The Sinn EZM 1.1 Mission Timer

This Over-Engineered Chronograph Is Sinn’s Latest Watch

September 1, 2017 Watches By

In 1997, German watchmaker Sinn partnered with the German government to create the EZM 1, a rugged titanium chronograph used by the German Zentrale Unterstützungsgruppe Zoll (ZUZ) special police force. The watch came to define future EZM models by Sinn, and has since become a sought-after timepiece for collectors. Now, there’s successor to the iconic watch, the limited edition EZM 1.1.

The EZM 1.1 retains the original EZM 1’s simplified dial layout with the chronograph seconds and minutes displayed on the whole watch dial rather than through the sub-dials you’d see on a standard chronograph. There are some fairly big changes too. For starters, the case is now made from “TEGIMENT” steel rather than titanium, and the EZM 1’s Lemania 5100 movement has been swapped for a modified Valjoux 7750. The case size has also been upped from 40mm to 43mm.

This being a Sinn, the EZM 1.1 is absurdly over-engineered. For example, the case is filled with nitrogen (Sinn used to use argon, hence the “Ar” on the dial) to keep the crystal from fogging up on the inside. It’s also water resistant to 200 meters and apparently operates properly at temperatures between -49º and 176º Fahrenheit. Only 500 EZM 1.1s will be made and they’re currently available for pre-order now.
