ABSTRACT:
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.
