During setting it is driven by the intermediate wheel in the keyless works and it turns both the cannon pinion and the hour wheel, moving the hands.

The success of SWCC depended upon the clocks being reliably wound every hour without failure. The hourly winding motor was the one element of the clock that was most likely to fail.
