Review: Not sure why but each of the many watches we have seems to need a different battery size. These fit the bill for one of them. The price for all 5 was better then 1 in our local store. They arrived quickly, work (well, one for did for sure) and I have spares. I was impressed that they were made in Japan as well so I know that adults produced them.
