Digital Stop Clock

The world’s first quartz digital stop clock, developed for the Tokyo Olympics. It digitally measured lap times and elapsed times of up to 9 hours, 59 minutes, 59 seconds, and 99/100ths of a second. The innovative digital display was easier to read and eliminated misreads once and for all. Used for medium-to-long-distance races in track and field.
