Hi. It takes a 377. I just put new batteries in every watch that takes one before I posted them. :). Thanks for watching my auctions I noticed your on a few of them Good luck to you if your bidding. :)
I have more watches but some take less common batteries so until I get batteries that work on them I won't post them. I want to be sure I can tell people weather they will work or not. Some I know need fixed but they are real old so when I do post them I will let people know they need fixed. :)
