Patent ID: 7027361

Claim:
A timepiece comprising a date display, wherein the timepiece comprises: a date display assembly comprising: a date ring having a plurality of digits thereon; a first gearing assembly comprising one or more wheels, being meshingly coupled to the date ring so that the rotation of the one or more wheels causes the rotation of the date ring; and a stepping motor comprising a rotor, wherein the rotor of the stepping motor is rotatably coupled to the at least one or more wheels of the first gearing assembly, wherein the rotation of the rotor causes the date ring to rotate; a date-keeping assembly operatively coupled to the date display assembly, comprising: at least a second gearing assembly comprising at least an hour wheel and a detection wheel assembly operatively coupled by rotation to the hour wheel; a spring assembly comprising at least three deflectable fingers; and wherein the detection wheel assembly comprises a first tab, a second tab and a third tab, wherein each tab is positioned such that: only the first tab is contactable with the first finger; only the second tab is contactable with the second finger; and only the third tab is contactable with the third finger; wherein at least certain rotational increments of the detection wheel assembly, and the clockwise or counterclockwise direction thereof, causes the rotor of the stepping motor to rotate so that the date ring can be rotated in one of a clockwise or counterclockwise direction; whereby the rotation of the hour wheel through a predetermined midnight position results in that the stepping motor causes the date ring to rotate a predetermined number of degrees, thereby advancing either in the forward or backward direction a displayed digit on the date ring.
