Abstract

A. Description: a) a cambered toothed ring (1) of 31 more or less long and high slots are urged to replace the initial date ring; b) an 8-toothed star (10) topped with a disk (11) is used for indicating the tens of the month through an open window (16) in the dial (15); c) a 10-toothed star (7) topped with a disk (8) is used to indicate the units of the month through an open window (16) in the dial (15). d) a spring cam jumper (13) maintains the stars in position; e) a main plate (5) of the movement diameter is urged to be fixed on the watch movement to assemble together the whole set of said components. B. Function mode: a) the toothed ring (1) rotates completely in 31 days; b) the cambered slots of said ring drive each star forward by one tooth at a time; c) the stars co-operate with the ring each at a different level; d) when a slot is shorter or less high, it doe not drive the star and the latter stays put; e) such that the ring is programmed for the disks to indicate through the dial the days of the month from 1 to 31 and automatically shift from 31 to 1.
