A new battery should be an easy thing to get?
I have one watch that I wear regularly. I did have a plastic sports watch that I wore hiking but one of the seals on it failed and the last time I went hiking in the rain some water got inside it. I'm still trying to figure out how I might get the moisture out to see if I can get it going again. I really liked that watch. I've got a couple of other watches I picked up over the years that need minor things done. I've got a Citizen that I bought back in 1995 that needs a spring bar in the strap, a Rotary I picked up remarkably cheaply that really needs a new strap, and an assortment of other watches I picked up in job lots that need combinations of adjustments and batteries. At some point I need to get around to putting fresh batteries in a load of them and posting pictures online to sell them. And then there are the watches in a bad state of disrepair that aren't useful as anything other than being parts donors. I had two watches that were more or less identical - one worked but the body was pretty bashed up and the other had a nice body but didn't work, so I swapped out the parts so I had one that looked nice and worked, and one that was bashed up and didn't work.
