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 brand new 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.
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 9 TESTAF was tested and certified to the "Technical Standard for Pilot's Watches" (TESTAF) by the Aachen University of Applied Sciences.
This establishes the Sinn EZM 9 TESTAF as being suitable for professional use as a pilot's watch, and is thus tested and certified to the new Technical Standard for Pilot's Watches (TESTAF). As such, each watch will feature the "TESTAF" quality seal on the dial and 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.
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
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.
