- To check the exact time simply press the pusher 76, and place the watch in a plane perpendicular to the ground with the "midi" of the dial up, in the standard position.
- To obtain another phase shift of the needles simply rotate the watch while keeping it in a perpendicular plane and releasing the pressure on the pusher 76.
- FIG. 9 Another variant of the second embodiment of the device according to the invention is shown in FIG. 9.
- the means for dephasing the hour hand and the minute hand namely the Differential gears, are the same as those used in the variant of Figure 7.
- the identical elements of these two variants are taken with the same references.
- the means for changing the position of the hour hand 51 and minute 52 comprise a wheel 80 carrying a star 81 with twelve branches, held in position by a jumper 82.
- the wheel 80 meshes with the transmission wheels 72 and 72 'cooperating with the differential gears 56, 56'.
- the star 81 is actuable by a rocker 84 pivoting about an axis 85.
- Said rocker 84 has at one end a spout arranged to cooperate with the star 81, and at the other end, a prominence forming a pusher 86, constituting a control means.
- a jumper 87 exerts a tension on the rocker 84 allowing its return to the standard position when the pusher 86 is released.
- a second latch also acting on the star 81 and operable by a second push.
- This second rocker is arranged so that one of the rockers rotates the star 81 clockwise and the other rocker rotates the star 81 in the counterclockwise direction.
- the phase shift of the hands can be done in the choice of clockwise and anti-clockwise.
- the operation of the device is similar to that of the variant of Figure 7, the action of the oscillating mass being replaced by the pulse on the star 81.
- a pulse on the star 81 causes the rotation of the wheel 80 and a rotation of the rings 64, 64 'to obtain a rotation and therefore a phase shift of the hour hands 51 and of minute 52 of 30 °.
- the pressure on the pusher 76 ceases, the star 81 becomes stationary again.
- the hour 51 and minute 52 hands are then out of phase with the standard display, which allows an original display of the time, different from the standard display.
- the needles continue to progress conventionally, the rings 64, 64 'being again immobile.
- a drive gear 88 meshing with the outer toothing of the ring 64 ', and integral with a drive wheel 89.
- Said wheel 89 meshes with an internal toothing d' a ring gear 90 integral with a dial (not shown) on which the hours appear.
