9015 Modified Moonphase Movement

Miyota 9015 Modified Movement – Calendar & Moonphase Precision

We offer a practical upgrade to the reliable Miyota 9015 automatic movement, modified in our factory to include a calendar and moonphase function.
The movement keeps the original 9015 strengths: 28,800 vph for smooth seconds, 42-hour power reserve, hacking seconds, manual winding, and bidirectional automatic winding that charges efficiently through normal wear. We add:

Moonphase display at 6 o’clock — tracks lunar cycles clearly with a simple gold moon against a dark background
Grand calendar layout — shows weekday, date, and month in an easy-to-read format
Four-hand configuration — hours, minutes, seconds, and a dedicated date hand for quick reference

The large circular design fits comfortably in mid-size cases and looks balanced through an exhibition caseback, where the rotor and finishing show clean, professional work.
This movement suits brands or individuals who want a dependable automatic base with useful calendar and lunar features — accurate, serviceable, and ready for daily use.

The modified Miyota 9015 gives you solid performance and room for personal touches — no unnecessary complexity, just good watchmaking at a fair price.
