Why Miyota Movements
Why the Mineral collection runs the Miyota 8215, and what that means for owners.
The Mineral collection (natural-stone dials) runs the Miyota 8215 - the Japanese automatic workhorse from Citizen's movement division.
Miyota 8215
- Automatic, 21 jewels, 21,600 vph, ~42 h power reserve
- In production since 1977 - one of the most proven automatic calibres ever
- Parts and service available at any watchmaker, worldwide
Why a Japanese movement in a Swiss-assembled watch?
Honesty first: Mineral references are therefore not Swiss Made and are not labelled as such - see the designation table. The 8215 was chosen for the Mineral line because it delivers reliable mechanical timekeeping at a price that keeps a genuine natural-stone dial affordable. Where the catalog is Swiss Made (Corvin, Regent, Arden, Davos), it says so; where it is not, it says so too.
