When placing an Oris watch with the 400 caliber movement on a watch winder, which direction should it be wound in and how many turns per day?

For Oris watches equipped with the Calibre 400, 401, or 403 movement (with a 120-hour power reserve), the recommended watch winder settings are:

Direction: Counter-clockwise

Turns per day: 2,400

Winding duration: 10 hours (provides approximately 50 additional hours of power reserve)

Resting phase: 14 hours

These settings ensure optimal winding efficiency and help maintain the accuracy and longevity of your Oris watch.
