Cr425 battery

I was looking for a replacement watch battery, when my attention was drawn to a cell (not for my watch!) I had never seen before: the cr425. It has to be the smallest cell I have ever seen…just need to find a use for one or two….miniature key chain light?

Edit:

I might have known that you folks would already have a thread on the subject! world's tiniest
