Best Price Square2 X Renata Watch Battery - Swiss Made - Silver Oxide Renata Batteries - Renata 377 (SR626SW)

As always these batteries do the job. I always use Renata in my premium watches as they have a longer life. There are others of the same quality but I prefer to match Swiss made with Swiss made. For my non Swiss brand watches I use the Chinese made batteries which are very good. But always Renata for the high end time pieces. Price wise very good also.

The Casio watch has four tiny screws to hold the back on.YT has countless videos on watch battery replacement.Because of the easy back removal, I found the correct model of battery from the Casio watch model number on the WWW.Amazon sold the best quality Swiss watch batteries at a very reasonable price.I should think that it look more than five minutes to open the back, change the battery and put the back on again.It was an easy and quick job ~ but you do need a tiny cross head screwdriver to remover the screws

This product is good. Highly recommend.

Quality Swiss made arrived on time

Incredible value compared with a visit to the Jewellers shop. Easy to fit.

There's not a lot I can say about batteries but these were a very good price and they arrived less than 24 hours after ordering.My daughter found some old watches and wanted to use them which is why I bought these batteries, and as soon as I put them, in the watches were working.They feel to be good quality and so far they've lasted well. Would definitely recommend.

Very good and reasonably priced

Good Quality and lasts a long time...these two will keep you going for years...
