Product Details

Designed as instruments for professional use, Sinn's TESTAF Certified pilot watches must satisfy extremely high reliability and performance requirements. The Sinn EZM 9 TESTAF features an in-house Glashutte made 44 mm case comprised entirely of fully Tegimented Grade 5 Titanium that offers exceptional hardness and provides a scratch resistant finish.

Additionally the hands are luminous and thus visible in dim light, and this function is complemented by an all-new minute-ratcheting sapphire covered pilot's bezel which allows for the numeral indices and primary marker to all be lumed.

The total package is a watch that is highly visible and well suited for the cockpit but also lightweight and tough enough for everyday wear.

The Sinn EZM 9 TESTAF takes its design and technological cues from the flagship Sinn EZM 10 TESTAF but is perfect for those who do not need or want a chronograph complication.

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
  • 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 to prevent sapphire crystal detachment at high altitudes
  • Dual color SuperLuminova
  • 3 year limited manufacturer's warranty

Tegimented Titanium

Another technological achievement is the 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 professionally certified pilot's watch, the Sinn EZM 9 TESTAF needs 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 by Sinn.

This is only the second watch in Sinn's current production to feature Tegimented titanium, the first being the Sinn EZM 10 TESTAF.

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

Sapphire Protected Bezel

Sinn introduced their new sapphire protected bezel with the Sinn EZM 10, and this feature has been incorporated into the design of the new Sinn EZM 9 TESTAF.  The bezel is completely encased and covered by a sapphire crystal to offer protection from abrasions and other wear.

WatchBuys is the official North American distributor for Sinn German 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%.

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).

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.

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.

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.

Sinn is proud to present a collection of certified professional pilot's watches that meet these new standards.

Great tool watch

"Great tool watch"

Verified Owner Comments: Phenomenal watch and solid movement. The technology is superior and worth the price.

No regrets

"No regrets"

Verified Owner Comments: This is my first Sinn and probably won’t be my last. The 44mm case works for my wrist size and the lightness if the titanium makes me forget I even have it on. Dial is super ledgible. And the orange stitching on the strap pulls the orange of the seconds hand in very nicely.

The lume blazes at night and is still faintly visible the next morning if you charge it with a bright flashlight the night before. I also bought the corresponding titanium bracelet and switch with the strap occasionally.

Matt was super helpful and knowledable. He mounted the case on the bracelet for me before shipping and provided the strap in the bracelet box. Highly recommended!

The best all around 3 hand watch

"The best all around 3 hand watch"

Verified Owner Comments: I recently purchased the EZM 9, after wearing my Sinn 104 for about a year. I love the 104, but this watch is operating at another level. You get almost all of the Sinn technology (no Diapal, unfortunately, but everything else). You can swim in hydraulic fluid with this watch as long as you do not go deeper than 200 meters. It is anti magnetic, high and low pressure resistant, the works.

Very clean dial and I love the sapphire covered bezel. I do not mind heavy watches and the lightness of the tegimented titanium case still surprises me. You probably need a diamond to scratch this case. All of this and it looks fantastic while keeping time as well as any COSC certified watch.

German engineering excellence at its best. I have a dozen other watches but my Sinn's are my go to watches. I love them.
