to 200 meters
  • Copper sulphate capsule and inert gas to protect oils and regulate humidity
  • SuperLuminova on the hands and hours (glows green)
  • Low pressure resistant
  • Date display at 4
  • Screw down crown

This watch is fitted with a brown, vintage style Sinn strap with black stitching at the lugs and a 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 FedEx 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.

  • View Sinn watches in the EZM Series.

DIN 8330 / 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 existed for example for diver's watches.

The new "Technical Standard for Pilot's Watches" (TESTAF) and DIN 8330 were originally developed by the Aachen University of Applied Sciences and establishes the suitability for professional use as a pilot's watch.

Love this watch

"Love this watch"

Verified Owner Comments: Was looking at a 556i rs when these were restocked and couldn't be happier

Excellent watch

"Excellent watch"

Verified Owner Comments: 556i looks with 856 tech, what's not to like?

Another dynamite timepiece

"Another dynamite timepiece"

Verified Owner Comments: Purchased this watch for my son and couldn’t be more satisfied. Tegimented case is super durable. Watch face is elegantly simple. Very versatile watch. Dress up or casual, this works with any attire. Lume is fantastic too.

A strong blue, unlike my other Sinn’s which glow green. Limited release, I know, but cannot recommend this one enough. Perfect everyday watch.

A step up from the 556

"A step up from the 556"

Verified Owner Comments: I think for the upgrade in features compared to the 556, this 856 model is well worth the price difference. Increase in size from 38.5mm (556) to 40mm (856) is not significant and lug to lug length of 47.5 wears nicely on my 17.5cm wrist.

Will not be my last the looks of the new 105 models.

SINN 856 I - Tegimented

"SINN 856 I - Tegimented"

Verified Owner Comments: I love this watch! It is my first Sinn watch and likely won’t be my last.

The simplicity of the case and the dial really reeled me in on this one.

WatchBuys was excellent to deal with. They even called to verify the circumference of my wrist to make sure that I had ordered the proper length strap. The watch arrived when scheduled and all was handled very professionally and efficiently. I will definitely buy from them again.

Awesome watch and awesome dealer

"Awesome watch and awesome dealer"

Verified Owner Comments: The watch is beyond my expectation. It is simply stunning and cannot help but gush how beautiful the appearance and how it functions as my everyday watch.

Watchbuys is one of the most professional and pleasant retailers that I have experienced so far. I cannot wait for my next purchase! Thanks.

In the dictionary, under “Tool Watch”, there’s a picture of this.

"In the dictionary, under “Tool Watch”, there’s a picture of this."

Verified Owner Comments: Super legible, tough, compact tank of a watch. The tegiment surface treatment is really great for preventing scratches. The lume is really long-lasting.

Mine is a runner too: +1 spd.

Sinn 856 I Tegimented

"Sinn 856 I Tegimented"

Verified Owner Comments: First, if you try to find this watch on Sinn's website, you won't be able to. The reason is, the Sinn 856 I is a special production model (commissioned by WatchBuys in conjunction with Sinn) that's only available on WatchBuys. It's basically a hybrid watch that takes the popular and versatile 556 I and combines it with the technologies of the 856, creating a best of both worlds watch for us. The watch is even more gorgeous in person than it is in the WatchBuys photo. All of the design elements work: it's non-flashy but still very sexy it has a very minimalist appeal to it. I love the flat, matte-black dial, that it has indicies instead of numbers, the sword shaped hands, the fact that the only writing on the dial is Sinn, and the totally unobtrusive location of the date just inside the 4 o'clock position. Even the leather strap is simple, minimalist, and cool, and is of a higher quality than I anticipated. But this watch is more than just a pretty face. The Sinn 856 I has some very... - more details

Sinn 856 I

"Sinn 856 I"

Verified Owner Comments: Very pleased with the purchase from Watchbuys.

The 856 I is a sharp watch that looks great on the wrist. Sinn has really put together one heck of a package with this one. The ultimate example of minimalist design and Sinn advanced technology. The drilled lug holes are perfect for quick strap changes. Leather for dress shirts and nato straps with all other occasions. This one is a understated looker.

Keeping very accurate time as well I might add. Not bad watchbuys and Sinn. I'm sold!! Thanks

Great gift and surprisingly fantastic customer care

"Great gift and surprisingly fantastic customer care"

Verified Owner Comments: I purchased this for my girlfriend. She wanted a simple, clean watch that clearly displayed the time and had nothing else to clutter the dial. She also wanted 1 watch that would work for everything from office work to hiking.

This version of the 856 without hour numbers is perfect clean, robust, fits well on a 6 1/4 wrist. We ordered an additional strap in the short length.

Watchbuys noticed that and called me to ask if they should swap out the stock strap on the watch for a shorter length as well. That was an awesome example of customer service that I honestly did not expect from an online retailer. I ended up liking the watch so much that I purchased a UTC version for myself :)

There’s only one thing wrong with this watch

"There’s only one thing wrong with this watch"

Verified Owner Comments: Given how amazing it looks and how bombproof it is, it’s hard to imagine how I’m going to justify wanting another watch.

Maybe I’ll have to get onto chronographs....

Great watch

"Great watch"

Verified Owner Comments: I had a 556i several years ago. It was a great watch, but this is a step up in every department. The chunky bezel works better in 40mm format, the silky deep black dial even more satisfying sans the 'automatik' text, and the same great satinized case has been hardened and packed with Sinn's tech.

Even the strap is great. When I first saw the design I thought the 4 o'clock date placement was an odd choice, but it actually works really well. This watch is pretty close to prefect. Love it.
