Hi, After servicing a Wostok 2209 movement, which included cleaning, reassembly and regulating it, I was quite happy with the amplitude and general time keeping performance. I left the movement running for a couple of days to test the power reserve also, which was beyond 24h and probably within the 38h, as per spec. The issues started after I installed the dial and hands, and noticed the movement stopping suddenly after few minutes. I removed the hands and dial, the hour wheel, thinking it maybe due to increased friction somewhere in the hands, or the dial rubbing something, but the symptoms continued - balance would start very easily but stop after around 4 - 5 minutes. My only guess is that the balance bridge may have distorted when I installed the hands. I did lay the movement flat on the cushion and on a harder plastic surface to press the hands, and that may have affected the balance bridge. I have no other explanation, especially why it takes so long for the balance to stop. I don't see the balance touching anything really. It happens when dial up and dial down as well. I would appreciate any advise on the matter. -

I dont see how this one works for a call on each hour, ounting the hour -

It depends where you like and what they advice on getting rid of chemicals.
