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 ProtectionAr-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 its pressure resistance to a diving depth of 500 metres and its temperature resistance and functionality in accordance with the European diving device standards.
