If you could not find your watch model (or caliber) in this table, you may determine your JEAN MARCEL winding mode on a trial basis. You should select the combined winding mode (CW+CCW) and the minimal number of turns per day (TPD). Then place your watch into the winder and check after a few days how accurate your watch shows the time. If it runs behind, it is necessary to increase the number of TPD by one step.
