Abstract (en)
[origin: WO2010146436A1] The invention relates to a watch comprising a digital display that includes a plurality of display discs (111, 121, 131) on which the digits (140) are distributed into three sets, i.e. a set (110) for minute units, a set (120) for tens, and a set (130) for hours, and a jump management control for enabling substantially instantaneous changes in the displayed digits. For each set, springs (8, 14, 19) are arranged in such a way that, in the operating state of the watch: the continuous rotation of the driving wheels (7, 13, 20) winds the springs on the stud side; on the collet side, each balance spring is prevented from rotating by means of locking indices (4, 10, 16) that also prevent the cage of each set from rotating; the sequential release of the cages or discs for the tens of minutes allows the discs of the sets to rotate due to the driving action of the corresponding balance spring.
