Yoke

The yoke is part of the keyless works in a watch movement and helps shift the sliding pinion between winding and hand-setting positions. It works together with the setting lever, stem, and clutch components to control crown functions. Yokes are commonly replaced when worn, bent, broken, or causing issues with winding, time-setting, or crown position changes.
