See how the setting lever and yoke work together when you pull the crown to change between winding and hand-setting.
Pulling the crown moves the **setting lever**. The lever then shifts the **yoke**. The yoke moves the **sliding pinion** into winding or setting engagement.
This is a simplified educational diagram. Real keyless-works geometries vary by calibre.
What does the setting lever do? It responds to crown pull and starts the shift into winding or setting functions.
What does the yoke do? It transfers the lever’s motion to the sliding pinion so the correct gear path engages.
Why are crown positions mushy? Wear, dirt or damage in the lever/yoke/keyless chain is a common cause.
Can this affect hand-setting only? Yes. Some faults show mainly in setting engagement, while winding still feels acceptable.
