Just bought an 8800 aqua terra and the crown is a little odd. When unscrewed, it doesn't pop out like almost every other watch I've owned. It kind of just goes Into the winding position if that makes sense. Typically On other watches when you push in to screw it back into the case it feels like you are pushing against a spring, this one does not at all. Very stiff to screw back in. Is this a different screw in crown design than others?
