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.

Abstract: An electric timepiece has a metallic grid cut from a sheet of metallic material with portions of the grid utilized for connecting the electronic circuit and other portions of the grid utilized for mechanical elements of the timepiece movement. Plastic material is overmoulded on the metallic grid to support the electronic circuit. An element of the frame of movement of the timepiece is formed by a second overmoulding of the overmoulded metallic grid.

Abstract: An electronic timepiece includes an oscillating circuit for operating the timepiece. The oscillating circuit includes a capacitor having a value which determines the frequency of the oscillator and therefore the timepiece timing. The capacitor is removable and replaceable for repairing or adjusting the timepiece timing operation.
