The Chronomaster Sport 03.3100.3600/69.M3100, seen from the bench
The Zenith Chronomaster Sport 03.3100.3600/69.M3100 combines a legendary watchmaking heritage with contemporary design. Powered by the El Primero 3600 automatic caliber oscillating at 36,000 semi-oscillations per hour, it features a 41mm stainless steel and ceramic case with contrasting two-tone finish. The 20mm lug width accommodates the proportional balance between case size and strap integration, designed to distribute wrist movement without mechanical stress. A chronograph with hours, minutes, small seconds, date, and vertical column wheel complication exemplifies Swiss engineering precision.
