Anybody had this issue?

Has anybody ever had an issue where a movement's rotor is catching on the O ring, stopping it rotating all the way around and winding when on the wrist? I realised this was the issue because it could be wound by hand, but it wasn't self winding when on the wrist.

While I have not opened a lot of watches, I have seen enough to say I have never seen an O ring that thick. Is it also serving as movement holder? My very first observation is that is the wrong size ring for the watch, but should be an easy fix.

Thanks for your comment. I agree it does look thick, but after researching it, it does seem that the Vostok Amphibia (which is ehat this watch is) does have a rather chunky O ring - so I don't think that's the issue. It might have just warped slightly...

Ah, I was not sure which watch it was, but figured it was a Russian watch. Couple choices I suppose; Find a slightly smaller ring, or exacto that one. Could be a pain to source a full replacement, especially for what you paid. I would exacto it.

There are two possible causes:

  1.  The O-Ring is not cut properly or has warped over time.  Vostok doesnt have the best reputation for quality control, so it could be either of these, but it's more likely the latter one if it worked when you initially got it.  The Vostok caseback system reduces shear on the O-rings, but increases the pressure, so it may have been squeezed too hard at some point and deformed.
  2. The second possible issue is of greater concern.  The hole for the rotor bearing may have worn down over time, which is causing an excessive amount of wobble/play in the rotor, which should spin freely and in a flat plane.  You'd likely need a watchmaker to fix that, but with Vostok, it'd probably be cheaper to just source a replacement movement.
