A universal watch wherein the hour hand may be corrected incrementally by an hour or less in response to the pushing, pulling or turning a stem or shaft.
A timepiece comprises a click device disposed between a first hour wheel and a second wheel carrying an hour hand. The first wheel is freely mounted on a shoulder of the second wheel and is held on the shoulder by a leaf spring secured to the second wheel. A boss or recess at the free end of the spring cooperates with one of twelve complementary recesses or bosses on the felloe of the first wheel to hold the first wheel in any one of 12 positions, whereby during use of the timepiece the hour hand can be made to jump by steps by 1 hour.
A battery-operated watch or clock has a knob which is axially shiftable been a first terminal position recessed in a rear housing wall and a second terminal position projecting therefrom. In the recessed position, in which the knob is manually rotatable upon removal of a battery cover surrounding same, its rotation resets both the minute and hour hands of the timepiece to enable its adjustment, especially upon a replacement of a spent battery. In the projecting position, such rotation only displaces the hour hand to facilitate a changeover between standard and daylight-saving time or an adjustment to a different time zone.
A time correcting device for a time signalling timepiece including a time striking construction having an hour wheel pipe onto which an hour hand is attachingly pushed and a rotation detector linked to the rotation of the hour wheel pipe to control signalling numbers of a time striking device, an hour wheel inserted onto the hour wheel pipe with clearance, a click disc formed on the either one of the hour wheel pipe or the rotation detector in the time striking construction or said hour wheel, and a click apparatus facing to the click disc and fixed to the either other one of the hour wheel pipe, the rotation detector or the hour wheel, whereby the click action between the click disc and the click apparatus enables the intermittent rotation between the hour wheel pipe and the hour wheel so that the direct time correction on the hour hand can be performed with separation from a minute hand.
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.
