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.

Abstract: In an electronic watch the indication of the time (hours, minutes and possibly seconds) is given in analog form by means of a first passive electro-optic display cell. The display segments of this first display cell are arranged radially with respect to a central point, and the activated segments thereof have the appearance of the conventional hands of an analog watch. The watch comprises a second passive electro-optic display cell furnishing information in digital form, for example indicating the day of the week and the date. So that only the second cell need be provided with an illuminating device, the watch comprises a selector which is manually operable by means of a push-button which, when it is operated, causes the time to be displayed by the second cell at the same time as the illuminating device thereof is operated. This arrangement enables the user to know the time in the dark without it being necessary to provide the first cell with an illuminating device.

Abstract: An electronic watch comprises two passive electro-optic display devices one of which provides a digital display and the other of which provides an analog display. In one operational mode, the analog display device displays the local time while the digital display device furnishes other information such as the days of the week and the dates, for example. In another operational mode, which is selected by means of a push-button, the analog display device comprises only one activated segment (constituted or formed of a ray) which is consequently visible, to indicate opposite a scale of the time zones which time zone is actually selected, the digital display device then indicating the time of the selected time zone. The selection of the time zone which is displayed by the digital display device is effected by means of another push-button.

Abstract: Electronic watch comprising electronic circuits provided for the measurement and the display of the time which are also partly used in order to provide a sequence of different states of the indication of an additional display circuit, an additional control circuit being controlled by a player in such a way as to interrupt the sequence of different states as a function of the instantaneous state of the additional display and of the adroitness of the player.

Abstract: Electronic timepiece with a device for indicating the time, which is electronically controlled and is used to display elements which simulate a game of chance. Additional circuits are provided for the control of the display of the elements of the game and at least part of the circuits of the timepiece, normally intended for the measure of the time are used in order to perform the choice at random of the elements.

Abstract: An electronic watch circuits for the measurement and the display of time and for measuring a reaction time, and which further includes circuits controlling the display of a signal determined by comparing the measured reaction time with a reference time.
