Abstract

1410871 Watches A SCHILD SA 26 Jan 1973 [27 Jan 1972] 4162/73 Heading G3T In a watch movement with a barrel 13 extending close to the centre and driving an off-centre second wheel and pinion 14, a third wheel and pinion 16, 15a, and a central fourth wheel and pinion 12, 11, the wheel 19 of the second wheel and pinion being located between the barrel and a bridge 2 at the same level as the fourth wheel 12, and the third wheel 16 and fourth pinion 11 lying in a recess 20 in the bridge, an auxiliary pinion 22 frictionally coupled to the third wheel shaft 21 drives a centre wheel 8 which is attached to minutes cannon 5 and located against the outer face of a frame plate 1. A pinion toothing 7 of the cannon drives a minute wheel and pinion (not shown), and thus the hour wheel 6. The fourth wheel 12 is fixed to seconds hand shaft 10 and drives an escape wheel pinion 18. A frame part 27 carrying a pivot stud 26 for an automatic winding mechanism is fixed to the bridge 2 by a pin 35 and a screw (not shown), adjacent a step 28 in the bridge. A further frame part 31 which supports winding mechanism reverser wheels is fixed to the part 27 by screw(s) 32 which are recessed in the bridge.
