ABSTRACT:
A calendar mechanism for a timepiece having indicators for the day of the month and for the day of the week, in which the indicators are held in each position by a locking lever pivotally mounted for movement between operative and inoperative position with respect to the indicators. The locking lever has two integral arms, one cooperating with each of the indicators for locking and releasing them. The driving member which indexes the indicators once every twenty-four hours is provided with means for urging the locking lever into its operative position at all times except when the indicators are being indexed to new positions, so that the indicators remain in place when they are not being driven but can be independently reset at any time.
