 The first question is easily answered, but without a very very fine force measuring device I can't tell you. It's on the scale of a hundredth of a Newton though I'm willing to bet.

You would know better than I, but with the very efficient gear trains in most modern watches, the force multiplier from the stem to the mainspring probably negates any change you might "feel" as feedback. Thats why most winding watches have some sort of clutch system - which may be as simple as a plate with a specific friction coefficient that will not grip the mainspring barrel once it reaches a certain preset.
