Abstract
An electromechanical calendar timepiece has a date display provided by two indicators carrying the 'units' and tens data, respectively. The motor which drives these indicators can rotate at a normal speed or at a considerably higher speed. The units data comprise two consecutive figures '1' intended to display, respectively, the unit of the thirty-first of the months having thirty-one days and the first of each month, and one or the other of which displays the units of the eleventh and twenty-first of each month. The motor rotates at said higher speed on the one hand at the end of the months having less than thirty-one days and on the other hand twice each month, i.e. each time the '1' of the units data is displayed at the beginning of the second and the third decades.
