EZM 13.1 Bracelet

When it comes to its features, this diving chronograph is one of the most traditional and yet technically advanced timekeeping instruments.

The EZM 13.1 thus knows exactly what matters during use: a focus on the key essentials in terms of outstanding readability. To this end, we have integrated a factory modification with high functional value into the SINN chronograph movement SZ02. 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 (generally customary) 30-minute counter. It is distinguished by an optimised dial design. To enable clearer readability, the Arabic numerals have been omitted on the EZM 13.1. This adds an optical enhancement to its technically functional focus.

For the highest levels of mechanical stability and durability against external influences, we have equipped the EZM 13.1 with a technology package consisting of Magnetic Field Protection, Ar-Dehumidifying Technology and Temperature Resistance Technology. The independent classification company DNV verifies and certifies the water resistance and pressure resistance of the EZM 13.1 as well as its functionality in accordance with the European diving equipment standards.

Conclusion: The EZM 13.1 is primed and ready for its first use on your wrist!
