Replace the Battery of Anne Klein watch

It is an old watch for woman. My wife received it as a gift from her cousin about twenty years ago.

I found it from the old stuff in  Shanghai. It does not work because of battery.

When I home, I open it by the special tool, which I will mentioned later. Took the battery out and located the size or model number is 364.

Now it is simple, go to and bought a pack of this battery.


It is 5 PC pack. Brand name is Maxell, Silver Oxide Battery for Watch. 1.55V. Model number is 364 SR621SW SR60 363.

I made the order on Aug. 13, 2015. Received the item Today, Aug. 21, 2015. The back of the pack shows the exp. date 12.2016.

Have two Watch battery on eBay

I have a Roots sport watch, RY2202. The battery is exhausted.

I browsed retail stores in the town. I feel it is so expensive for the SR626SW battery locally.

So, I go to online and search it on eBay.

Later I found one here. $1.99 for two battery, plus $0.99 postage.


I made the order on May 27. And received it today.  See the picture below. I installed one battery into my Watch. So there is one empty box.


This is the one I got. I will keep one battery for backup.

The battery specification:

  • Maxell SR626SW
  • 377
  • 0% Mercury
  • Silver Oxide Cell
