Abstract

A mechanical digital watch comprises a continuously rotating minute disc having the numerals 0 through 59 positioned consecutively about the periphery thereof and an hour disc having the hour numerals thereon which is driven by a cannon pinion through a Geneva drive pinion arrangement. The hour disc is stationary during approximately 54 minutes of each hour and rapidly shifts to the next digit between 3 minutes before each hour to 3 minutes past each hour. The time indicating discs are in gear engagement with each other which prevents them from falling out of synchronism with each other under shock.
