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.
