Raketa Calendar Watch
The watch did not wind at first
so I opened it up and the problem was rather simple. The big winding wheel's screw was loose. The wheel turned above the crown wheel. Tightening that screw was all it took to make it work again. Sometimes the problems are really not grave. However when I tried to open the chromium plated 3133 Poljot Chronograph that day, I wasted 2 hours, a lot of nerves and sweat and had to give up. The stainless steel case back was just sitting too tight and my whole collection of case openers failed... I will bring it to some real professional soon because I want to complete the Russian movement shots.
