I recently bought a 1921 Hamilton 992 lever set watch, my first keyless. Setting works fine, but winding only works with the pendant pointing down, toward the ground. If the pendant is upright the crown and stem just spin freely together, i.e. like when rotating CCW, unless I turn the watch upside down first and keep some CW pressure on the crown as I return it to upright. Something seems to be falling down when upright, so I wonder if there is a spring that isn't working properly to maintain engagement. Suggestions? Thanks!
