ABSTRACT:
A watch comprising at least a minute hand, an hour hand and a knobbed shaft which can occupy an extended axial position known as a correcting position.
Minute-by-minute correction or correction by whole time zones is operated with the knobbed shaft in the same extended position by the selection of the speed at which the knob is rotated. Time zone correction always uses as point of reference the real time at the moment of actuation of the knob into the extended position, and the watch includes means operative to cancel any step-by-step correction of the minute hand which may have preceded the time zone correction.
