<p>The movement, of conventional type with barrel (10) and hairspring balance, includes two time displays with hands, one of the displays having its hands (3m, 3h, 3s) arranged opposite one of the main faces (1) of the movement and driven round in a known manner by a gear train comprising a toothed centre wheel (12) fixed on an arbor (13) together with a pinion (11) meshing with the barrel. Opposite the other main face (2) is another time display whose hands (5m, 5h) are driven by another gear train (35, 36, 37, 38, 39, 40, 41), a toothed wheel (35) of which is fixed on the arbor (13) of the centre wheel (12). This arrangement makes it possible to minimise the height of the other gear train, and to guarantee the same small shake to the hands of both displays. The spring of the barrel (10) is tightened with an automatic winding device comprising an oscillating mass (7) arranged opposite the other main face (2) of the movement. A time-setting stem (6) which can occupy a neutral axial position and two pulled-out positions, makes it possible, in cooperation with a transmission mechanism (47-56), to correct the indications of one of the displays in one pulled-out position, and the indications of the other display in the other pulled-out position. <IMAGE></p> |
