Abstract: A stop watch (FIG. 2) for use by runners. A strap is provided and the strap bars 56,57 are disposed at a high level while the back 61 of the watch case is concave or dished. Push-buttons or control pins 17, 18, and 19, for starting, stopping, and resetting the watch, are disposed parallel to the axis of the watch and are actuated by pressing in the axial direction with the finger. These features accommodate strapping the watch to the hand so that the watch fits comfortably in the palm of the hand which is a convenient location when worn by runners.
