A timepiece comprising a date display, comprising a date display assembly comprising a date ring, a first gearing assembly being meshingly coupled to the date ring for causing the rotation of the date ring; and a stepping motor comprising a rotor, wherein the rotor of the stepping motor is rotateably 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, wherein at least certain rotational increments of the detection wheel, 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 representing a valid date. Methodologies for setting and adjustment are also provided.

The mode selecting assembly comprises a flexible hand, coupled to a frame in the casing, that has extending therefrom fingers that are sufficiently deflectable so as to deflect from first positions where they are not in contact with associated pads on a circuit board to second positions where they are in contact with their associated pads on the circuit board. A setting stem comprises an annular ring for selectively contacting and deflecting the fingers from their respective first positions to second positions, wherein the integrated circuit is operable in a selected modes depending on which finger is in the second position.

Mode selecting assembly for a timepiece

A time adjustment assembly for a timepiece comprises a fast hour wheel that is movable between a first position where it is not rotationally engageable with the hour wheel and a second position where it is rotationally engageable with the hour wheel; a corrector wheel, mounted on the setting stem, for rotating the fast hour wheel; and a setting spring selectively engageable with the fast hour wheel to move the fast hour wheel between the fast hour wheel's first position and second position; wherein when the fast hour wheel is in rotational engagement with the hour wheel the setting stem is out of engagement with the setting wheel and an hour hand is movable independently of the minute hand via the rotation of the setting stem.

Setting assembly for an analog timepiece

The instant invention relates to a horological movement provided with shaft guide means. This movement has horometric means (H) capable of supplying a time information and at least one control member (34) composed of the shaft and adapted to act on the horometric means (H), this control member (34) being guided axially and/or in rotation by the intermediary of guide means, this movement also being characterized in that said guide means are composed of three guide pieces (38, 40, 42) mounted and maintained sandwiched on one another to form therebetween a seating in which the control member (34) is freely received.
