Product Details

This is the ultimate diver's chronograph watch - the Sinn U1000 S (Schwarz - Black) EZM 6 Chronograph. 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 best selling Sinn U series of diver's watches. Initially released several 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 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.

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 in combination with the PVD coating has a hardness of more than 2,000 Vickers which is more than 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. This process increases the submarine steel's resistance to corrosion, as well as provides extreme protection from scratches and damage to 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 operation of the chronograph have also been tested to that depth with certification from the international testing lab Germanischen Lloyd.

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 have been tested at that depth is an achievement.


Inside the Case

What's inside this watch also shows how Sinn engineers watches like no other. The base movement is a top 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.

To counter the effects of moisture and humidity, Sinn has applied their "Dry Hold" technology to this model, consisting of four copper sulphate capsules and the use of inert gasses sealed within the case.


The Bezel - Lock and Push

This watch features a brand new bezel design from Sinn. First, the bezel is attached to the watch with screws rather than friction mounted. These screws prevent the bezel from becoming detached through accidental contact with other objects. Next, the bezel is locked in place and will turn only if downward pressure is applied. This "lock and push" system ensures that time sensitive events (such as dives) will be correctly measured.


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. This watch takes its place as the new Sinn EZM 6, and you'll notice that the crown and pushers have been relocated to the left side of the case as is typical for EZM watches.





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
  • Case constructed of submarine steel for superior resistance to corrosion and scratches
  • Double Viton® seals
  • Modified SZ-02 movement with redesigned 60 minute register
  • Four 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 hardened with Tegiment process
  • In house case construction from Sinn's affiliated company in Glashutte, Germany


This watch ships with a U Series style Sinn silicone black rubber strap with your choice of compact or standard buckle.




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%.

Comments about this watch: The best watch I have ever owned.

Extremely robust and functional, in my opinion it is far better than many Swiss watches costing twice as much.

What a great watch

"What a great watch"

Comments about this watch: My favorite watches were always my Rolexes and Panerais. Frankly, I only expected to wear this watch on the occasional weekend, and was drawn to it simply because it was a Sinn with incredible features. Well, I haven't been able to take it off for months!

This watch is stunning on the wrist. The pictures do not do it justice in the least.

Amazing Watch!

"Amazing Watch!"

Comments about this watch:

Was a little worried about the thickness but that ended the first time I put the watch on. It wears great and looks great.
 
Having a U1 I had high expectations on the quality and detail and was not dissapointed. Love the slightly domed crystal. The dial is striking much better than in pictures. pushers and crown look,work,and feel great. Can't wait for the PVD buckle as it looks a little incomplete with the bead blasted steel buckle it came with (will be sent free of charge when available) note: the rubber strap is not same as u1 it is more bulky at the lugs so it conforms to the u1000 the fit is great.
 
All in all very happy with this purchase (yes event though it's a pricey purchase, especially unseeen as in my case) Please Sinn nothing this great next year! I need to diversify a bit (U1000S, U1, Rolex Sub date, Pam 111)

Sinn EZM 6/ U 1000

Comments about this watch: This watch makes a powerful impression when you see it. It came in the typical Sinn box with a tool to change the strap.( I got the black version)   Photos don't do it justice.   It took me about 20 minutes to size the silicon strap, which by its dimensions, complements the watch and is very comfortable to wear. The crown and chronograph pushers all operate smoothly and the bezel clicks into place and stays there. I bought the watch for outdoors activities of all types and by its obviously solid build I have no doubt it will give excellent service in the field.   Sinn says in the IB that it could take up to 8 weeks to run in completely but mine as been spot on straight out of the box. I also ordered the 757 UTC Diapal and can't wait to use it too. I have the 756 and the 142 st (which gets a lot of wrist time on trips and the weekends) and can say that the U 1000 appears to top anything Sinn has done yet. It is a tool watch, no doubt, but its quality matches anything o... - 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 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.
