I bought a 7002 on eBay a couple of months ago from a business seller in the UK who stated it had been "fully overhauled" & was "in near perfect condition".
It kept terrible time so I returned it for adjustment, but when I got it back it was no better, so I found out on this site how to calibrate it & did it myself. It now keeps pretty good time.
My problem now is that once a week or so, it just stops. This happens when it is on my wrist & I assume it's fully wound as I've been wearing it daily for weeks now. If I shake my wrist it starts again but will probably stop again in a few days.
I don't have a good relationship with the guy I bought it from so can't see him being very effective in sorting it, so can anyone advise what the problem might be? I appreciate it may be a difficult question to answer, but do you have any experience of a similar fault with this type of watch?
Thanks very much
