well I had this in with a job lot of faulty watches and a couple day's ago.
I got round to having a look some one had over wound the hell out of it but some gentle encouragement got the balanced wheel spinning and over the next few hour on and off it start to run then stop so back to encouraging it to run well.
Each time it would get longer intervals in between it stopping .till it final stop so I tried to wide it and it work so half wound it and wore it for a day work great so last night I tried to fully winder it and great it work like a charm,and tonight it's still going and is about spot on so my only Wostok at the minute![]()
