Sinn Retirement -  Last Chance to Purchase This Watch!

Sinn has officially retired the U1000 series of watches and we have received our final shipment.

This is the ultimate diver's chronograph watch - the Sinn U1000 S (Schwarz - Black) EZM 6 Chronograph on bracelet. This watch is packed with so much technology that fitting it all on one page is difficult.

The Case

The Sinn U1000 S is of course part of the Sinn U series of diver's watches. Initially released fourteen years ago, this series is constructed from the same steel that is used on the outer hull of submarines. The steel was procured by Sinn from a steel supplier to Emden GmbH, one of Germany’s North Sea shipbuilding yards who construct submarines. This submarine steel is not only extraordinarily sea water resistant (PRE value up to 38), it also possesses the highest anti-magnetic quality.

Next, the Sinn U1000 S features a completely Tegimented case, pushers, bezel and crown. 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 on this watch has a hardness of 1,500 Vickers which is more than six times harder than standard steel.

The Tegiment layer is not a coating consisting of a foreign material, but instead the steel itself that has been hardened using a special engineering process that creates a hardened barrier. This process increases the submarine steel's resistance to corrosion, as well as provides extreme protection from scratches and damage to the case.

The Tegimenting process also acts to harden the black PVD treatment on the case.

Water Resistance

Next, a discussion of water resistance. This watch represents a breakthrough on the testing of chronograph functions at great depths. The watch is not only rated water resistant to 1,000 meters, the pushers and other chronograph functions have also been tested to that depth.

Sinn has developed a special system of double Viton® seals and other engineering processes to achieve this certification. While building a 1,000 meter dive watch is not in itself unique, building a diver's chronograph whose functions and pushers have been tested at that depth is a significant engineering achievement.

Inside the Case

What's inside this watch also shows how Sinn engineers watches like no other. The base movement is a highest grade Valjoux 7750 which Sinn has modified to create their SZ-02 calibre. The primary modifications consist of a redesigned minute register which actually counts 60 minutes rather than the typical 30. This register has been enlarged and is placed at 6, with the primary hour register located at 12.

Next, Sinn has used its special oil to construct the movement. The Sinn special oil, also known as Sinn 66-228, permits a greater range of operating temperatures from - 45º C to + 80º C - in other words, this watch will hold up in extreme conditions. To counter the affects of moisture and humidity, Sinn has applied their "Dry Hold" technology to this model, consisting of copper sulphate capsules and the use of inert gasses sealed within the case.

By adding these features, Sinn is able to extend the manufacturer's warranty from the standard two years to three years, and the recommended service disciplines (overhauls) are less frequent than on watches that do not contain this feature as the "Dry Hold" technologies protect the oils. 

EZM Design - EZM 6

Sinn is known for their professional special forces watches, called the Einsatzzeitmesser (EZM - in English "Mission Timer") series. Sinn has long been a supplier of watches to various divisions of the German special forces, including the GSG-9, border protection, customs, military and special police divisions. Designing watches for these units carries a number of requirements, including resistance to shocks, water, magnetism and temperature changes among others.

There is also a functional requirement in that the watch must be highly legible and the controls must be both accessible and easy to use in extreme environments.

The Bracelet

The Sinn U1000 S features an all new stainless steel bracelet which has been fully Tegimented, including the clasp. This process ensures that this bracelet will resist scratches and other surface damage, even in tough environments.

We know - this is a lot of information for one watch. But we feel it's important to understand what's behind a watch of this caliber. In summary, these are the points that make this watch stand out from what you are likely to see during your next visit to a watch retail store:

  • Full Tegiment construction - six times harder than standard steel watches
  • Last chance to purchase as this series has been retired
  • The black PVD treatment is also Tegimented, adding durability to this process
  • Case constructed of submarine steel for superior resistance to corrosion, scratches and magnetism
  • Double Viton® seals
  • Modified SZ-02 movement with redesigned 60 minute register
  • Sinn special oil for operation in extreme temperatures
  • Sinn copper sulphate capsules to absorb moisture and humidity
  • Inert gasses have been inserted into the case to promote a dry and stable environment
  • Bezel is screwed to the case using an exclusive Sinn design
  • Bezel is locked into position and will rotate only when pushed down
  • Built to the standards of the German special forces - EZM 6
  • Double coated anti-reflective sapphire crystal
  • In house case construction from Sinn's Glashutte case manufacture SUG

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 Mount Joy, 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.

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 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 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%.

U1000 is a Great Piece

"U1000 is a Great Piece"

Comments about this watch: I recently purchased a Sinn U1000 Black on Bracelet. I have worn a Sinn UX GSG9 On bracelet for almost 5 years. So far I love the U1000 black. It looks great it feels similar to the UX on the wrist, although it is a little taller. However, if you are used to wearing large watches the U1000 feels right at home. Everyone who has seen it complements the flat black finish and overall look of the watch. They also complements the weight and feel of this watch. I like to say Sinns are built like tanks! I love this piece and I made the right decision in buying it, and the staff at WatchBuys was very helpful and courteous. I also love that Sinn bracelets are end-user adjustable. I was able to adjust the bracelet without leaving my office. In closing I’d like to say that this watch is a great piece. I should have purchased it months ago, but better late than never. I love the flat black finish, the way it feels on the wrist, and the overall looks of the watch. I can’t help it but stare at it thr... - more details

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).

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.

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 existed 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.
