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.
A double faced watch having first and second dials on opposite sides thereof and first and second hand displays overlying said first and second dials, respectively, first and second gearing for setting said first and second hands arrays, a rotatable setting stem slidable axially between a first position in which rotation of said setting stem actuates said first gearing to set said first hands array and a second position in which rotation of said setting stem does not move said first gearing, a rotatable member slidable in a direction parallel to said setting stem between a first position in which rotation of said member actuates said second gearing to set said second hands array and a second position in which rotation of said member does not move said second gearing, means to rotate said member, and a lever pivotally interconnecting said stem and said member for movement in opposite axial directions such that when said stem is in its respective first and second positions said member is in its respective second and first positions.
