I will leave the chronograph module as it is for the moment, and start servicing the movement only. If the watch performs well with that, we can save us servicing the chronograph module
this is the culprit - the intremediate ratchet wheel is broken
the barrel bridge is damaged as well
the chronograph module is too hard to move, and will need a service, too
the chronograph module brakes down the movement almost to a halt - the Dubois Depraz module needs servicing as well
the clean chronograph module parts
pushers taken apart and cleaned
super performance - even with the chronograph engaged
