Sinn EZM 13.1


Sinn EZM 13.1
Model: 613.011

The diving chronograph with 60-minute stopwatch display

The return of a fan fave… when it comes to features, this diving chronograph is one of the most traditional and yet technically advanced timekeeping instruments in Sinn’s collection.

With a focus on the key essentials in terms of outstanding readability, this watch delivers astounding functionality and endurance in the field. To ensure robustness and precision, Sinn has integrated a factory modification of a high functional value into its chronograph movement SZ02. Furthermore, to enable the elapsed times to be read quickly and intuitively, the EZM 13.1 features a 60-minute counter at 6 o‘clock instead of a customary 30-minute counter which usually fills this space. You will notice the Arabic numerals have been omitted on the EZM 13.1, lending an optical enhancement to the technically focus of this piece. Finally, for the highest levels of mechanical stability and durability against external influences, Sinn has equipped the EZM 13.1 with a technology package consisting of Magnetic Field Protection, Ar-Dehumidifying Technology and Temperature Resistance Technology. Attesting to the quality and attention-to-detail built in to the EZM 13.1, the independent classification company DNV has verified and certified the water resistance and pressure resistance as well as the watch’s functionality in accordance with the European diving equipment standards.

Conclusion: The EZM 13.1 is primed and ready for use so, bring it on!

• Sinn chronograph movement SZ02 with a 60-minute stopwatch display
• Tested based on European diving equipment standards and certified by DNV
• Water-resistant and pressure-resistant up to a diving depth of 500 m (= 50 bar)
