After 11 years, the battery in my Eric Haze is getting weak. l'd rather not do the battery change myself. From the research l've done, there's a tiny spring. And if you lose it the alarm no longer sounds. Does anyone know of a good watch shop in the USA l can send it to that's reasonably priced? l also have a GLX-5600 G Lide that's a few years old and l'd like to send that one too.
