Conceived as an extremely functional pilot’s watch, the EZM 3F was just introduced at Baselworld 2015, becoming the latest addition to the series of no-nonsense watches originally developed for elite police units.

An variation of the EZM 3 diver’s watch, the EZM 3F (the suffix stands for flieger) offers a cleaner dial and more discrete date window, while preserving the trademark military look of the EZM watches. Naturally it is also endowed with the Sinn‘s inventions conceived for tool watches, like an integrated dehumidifier. The watch that started the series was the EZM 1, developed in the nineties for the German customs service commandos. EZM stands for einsatz zeitmesser, or “mission timer”. Like the original EZM 1, the new EZM 3F has its crown on the left of the case, originally conceived to prevent it from pressing into the wrist when handling a gun.

The EZM 3F has a 41 mm steel case filled with Argon to keep moisture out (hence the “Ar” logo on the dial), and fitted with a copper sulphate capsule (visible on the lug below) to absorb any moisture that does get in. Both the case back and crown are screw down, for a water resistance of 200 m. 

Because the escapement is lubricated with Sinn’s own oils designed for temperature resistance, the watch is guaranteed to function between temperatures of –45 °C and +80 °C. And an inner soft iron cage protects the movement (an ETA 2824) from magnetic fields of up to 80,000 A/m.

Pricing starts at €1490 for the EZM 3F on a leather or silicone strap, while the steel bracelet model costs €1625.
