>The rechargable battery for one of these is literally $10 on eBay, and I can't believe there wasn't anyone around you willing to fit it. I can believe larger chains refusing it, but come on, a small jeweler or watch repair shop would have done it I'm sure.
I went to a Macy's watch repair department, a well-known jewelry store, and two small watch repair shops (the "old man in a tiny office in an office building" type) highly ranked on Yelp. All refused.
