Abstract
The timepiece of the invention includes a hand for date display. This hand is driven via a calendar ring of a well-known type bearing teeth on its outer circumference. Such teeth drive intermediate gearing which in turn drives a calendar wheel fixed to the date display hand. This mechanism enables the mounting of a date displaying hand on a movement normally intended to show dates through a dial opening with minimum modifications.
