For sale is an excellent example of the Sinn EZM 1 Mission Timer Gen 1.
With a Titanium bead-blasted 40mm case and a black dial, it's fitted to an OEM titanium bracelet and deployant clasp. It was one of the first two models in Sinn's Einsatzzeitmesser (EZM) line, designed for specific mission requirements. The EZM 1 has a chronograph with a distinctive left-side crown and pushers, a centrally-mounted minute and second chronograph counter, and a countdown bezel.
It's powered by the Lemania 5100, an automatic movement with a power reserve of 48 hours. It has a water resistance of 300m.
Complete with original box & papers, this 2006 example was fully serviced in 2022 and was recently fully tested following a minor repair. It's in very good condition throughout with light signs of wear to the clasp. A video condition review is available upon request.
