Sinn EZM 3 S

Diving missions under extreme conditions push both people and equipment to the limit – and often beyond. In icy depths, under massive pressure, or in near-zero visibility, absolute reliability is essential. For these kinds of professional operations, we developed the EZM 3 S: a mechanical technology basis that embodies the very essence of a SINN watch like few others.

At first glance, the EZM 3 S makes a bold statement: the Black Hard Coating combined with TEGIMENT Technology – used for the first time in this model series – gives it a strikingly technical profile. The colour contrast also significantly improves the readability of the diver’s bezel.

The true SINN DNA is revealed inside the watch. Its high-end technological features offer maximum resistance and uncompromising functionality. Equipped with Magnetic Field Protection, Temperature Resistance Technology, and Ar-Dehumidifying Technology, the EZM 3 S delivers an impressive package of performance. The reduced mission timer design ensures perfect readability and time measurement – even in high-stress situations. Another clear sign of quality that earns the trust of professional divers: the EZM 3 S has been tested based on European diving equipment standards and has been certified by an independent institute. One thing is certain: you can rely on this watch – 100 percent.

DNV has confirmed and certified the pressure resistance of the EZM 3 S model to a diving depth of 500 metres, as well as its temperature resistance and performance in accordance with European diving equipment standards EN250 and EN14143.
