Final Pieces

This limited edition has officially sold out by Sinn, and we have just received the final pieces.

This is your last chance to purchase this watch.

A German Reunification Celebration

The Sinn U1 has long been one of Sinn's best selling models.  With its distinct hour markers and hands, it has become one of the most recognizable German watches in the industry.

It is fitting that Sinn would use their most iconic watch as a tool to celebrate an iconic event in German history.

As Germans celebrate their unification, Sinn also commemorates the occasion as an event that made possible many of their technical achievements of the last decades.

We are pleased to present the final pieces of the Sinn U1 DE (Deutschland), a limited edition of only 300 pieces.

A Partnership of East and West

The partnership between Lothar Schmidt in West Germany and Ronald Boldt in East Germany began in 1998. Lothar Schmidt, owner of Sinn, was in search of a quality watch case producer. Ronald Boldt, an entrepreneur, was in search of a new business venture.

Their first meeting was a success, and the two had immediate chemistry. Their shared technical mindsets proved beneficial as they quickly developed a partnership built on trust.

The pair established SUG (Sachsische Uhrentechnologie GMBH Glashutte) the next year. SUG was the only company in Glashutte at the time dedicated to producing high quality cases for mechanical watches.

SUG Logo

Over the last two decades, SUG has attained a level of technical achievement that sets the standard for technology and quality in casemaking.

SUG has produced watch cases for Sinn since its inception. This partnership would not have been possible without the reunification of Germany in 1990.

In the words of Ronald Boldt: "If ever there were an award presented for an extraordinary East-West partnership, our chances would be very good."

Black, Red, and Gold

The German Democratic Republic officially became part of the Federal Republic of Germany thirty years ago, reunifying East and West. In celebration of unity, Germans raised the black, red, and gold flag in front of the famous Reichstag building in Berlin.

German Flag

These colors date back over two centuries to the Wars of Liberation. The black, red, and gold striped German flag we know today made its debut shortly thereafter in 1832.

To commemorate the 30th anniversary of German reunification, the U1 DE Limited Edition was fitted with a black case, red markers on the bezel, and a special gold-plated seconds hand.

The dial is further distinguished from the standard Sinn U1 with the inclusion of "U1 DE" between the center post and 6.

Additionally, the caseback features a prominent SUG engraving along with the limited edition number.

A Familiar Design

Like the Sinn U1s before it, the Sinn U1 DE Limited Edition features the same great case design made in-house from German submarine steel at SUG. Once the case is complete, the Tegimenting process begins.  The case, crown, bezel, case back, bracelet and even the anti-reflective coating are hardened using Sinn's Tegiment technology.

Tegimenting the submarine steel along with a PVD application results in an exceptionally hard watch case with a rating of 2,000 Vickers, more than nine times harder than standard stainless steel.

And unlike watches made in stainless steel, this watch case does not need to be rinsed with tap water following exposure to salt water since it is made from true submarine steel which is corrosion resistant.

The matte black dial is surrounded by the U1's distinct block-shaped hour markers. The matching hour and minute hands complete the look.

The gold plated seconds hand of the Sinn U1 DE Limited Edition definitely "pops" and makes this watch a truly special piece.

Designed for Depth - 1,000 Meters

This watch features a uni-directional ratchet operated rotating bezel, which is also milled from the same submarine steel as the case. The bezel is also Tegimented along with a PVD application. The indices are machined directly into the bezel without the use of bezel inserts, which can corrode or come loose at deep depths. 

The international testing lab of Germanischen Lloyd has tested the Sinn U1 DE Limited Edition and determined that the watch can be certified as water resistant to 1,000 meters. This same firm tests submarines for their ability to withstand the effects of underwater use.

Other features of this watch include:
  • Fully Tegimented case, bezel and bracelet
  • Black PVD finish
  • Special gold plated seconds hand
  • SUG Glashutte engraving on case back
  • Screw down crown at 4 to reduce pressure on back of hand
  • Water resistant to 1,000 meters
  • Sapphire crystal with double AR coating
  • Low pressure resistant
  • Date display at 3

This watch is fitted with a fully Tegimented black PVD Sinn bracelet with black Tegimented locking clasp.

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.

Representative Timepiece of Germany

"Representative Timepiece of Germany"

Verified Owner Comments: I lived in Germany for several years and wanted a watch that would help remind me of those times when I look towards my wrist to check the time. This watch does just that. The antireflective coating makes it look as though the watch doesn't even have a crystal, allowing me an unobstructed view to the well-balanced dial and the gold plated seconds hand moving effortlessly around. The photos really don't do the seconds hand justice. It's polished to a high shine and looks absolutely amazing against the black dial. It's probably my favorite detail about the watch. The watch has some weight to it, which I prefer to titanium and carbonox watches. I also like how strong it is (fully tegimented), allowing me not to worry about scratching up my timepiece. If there was one thing I dislike about the watch, it's the action of the bezel, but that's being a bit picky, as the bezel is still pretty good. Obviously I'm quite happy with my purchase and will enjoy having this watch in my collection ... - more details

This Watch Is Me

"This Watch Is Me"

Verified Owner Comments: Where to start? Had been looking at purchasing a Swiss watch as an early retirement gift when my watch savvy Son pointed out that Germany has some good watch makers as well. Why did Germany get my attention? The Lady I've been dating for several years left East Berlin a few months before the Wall came down. Fast forward to today. When I saw the U1 in the DE Edition, I knew I had to get this watch. Not to mention it has all I need. Time, date and a rotating bezel. Perfect form and function. The fit and finish is what you would expect in the way of German Engineering. Excellence! The online videos and pictures don't do the gold second hand justice, and the sapphire crystal looks as if it's missing when looking directly at the watch face. The added bonus of DNV-GL Certification of Sinn's processes carries additional credibility with me, as I'm employed by a US counterpart. I'm not a diver, but neither am I a pilot or race car driver. But this watch, I can use daily, and not feel like ... - more details
