This is a genuine Omega setting lever for Caliber 9300 automatic chronograph movement, part number 7229300A5108018, Swiss‑made. The setting lever is a key component of the keyless works, working with the setting lever jumper to control crown positions (winding, time setting, quick‑set date), ensuring clear and stable crown operation. When the original setting lever becomes worn, deformed, or broken, causing abnormal mode switching, replacing it with this genuine part is the best choice to restore proper keyless feel.
Genuine Omega Part – Swiss factory‑original for Caliber 9300, not a copy.
Keyless Works Core – Works with the setting lever jumper to control crown positions (winding, setting, quick‑set date).
Precision Manufactured – Accurately machined lever geometry for crisp, smooth operation.
Essential for Service – Replace when crown positions are vague, unstable, or fail to engage.
Compatible Movement – Designed for Omega Caliber 9300, 9301, 9303 (9300 series automatic chronograph).
