FAQ

1. Is this automatic wheel an original CITIZEN/MIYOTA genuine part?
Yes. It is an original MIYOTA factory part, made in Japan. The 9015 is a newly designed movement from 2009 within the 9000-series premium thin caliber range. Purchase through authorized channels to ensure authenticity.

2. Which movements is this automatic wheel compatible with?
It fits the MIYOTA 9015 automatic caliber. The 9015 measures just 3.90mm thick with a beat rate of 28,800 bph (4Hz) and approximately 42 hours of power reserve. The 9015’s automatic winding system is unidirectional (winds in one rotor direction, free-spins in the other).

3. What happens if the automatic wheel is damaged?
The automatic wheel is central to the self-winding mechanism. Damage can cause the rotor to spin freely without winding, disabling the automatic winding function. The automatic wheel and related components are subject to wear over time—timely replacement is recommended. Symptoms may include abnormal rotor movement or noise.
