If ever you are unable to find your watch model in this table, here's an easy way to determine the winding requirements for your IWC watches.

  • Select the combined winding mode (CW+CCW) and the minimal number of turns per day (TPD).
  • 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 increment.
