Comments:
These Seiko 3027-29N 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 616 with special connector tabs, this Seiko part 3027-29N is a replacement capacitor for the following Seiko watch movement calibres:

Seiko 3M21, 
Seiko 3M22, 
Seiko 3M62, 
Seiko 3M21A, 
Seiko 3M22A, 
Seiko 3M62A, 

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

 3M22 - SEIKO TIME CORP, SEVEN JEWELL, JAPAN

inscribed on the back. The calibre, 3M22, is highlighted.

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

You may wish to look at the excellent web page "Replacing the Capacitor on a Seiko 3M22" by Daniel N. Ravenna. This page shows the Seiko Kinetic (Caliber 3M22).

This 3027-29N MT616 with tag is the newer enhanced performance longer duration type. If you are replacing the original version based on a SL621 cell you will need to replace your clamp. Do not order this battery (which comes without a clamp). Instead click here to order our 3027-3MZ which contains a rechargeable battery unit and a rechargeable battery clamp. See here or use the 'Contact Us' link in the left hand frame for more details.

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.
