Abstract

The time-setting mechanism comprises a shaft 112 rotatably mounted in a tube 114 in the back 6 of the watch case. The inner end of the shaft is provided with a mutilated gear 118 formed with a recess 118a. The outer end is provided with an operating blade 116 mounted for pivotal movement about the axis X1, X1 by means of swivel pins 122, 122'. The outer surface 6a of the back 6 contains a seating 126 in which the blade can be held stationary in a folded back position. The gear 118 can mesh with a time-setting adjusting wheel 22 of the going train. When the blade is positioned in its seating, the shaft is in a datum position and the recess 118c of the gear 118 is opposite the adjusting wheel 22, thereby ensuring the disengagement of these two parts. In modified embodiments, the shaft 112 can be pulled out against a bias spring to disengage the gear 118 from the adjusting wheel 22, either for free return to the datum position or to bring into mesh with the wheel 22 a fully toothed wheel which turns the hands more rapidly. <IMAGE>
