These Seiko 3023-24X 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 3023-24X is a replacement capacitor for the following Seiko watch movement calibres:

Seiko 5J21, 
Seiko 5J22, 
Seiko 5J32, 
Seiko 5S21, 
Seiko 5S22, 
Seiko 7D46,

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

inscribed on the back. The calibre, 7D46, is highlighted.

These 3023-24X MT920 with tag are almost exclusively used in Pulsar Kenetic and Seiko Kenetic 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.
