Sinn EZM 10 Tegimented Titanium TESTAF DIAPAL
Product Details


Prepare to be blown away - this watch is Sinn's crowning achievement and features a movement so advanced that only a very small number are built each month.

As we have traveled the country showing the Sinn Collection through our Road Shows, the Sinn TESTAF Certified Professional Pilot's Series has stood out in every city.


Background

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 exist for example for diver's watches.

Many watch brands classify their watches as "professional pilot's watches", but Mr. Schmidt knew that this was a hollow phrase that had absolutely no substance behind it.

He set out on a journey to encourage the independent development of a set of standards to which a watch must conform to be classified a certified pilots watch, and TESTAF was born.

Mr. Schmidt recently spoke with us and indicated that DIN will adopt the standards set by TESTAF for professional pilots watches. He expects this action to be taken in the next few years at which time there will no longer be confusion about what is a true certified professional pilots watch.

The new Sinn EZM 10 TESTAF DIAPAL was tested and certified to the "Technical Standard for Pilot's Watches" (TESTAF) by the Aachen University of Applied Sciences.

This establishes its suitability for professional use as a pilot's watch, and includes a certificate and the "TESTAF" quality seal on the dial.


Summary of Technologies

The range of technologies also includes Sinn's Dry Hold technology for greater functional reliability and freedom from fogging and overall functional reliability at temperatures between 45 C and + 80 C.

Take a look at these specs, and we think you will agree this watch sets a new standard for pilot's watches:
  • Tested and certified to the Technical Standard for Pilot's Watches (TESTAF) by the Aachen University of Applied Sciences
  • Sinn SZ-01 calibre
  • Centrally mounted elapsed chronograph hand
  • Case made in-house of Tegimented titanium by Sinn's case manufacture in Glashutte, Germany
  • Dehumidifying technology enhances functional reliability and freedom from fogging
  • Functionally reliable from 45 C up to + 80 C
  • Captive pilot's bezel with minute ratcheting
  • Sapphire crystal glass
  • Water resistant to 200 meters
  • Low pressure resistant
  • DIAPAL oil free escapement with nano-technology
  • Flush chronograph pusher mounts
  • Dual color SuperLuminova
  • 5 year limited manufacturer's warranty

Additional Background

The Sinn EZM 10 TESTAF is the first watch worldwide that been tested and certified to the new Technical Standard for Pilot's Watches (TESTAF). Each watch will be shipped with a special signed certificate indicating that this watch bears a serial number which is within the range of those watches approved by TESTAF.

However, Sinn didn't want to make just a pilot's watch. They also wanted to make the most technologically advanced Mission Timer (EZM) to date, by including an extensive range of additional features.

To start, at the heart of this chronograph is the all new Sinn SZ-01 movement, which features a center-mounted 60 second stopwatch hand. 

This special technical feature yields two bene?ts: ?rst, 60 minutes are now counted in one sweep of the hand instead of the usual 30 minutes, and second, the minute stop scale covers the entire diameter of the dial meaning that the measured times can be read off immediately. 

Additionally, the chronograph hands are luminous, and thus perfectly visible even in the dark. This function is complemented by an all-new minute-ratcheting sapphire pilot's bezel, which allows for the numerals indices and main maker to all be lumed.


Tegimented Titanium - A First

Also in use for the first time is a fully-tegimented case made entirely of high-strength titanium at Sinn's case making manufacture in Glashutte, Germany. The Tegiment process, Sinn's patented case-hardening technology, was previously available only to those watches which featured a stainless steel case, which is quite heavy in comparison to titanium. 

As a large watch, the Sinn EZM 10 TESTAF would need to be light enough for daily wear, yet also tough enough to resist scratching in an often cramped and busy cockpit environment, and thus the process to Tegiment titanium was invented.

This is the only such watch in Sinn's current production to feature Tegimented titanium.

The watch is water resistant to 200 meters, and features a black calf-leather strap with water-resistant backing and orange stitching. 


DIAPAL Escapement

This new watch features the very latest construction of Sinn's patented DIAPAL oil free escapement.

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, "Diamantpaletten”) 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.



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: Great watch, highly functional and very understated (for a large titanium watch).

Perhaps the best tool watch on the market, and certainly the best priced. The titanium case and band are very scratch resistant, the sapphire bezel is highly readable and also scratch resistant, and the central minute hand makes this the most legible chrono available.

Comments about this watch: A perfect work watch.

As large as it is, it comes in at only 117 grams. That is as light as my Rolex GMT master which is less than 1/2 the size.

The best thing about the purchase was the great customer service and how easy it is to get a knowledgeable person on the phone before and after making the purchase.

This company Rocks!

Comments about this watch: It's been a pleasure doing business with WatchBuys - customer service is outstanding.

As for the watch, I like it a lot. Has the in your face look that got my attention. Plus the Sinn quality. Having said that, I do think that the watch is over priced. For that kind of money it should have included the bracelet. All and all I'm happy with the watch, it's all that you would expect from the Sinn line up.

Comments about this watch: This is one great looking watch!

It's imposing, but surprisingly light thanks to the Titanium construction. The black leather band with the orange stitching is very sturdy and makes this watch pop even more. The regular size for the wristband was too small, but WatchBuys had a long version readily available and that fit perfectly.

Comments about this watch: Sticker shock!  That's the first thing you'll feel when you encounter this timepiece. You'll realize that you're getting into Omega territory, and may even be tempted to go there. Don't go there! There is nothing else like it, and its well worth the price.  Why? This chronograph is the most legible, usable timer I have ever owned.  The centrally mounted orange second and minute hands make reading the chronograph as easy as telling the time. Moreover, everything on this watch is color coded; orange for chronograph, white for time. Make no mistake, this is a real chronograph, not just a sporty adornment you'll never use. It may look complicated, but it's really simple, and within a day it will feel like an extension of your mind.  The titanium case is perfectly tapered, and very light relative to the size of the watch, making it extremely comfortable and easy to wear.  Granted, with a watch like this, you'll know you have it on. But it feels great. The crown is e... - 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.

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.
