Abstract: The invention relates to a setting method of the perpetual calendar of a chronograph watch having an analogic display and comprising a watch case, a time setting stem and two chronograph pushers. The display comprises a dial provided with an hour and a minute graduation as well as a centered chronograph hand and eccentric chronograph counters for the minutes and the hours each presenting a graduation, a corresponding hand and a date display. The watch comprises at least a driving motor for these hands and an electronic circuit provided with a processor controlled by a quartz time base. The setting of the perpetual calendar, number of the years within a cycle of four years, number of the months of the year, and indication of the date is controlled by the time setting stem and the two chronograph pushers. During the setting process, one displays the value of each of the parameters to be set successively by one of the hands and of the corresponding graduation.
