These Seiko 3023-24R 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 3023-24R is a replacement capacitor for the following Seiko watch movement calibres:
Seiko V12* series (V121, V121A, V122, V122A),
Seiko 5Y75, 5Y75A,
IF YOU DON'T SEE ONE OF THESE NUMBERS ON YOUR WATCH THEN THIS IS THE WRONG BATTERY FOR YOU.
The calibre is typically inscribed on the back of your watch. For example a watch might have........
WATER RESIST - 7M22 - 8809-A4
inscribed on the back. The calibre, 7M22, is highlighted.
These 3023-24R MT920 with tag are almost exclusively used in Seiko Kenetic electronic watches.
You may wish to look at the Norwegian web page "Urreparasjon" The top section of the page shows the Seiko A. G. S. (Caliber 7M22).
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.
