Abstract:
A time adjustment assembly for a timepiece, wherein the timepiece comprises a casing, a setting stem displaceable in a plurality of axial positions and including a toothed ring thereon, a setting wheel that is selectively and rotatably engageable with the toothed ring on the setting stem, a center wheel that is rotatably engageable with the setting wheel, a minute wheel that is rotatably engageable with the center wheel, and an hour wheel that is rotatably engageable with the minute wheel, the time adjustment assembly comprising: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; 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, which is coupled to the hour wheel, is movable independently of the minute hand via the rotation of the setting stem.
