Abstract (en)
[origin: EP0502292A1] This watch includes a case, an hour-setting stem (11) and two chronograph buttons P1, P2, a dial provided with a graduation (1) in hours and minutes and a chronograph hand (4) at the centre as well as off-centred chronograph displays for the minutes (5, 6) and the hours (7, 8) each having a graduation and a hand. It furthermore includes at least one drive for driving these hands and an electronic circuit provided with a processor and controlled by a quartz time base and a calendar display (9, 10). This procedure is notable in that the initialisation of the perpetual calendar, index of years within a four-year cycle, index of the month within the year, and indication of the date are performed with the aid of the hour-setting stem (11) and of the two chronograph buttons P1, P2, and each of the parameters to be initialised is displayed in succession with the aid of the hand (4) and of the corresponding graduation (1). <IMAGE>
