This is a genuine MIYOTA operating lever for the 9015 movement, made in Japan, designed for the 9015 premium automatic caliber. It is a core component of the keyless works, converting the crown’s push/pull action into axial movement of the clutch wheel for switching between winding, time setting, and quick date setting modes.

1. Is this operating lever an original CITIZEN/MIYOTA genuine part?
Yes. It is an original MIYOTA factory part, made in Japan.
2. What happens if the operating lever is damaged or misaligned?
The operating lever is a critical component of the keyless works. Wear, deformation, or misalignment can cause crown operation failure, including: inability to set time after pulling the crown, stem not locking in place, or mode switching failure. When removing the crown, press the setting lever only about 0.5mm—excessive pressure may dislodge the operating lever or other parts. Timely replacement is recommended.
3. Does this part come with installation tools or instructions?
No. This is a single precision component. Installation involves disassembly of the keyless works and requires professional tools. Work should be performed by a qualified watchmaker.
