Abstract

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.
