For a Rolex GMT-Master II, set your watch winder to 650 Turns Per Day (TPD) using bidirectional (both clockwise and counter-clockwise) rotation. This setting ensures the automatic movement stays accurately wound by mimicking the natural motion of the wrist, which applies power to the mainspring in both directions.
Why these settings are important:
Bidirectional Winding: The rotor in a Rolex GMT-Master II, like most modern automatic watches, spins in both directions to wind the mainspring. Using bidirectional winding on your winder ensures it powers the movement regardless of which direction it rotates.
650 TPD: This number of rotations per day is sufficient to keep most Rolex watches, including the GMT-Master II, fully wound when worn or on a winder.
No Overwinding: Modern Rolex watches have a clutch mechanism that prevents over-winding. You can't damage your watch by putting too many rotations on it in a day.
How to get started:
Check Your Winder: Ensure your winder has settings for both TPD and winding direction (clockwise, counter-clockwise, or both).
Set the TPD: Select 650 TPD on your winder.
Set the Direction: Choose the bidirectional or "both" setting for the winding direction.
Place the Watch: Place your Rolex GMT-Master II in the winder and close the cover. The winder will then begin to automatically rotate your watch.
