In this video, I remove and reinstall the Miyota 8210 automatic movement from a Citizen Tsuyosa.
This is part of my ongoing watchmaking journey, documenting each step carefully while learning how modern automatic movements are secured and handled inside the case.
The Miyota 8210 is a reliable and widely used automatic caliber, making it an excellent movement to study for case handling and movement alignment.
