Setting the GMT Hand:
The 24 hour GMT hand sets independently. Unscrew crown and pull to position I, turning forward/clockwise will adjust the GMT hand by one hour increments. Turning the crown backwards/counter-clockwise will adjust the date. This is very convenient because you can adjust the GMT hand without hacking (stopping) the movement. For GMTs that require hacking the movement to adjust the GMT hand, it also requires readjusting the time.
