New brothread Renata 377 SR626SW SR626 AG4 LR626 酸化銀水銀フリー電子バッテリー x 5

Bought these to replace a watch battery and they worked perfectly. Like Swiss-made product.

I purchased this item because I have a very large watch collection, this item is very reliable and the delivery is quick. I highly recommend this product.

Don't collect anything, cause that's all you will get as gifts from well meaning relatives and friends. I have MANY small clocks. Several were not working. All the batteries in the package work and time is no longer Noon/Midnight everywhere at the best price.

The only reason I gave it 4 stars is because the shelf life (expiration is within about 2 years) other than that it works great

Perfect fit!Great price!

Purchased from MYBATTERYSUPPLIER, they sent great fresh batteries made in Switzerland with a 9/2026 expiration date. Thank you

I change my own I used to pay $5 for a new watch battery change at watch shops. Now they want as much as $15-$25 for a single battery watch change. And you can't trust some newbie kid at a mall kiosk with your fine expensive watches.For $20, I bought a Kingsdun Watch Repair Kit on Amazon and I specifically bought these RENATA brand batteries which is a Swiss-made battery manufacturing company known for the most reliable and longest lasting watch batteries. A couple of youtube videos helped with more complicated tutorials.With 16 watches, I am saving a ton of money changing the batteries myself with these batteries.watch batteries now that watch shops are just too expensive.

Saved myself a lot of money changing my watch battery myself!
