Chronomaster Open 39.5 mm, stainless steel with black rubber strap, self-winding manufacture caliber El Primero with chronograph function | Reference Number ZN000007

The Zenith Chronomaster Open (Ref. 03.3300.3604/21.C822) presents an unobstructed view of the watch’s high-precision beating heart, which the manufacture 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. The matte black dial with and an outer scale for the precise measurement of tenths of a second harmonizes perfectly with this. An equally black cordura-effect rubber strap, a 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.
