Patek Philippe

small piece

 

Hard to believe such a small piece has the strength to wind the watch. The winding stem kept coming out of my 3800. I read in the instructions that some movements come out from the front so the winding crown easily pulls out to allow this. To reinstall simply insert and turn until it re locks in place. My 3800 was one of those movements and I never could reinstall it myself. The 315 caliber is not one of those listed in the instructions as having the pull out feature. Clearly, the design intent is for the crown to break rather than the movement/mainspring with undue pressure in all the calibers. I have been told the correct motion to extend the winding crown is with a prying type action with a thumb nail and not a direct pull with the fingers.
