I bought the watch depicted below just under a year ago. In the Vostok Europe blurb they say that the watch will keep time to within 30 seconds a day and that it has a reserve of 31 hours! When I actually checked the watch it kept going for over 50 hours, but it was gaining 45 seconds a day! I regulated the watch to the best of my ability and it now keeps time to within less than +2 seconds a day in any position, on or off my wrist!! No kidding! Why couldn't they have spent a few minutes on an electronic timer and played around with the regulating lever, instead of not bothering and claiming only pathetic timekeeping in their advertising? I understand that this movement can be made to keep excellent time as I have discovered myself.

Cheers,
Martin
