Abstract

The watch comprises an oscillator, a frequency divider, display means capable of displaying at least hours and minutes, and a correction circuit controlled by a rotary time setting stem which is capable of assuming at least two axial positions, one being a rest position which is occupied by the stem when the watch is functioning normally and an operative position for jointly correcting the minutes display and the hours display. The correction circuit is so arranged as to provide for correction of hours display alone in response to a particular rotary movement of the stem in its rest position. This particular rotary movement may comprise, in regard to the stem, rotating at least through a minimum angle in a time interval which is less than a predetermined period, for example at least two revolutions in less than two seconds. The minutes and hours displays are changed and the hours display is corrected in the forward direction or the backward direction depending on the direction of rotation of the stem.
