The Setting Wheel

Reference no 450
 

 

The Setting Wheel (450) is driven by the Clutch Wheel and transfers rotation to the hands when setting the watch.

 
 
 

When the winding stem is pulled out, into its hand-setting position, the Clutch Wheel will engage the Setting Wheel which in turn interacts with the Minute Wheel and hence the Hour Wheel and the hands. Because of the friction fit of the Cannon Pinion  to the Center Wheel arbor, the Minute Wheel and the Hour Wheel can rotate freely from the gear train when the hands are set by rotating the Setting Wheel

 
 

  The Motion Works are shown in the skeleton movement in the winding position. The Setting Wheel is disconnected and is able to rotate freely.
