Sinn EZM 9 TESTAF

There have been mission timers for different purposes, like diving, flying and border control (like the illustrious GSG 9 models). However the design and construction demands were mostly determined by Sinn them selves, probably supplemented by a third party who had special interest in a certain EZM watch for their specific use, or certain DIN or ISO specifications. Now however two EZM models were constructed and designed additionally by the (relatively new, 2012) technical standard for pilots watches, http://www.watchgoing.com/rolex-c-63.html TESTAF. We had the pleasure to receive one of them, the Sinn EZM 9 for an extensive review.

First something on the TESTAF certification. TESTAF was developed by the Technical University of Aachen in Germany, in close cooperation with several companies in the aviation and watch industry. This certification determines the regulations wrist-pilot watches with analogue time display have to fulfill in the civil air traffic in regard to visual- (VFR) and instrument- (IFR) flight rules.

The most significant requirements, or at least the ones who influence the design and construction of a TESTAF certified pilot watch the most, are in the following fields: not interfering with the operation if the aircraft; not being affected by the physical stress of regular flying or by unexpected malfunctioning of the aircraft; the ability to operate as the primary time measurement instrument to enable the pilot to plan and execute any necessary time-related flight manoeuvres.
