The Barrel

Reference no 182
 

  The Barrel (182) contains the Mainspring which constitute the power source of the watch, top and bottom sides as shown in the photos above.

The outer end of the Mainspring is fitted to the Barrel by some type of clever hook that engages a slot in the barrel circumference. The inner end of the main spring has a slot that fits to a hook at the Barrel Arbor (195). The bottom of the barrel is fixed to a wheel with teeth, or the barrel rim itself has teeth as in the picture. These teeth are connected to the wheel train.

To the left the squared fit of the Barrel Arbor (195) to the Ratchet Wheel (415) can be seen.

 
 
  In the picture the Mainspring in the Barrel (182) can be seen in its fully wound state.
