Ratchet Wheel

Ratchet Wheel Example

On a mechanical movement, the ratchet wheel is located above the mainspring barrel. This wheel is attached to the barrel’s arbor via a single screw. It is responsible for transferring energy to wind/coil the mainspring. The energy is stored (power reserve) and released (time keeping). The stored energy is a result of either manually winding the movement via the crown, or from the spinning of the rotor on the automatic wind unit.

These are famous for failing in the Sellita sw movements I’ve had 1 Oris Aquis and 2 others with rotors gone bad on 2 years or less
