Comments:
These Seiko 3027-29Y 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 / SOLAR MOVEMENT capacitor / battery for use in Seiko Kinetic and Solar watches.

Consisting of a Panasonic MT 616 with special connector plates, this Seiko part 3027-29Y is a replacement capacitor for the following Seiko watch movement calibres:

Seiko V18 series,
Seiko Solar V18 series,
Seiko 5K25,
Seiko V182A,
Seiko Pulsar Solar V182-0C00,
and
other Seiko calibres beginning with V18,

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

V182 - SEIKO TIME CORP, SEVEN JEWELL, JAPAN

inscribed on the back. The calibre, V182, is highlighted.

These 3027-29Y MT616 with tag are almost exclusively used in Seiko Kenetic and Solar electronic watches.

The Panasonic MT616 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.
