ABSTRACT:
A double faced watch has a movement driving a first gearing actuating a first hands array cooperating with a first dial and a second dial 31 on its opposed face cooperating with a second hands array 32, 33', 43. An automatic winding mass 19 is pivoted concentrically to the two hands arrays by a bail bearing the internal housing of which is fastened on a sleeve giving passage to an axle 7, 7', carrying one hand of the first hands array. This axle 7, 7' is used as a driver for the driving of the second hands array. A time setting stem 55 is axially slidable between two positions, in one of which its rotation sets one of the hands arrays and in the other of which its rotation sets the other hands array. A tilting member 62 (FIG. 6) ensures that the setting stem 55 slides in the opposite direction from a sliding pinion 47 so that the stem 55 and pinion 47 are alternately in driving relation with one or the other of the drive trains of the two hands arrays.
