ABSTRACT:
The fifth or intermediate wheel and pinion assembly of a gear train cooperates directly with the motor rotor pinion and the fourth wheel to provide a full stepdown in angular rotation between the motor rotor and a second hand. The upper tenon of the fourth wheel and pinion is supported on a third wheel bridge, and the upper tenon of the fifth wheel and pinion is supported on a fifth wheel bridge with the fifth wheel overlapping the tenon of the fourth wheel and pinion. This overlapping and elimination of wheels provides a compact, reliable and durable gear train for a timepiece of reduced dimensions.
