Template:File The EZM 3 Mission Timer is a dive watch by Sinn produced since 2001.


Sinn Mission Timers are watches uncompromisingly designed for function. Besides the ease of readability, attained by optical withdrawal of functions that are not directly required for the diving operation, such as date display or dial lettering, a lot of Sinn special technologies find application in this watch. So the EZM 3 Mission Timer is equipped with dehumidifying technology using copper sulphate capsule. Diffusing water molecules unavoidable in the watch are absorbed, whereby a dry microclimate is ensured. An argon fill additionally increases the protection against misting.

Furthermore, the watch can withstand harmful magnetic field influences up to 80,000 A/m and through an oil developed Sinn is functionally safe from -45°C to +80°C. Sinn lets check and certify the pressure relief and temperature resistance by the German Lloyd in Hamburg.

In 2015, Sinn introduced a pilot's watch version, the Sinn EZM 3F.
