I bought my this watch used because I liked the design. The name of the watch makes the date of manufacture obvious. The seller claimed the watch was serviced but from the day I received it stops intermittently. Sometimes I look at the watch on my wrist and it is stopped, other times it is significant time, but is running: I know the later is happening because the watch stops and start primarily from my physical movement. When I find it stopped a shake of the wrist will often get it going again. During tougher times i've had tp tap it with my finger several times to get it running again and with each tap the second hand will jump forward or backward a couple of seconds, which seems suspect to me.
As this watch is 24 years old could it just be too warn out to be serviced or is it likely I was lied to about it being serviced? I like the design enough to put some money into it. My research tells me it has a 2414a movement. Is it feasible to buy a new $32 Vostok and swap the movements? Thanks.
