: Hi All,

: Longtime lurker, first time poster. I have a quartz Heuer diver
: that I purchased on ebay several years ago. I wanted to give it
: to my sister for her birthday so she could at least be wearing a
: cool quartz watch instead of some BS. Sadly, the watch isn't
: working however. I took it to my watch guy and he said he
: couldn't fix it, but doesn't have much experience with quartz
: Heuers.

: I'm wondering if anyone could point me in the direction of someone
: who might be able to help? I'm in San Francisco, but I'd be
: willing to send it anywhere if there's a chance to get it
: working again. If not, it will probably end up back on ebay or
: on the sales forum soon, for parts or something!

: Here's a photo:
