Sony 377 (SR626SW) 1.55V Silver Oxide 0% Hg Mercury Free Watch Battery (2 Batteries)

You can find this battery from several sources but you won't find a better value. Local big chain stores charge a lot more for one and most online sources force you to buy in packs of several. Here I was able to get two batteries at a fantastic price. Shipping took a couple of weeks but less time than was described in the details for the maximum time to receive. Since the price was so good for a quality name brand battery it was well worth the short wait. I will buy from this vendor again for my future battery needs.

RECENT purchase, not sure about longevity. Great price, easy installation and watch works great.Just prior to ordering from Amazon, recently had battery installed professionally, battery lasted about 9 days and quit. Took a chance with Amazon/DIY, watch is still working great and much more practical.

It lasted one month then died. That's what you get for cheep.

CoVid 2020 - the battery was pretty easy to replace, but putting the back of the watch back on was not. If your watch back is a pressure type, I suggest you put it on a towel, cover the back with something so it wont scratch and use a board if you don't have a machine. So far, it's working just fine. We're now in last November 2020

I bought a watch at Walmart years ago and the battery died so I thought I would look to see if I could replace the battery myself and Amazon had the cheapest prices. I received 2 batteries with this purchase, SO I have an extra when if quits working again in a year or so. It was a perfect fit and a Japanese brand to which I like.
