Comments:
These Seiko 3027-26Y 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 516 or MT516F with special connector plates, this Seiko part 3027-26Y is a replacement capacitor for the following Seiko watch movement calibres:

Seiko 1M20.

IF YOU DON'T SEE THIS NUMBER 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........

1M20 - SEIKO TIME CORP, SEVEN JEWELL, JAPAN

inscribed on the back. The calibre, 1M20, is highlighted.

These 3027-26Y MT516 with tag are almost exclusively used in Seiko Kenetic electronic watches.

The Panasonic MT516 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.
