A late-1950s Zenith presented in a generous 37mm jumbo case, this watch reflects the restrained proportions and clean surfaces of 1959-era design. Its construction centers on the distinctive automatic bumper mechanism, driven by Zenith’s Cal. 133.8, a movement that illustrates the brand’s mid-century expertise in self-winding systems. Recently fully serviced, the watch offers the tactile character and mechanical engagement collectors appreciate from bumper automatics. For someone building a collection focused on historic movements and period-correct proportions, this Zenith represents a thoughtful example of mid-century watchmaking craft.
