... like the Cal. 822 powered Reverso Classique - a beautiful watch by the way, congrats! -
you have to use a considerable amount of force! When the spring is fully wound it will
give resistance to further winding, which you should normally notice while winding.
Also - as I understand it - overwinding will leed to the spring breaking, so that there
will no further power be delivererd through the gear train. The watch will not run at all
with a broken spring.
So what you experience looks like another problem to me. Try to wind the watch fully - until
you feel the resitance - and monitor how it runs. If the problem persists take the watch to
your dealer.
Good luck!
