Replacement Oscillating Weight Rotor Compatible with Seiko Calibre 7D46A Kinetic Quartz Movement

Restore the automatic power-generation system of a compatible movement with this replacement oscillating weight rotor, designed for the Seiko Calibre 7D46A Kinetic quartz movement.

The oscillating weight rotates in response to wrist movement and transfers energy through the oscillating-weight wheel to the generating system. This allows the movement to produce and store the electrical energy required for operation.

Ideal for replacing a worn, loose, damaged, or non-rotating rotor during movement servicing or restoration. Correct installation can help restore smooth rotor operation and reliable power generation when the remaining charging components are functioning properly.
