Abstract (en)
[origin: EP1916575A1] The mechanism has a date ring (10) with a lug (30) and teeth (32a, 32b), and a date wheel set (12) driving an intermediate wheel set (16) through a step when the date passes from the 30 to the 31 of the month. An annual wheel set (14) is meshed with the set (16). The date set drives the set (16) through another step when the date passes from the 31 to the 1st of the month for the months of 31 days. A month indicator ring (52) has an inner flank fitted with teeth cooperating with the intermediate set that rotates the month ring to the latter step.
