Rodman’s still has a place on the downstairs level that does this. Give them a call. They were a lot less expensive than Tourneau and Chas Scwartz and Son, but I don’t know what they charge now.

I change most of our watches myself. My husband's one, I couldn't get the back of the watch back on. Didn't there used to be kiosks in malls that did this kind of thing?

This is simple DIY via YouTube.

Open up the back of your watch, note the kind of battery and replace yourself. Watch batteries can be purchased are available everywhere.

$100 ans $700 watches so nothing very fancy. I am not handy but don’t have much disposable income.
