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
Seiko 5K22, 5K22A
Seiko 5K23, 5K23A
Seiko 5K25, 5K25A
Seiko 5K2J, 5K2JA
Seiko V14** (all calibres beginning with "V14"),
such as V142 and V142A, V145 and V145A, V14J and V14JA
The calibre is typically inscribed on the back of your watch. For example a watch might have........
inscribed on the back. The calibre, 5K22, is highlighted.
These 3023-24Y MT920 with tag are almost exclusively used in Seiko Solar electronic watches.
The Panasonic MT920 is a button-type titanium carbon lithium rechargeable Li-ion battery that uses lithium titanium oxide as the positive material, carbon as the negative material, and organic electrolyte.
