These Seiko 3023-44Z 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 Maxell TC 920 S with special connector plates, this Seiko part 3023-44Z is a replacement capacitor for the following Seiko watch movement calibres:

Seiko 5M62
Seiko 5M63
Seiko 5M65

The calibre is typically inscribed on the back of your watch. For example a watch might have........

220905 - 5M62 - OACO

inscribed on the back. The calibre, 5M62, is highlighted.

These 3023-44Z TC920S with tag are almost exclusively used in Seiko Kenetic electronic watches.

The Maxell TC920S 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.
