Diver Watch - EZM 13

Model EZM 13

The diving chronograph with a 60-second scale for the minute stop

The EZM 13 was designed as a mechanical timepiece for professional diving. As readability plays a crucial role when diving, the EZM 13 features an integrated SINN SZ02 chronograph movement. Boasting a 60-minute – rather than the standard 30-minute – counter at 6 o’clock, this SZ02 movement enables direct and easy reading of the minutes right through from 0 to 60.
Another special feature is the positioning of the crown and push-pieces on the left-hand side of the EZM 13. These ensure unlimited freedom of movement for the hand. Also worth highlighting are the technological features of the diving chronograph, i.e. Magnetic Field Protection, Ar-Dehumidifying Technology and Temperature Resistance Technology. These features ensure professional divers are equipped with a reliable and high-performing instrument.
The EZM 13’s suitability for professional use was tested by DNV GL who verified and certified ist pressure resistance to a diving depth of 500 metres and its temperature resistance and functionality in accordance with the European diving device standards.
