Comments:
These Seiko 3023-24Y devices were originally not batteries at all, but miniature capacitors. More recently however, Seiko has upgraded their specification and replaced them with minute rechargeable batteries.

This is a genuine SEIKO KINETIC MOVEMENT capacitor / battery for use in Seiko Kinetic watches.

Consisting of a Panasonic MT 920 with special connector plates, this Seiko part 3023-24Y is a replacement capacitor for the following Seiko watch movement calibres:

Seiko 5K21, 5K21A

These 3023-24Y MT920 with tag are almost exclusively used in Seiko Solar electronic watches.
