Review on LI-CB 40-Pack Watch Battery Replacement Set - 371 SR920SW 370 AG6, High-Capacity Silver Oxide 1.55V Batteries For Long-Lasting & Leak-Proof Performance In Watches by Julie Youngbear

I bought these batteries to replace one battery in my watch. The cost of 10 batteries for less than $6 was far cheaper than bringing the watch to a jeweler for a replacement battery. I happen to have the tool set to properly remove and replace the watch's backing. Sometimes it's easy to do with out this tool. If you can replace your own battery this is a great deal. The battery works great in my watch. I will update if it fails to perform.
