When you need a quality watch battery

It's Duracell, so I know it will probably outlast the watch it's being used in, it's the right battery for my watch, and it arrived in the mail quickly and at a good price. That checks all my boxes!

Works well!

My watch died and I sourced online for a replacement battery. At first, I was worried that it wasn't the right scale, but it fit perfectly. Per lifespan, I've only had it replaced for a couple weeks. Will see how it holds up. Shipping was fast!

This battery is very tiny could barely see it so be careful opening the package. Thanks to Walmart I couldn't find this anywhere else.
