And that is exactly what the Vostok instruction manual advises, too.I've got a bunch of vostoks myself, nice watches, I've even got one with the same dial as yours around here somewhere. There is a quicker way to set the date on those. Move the time forward to 24:00 so the date clicks forward, then move the time back to 21:00. You should see the date start to move back then click as you go back past 21:00. Then keep going forward and back between 21:00 and 24:00 until you have the right date.
