Of great appeal, the present timepiece impresses with its large 39 mm. diameter and charismatic multiscale dial.

At a first glimpse, it appears to be a regular chronograph wristwatch with two pushers for starting/stopping/resetting the chronograph hand. However, in the 1930s Eberhard & Co. introduced their calibre 1600 or EB 1600, a slightly modified Valjoux 65 movement, with a rare column-wheel integrated single button chronograph mechanism. The upper push-button starts, stops, and resets the chronograph hand while the lower “pusher” is in fact a slide. When moved towards the crown it allows the chronograph hand to be stopped/started without resetting it while at the same time locking the chronograph button.
