I am relatively new to working on watches. the 12 o'clock marker became dislodged on my oris so I decided to take the watch apart to put it back in place which seemed pretty easy. I had no problem removing the crown and stem out of the watch and removing the movement and reinstalling the marker on the dial but now that I am putting everything back together I cannot get the stem reinserted correctly. The stem can be pushed all the way into place but when turned it does
nothing. so is there something I am not doing right? any help would be appreciated.
