377 SR626SW 1.55V 0% Hg Silver Oxide Watch Battery (5 Batteries) Made in Japan by Seiko

Exactly what was needed to replace watch battery. Great price and quality too.

good battery

First of all, we live in Arizona and this time of year it is very hot! Heat is known to destroy batteries. I always purchased Duracell's because I thought they were the best batteries. Recently I had to purchase several Button batteries for my collection of watches. Several orders arrived "dead on arrival"! Time after time I ordered 367/377 batteries and when they arrived, I tested them. All tested marginal right off the card. Usually barely 1.0V. I used a multimeter and battery tester on each battery. I thought maybe the watch was defective, but I noticed when I installed one the second hand would move slightly and then quit.I decided to give Seizailken 377's a try and they worked perfectly after installation. Needless to say, I am impressed!

I have a very small clock embedded into a crystal that was a wedding gift 30 plus years ago and I found it in a deep drawer with the battery dead. It was very hard to figure out what the battery size was so I had to use a magnifying glass. I got the original battery that was made in Japan. It is repackaged into a smaller package size, which works great for me because I didn't need 20 of these. I just needed one. It worked great out of the package and I'm happy to be enjoying my wedding gift all over again. I recommend it.

Works great.

Arrived today. Works fine in the watch as a replacement for dead battery.

looked high and low locally for the right size battery for my watch. I finally used a magnifying glass to read the correct name and size. Ordered it on Amazon at it fit perfectly!!

I tried other batteries, but none worked for replacing my watch batteries. These WORK! Highly recommend if you hope to replace your watch batteries and save the cost of going to a jeweler. Highly recommend!
