Replacement Oscillating Weight Rotor Compatible with Seiko Calibre 5J22A Kinetic Quartz Movement

Restore the power-generating function of a compatible Kinetic watch with this replacement oscillating weight rotor, designed for the Seiko Calibre 5J22A Kinetic quartz movement.

The oscillating weight rotates with wrist movement and transfers this motion through the generating-wheel system, allowing the movement to produce electrical energy for its rechargeable power cell. It is ideal for replacing an oscillating weight that is worn, damaged, loose, or no longer operating correctly.

Correct gear engagement, lubrication, and secure installation are essential for reliable electricity generation. Professional fitting by an experienced watchmaker is strongly recommended.
