Abstract

The watch comprises a twelve-tooth pinion (13) driven by the month star (3) and making one revolution in one year. This pinion (13) drives a toothed wheel (20) coaxial with the month star and solid with a disc (21) or with a hand indicating the months. An indication of whether or not the current year is a leap year is given either by a disc (25) mounted directly on the hub (22) of the month star and visible through a window (26) or indirectly via the additional pinion (13) and a toothed disc or a piped wheel coaxial with the month star. <IMAGE>
