How It Works

The size and shape of an ordinary pocket watch, the chronodrometer has a distinctive dial. The center hand circles the dial once in four minutes. The smaller hand at the bottom of the dial circles once in four seconds and, at each beat of the watch, marks a quarter second. At the top is a dial to indicate ordinary time of day. To use the watch, the user pushes a button on the side of the watch, which causes both the center-seconds hand and the 1/4-seconds hand to fly to zero. A second push on the button starts the watch, a third stops it. Not only does it stop the hands, it stops the entire movement of the watch.
