<p>The timepiece has a digital display mechanism with four drums cinematically connected to each other. Two of the drums display minutes and hours by a scale and a scale graduation, respectively, and the third drum displays tens of minutes. The fourth drum displays tens of hours by a scale (0-1-2). One drum (416) has a differential mechanism (504) interacting with an input pinion (506) carried by the fourth drum so that the drum (416) is enabled to move forward to one division per hour in normal time and to pass from a division 3 to division 0 when the display passes from 23h59 to 00h00.</p> |
