Zenith Chronomaster Open

The Chronomaster Open (Ref. 03.3300.3604/21.M3300) presents an unobstructed view of the watch’s high-precision beating heart, which Zenith accurately fits into the 39.5-millimeter stainless-steel case. With its transparent counter for the running seconds, the self-winding 1/10th of a second chronograph movement El Primero 3604 characterizes this version not only with technical sophistication, but also with a fascinating visual appearance. Further complications such as the 60-minute counter and the 60-second counter find their place in the overlapping totalizers, which are designed in the brand’s colors, as is typical for Zenith. The matte black dial with a date display between four and five o’clock and an outer scale for the precise measurement of tenths of a second harmonizes perfectly with this. An ergonomically designed stainless-steel bracelet, water resistance of up to 100 meters and a power reserve of up to 60 hours make this watch, which is equally suitable for men and women, a reliable everyday companion.
