I've got a 1959 Omega Seamaster mechanical. I was winding it absent-mindedly the other day and think I may have gone the wrong direction for a few seconds. The crown became lose and started to unscrew. I was able to wind the watch and it's running fine, however, when I pull out the crown to set the time, I am unable to advance the hands. It can be moved backwards, but I believe that this is not good for the watch. Any suggestions before I take it to my local repair shop?
