Position 0
– Position 0is the crown fully screwed in, where it should always be when not setting the time to ensure the watch stays water resistant.
Position 1
– Position 1 is the position that the crown naturally pops into once unscrewed. This position allows for manual winding, but not the adjustment of any hands.
Position 2
– Position 2 is when the crown is pulled out to the first notch. This gives control over the main hour hand, which jumps forwards or backwards in one-hour increments. Additionally, the date window will change forwards or backward as the hour hand passes midnight; however, it is worth noting that Rolex GMT-Master II watches don’t have a Quickset date function, which would give the ability to change the day of the month in the three o’clock window by just turning the crown.
Position 3
– Position 3 is when the crown is pulled all the way out, and provides access to the traditional time-setting functions, where the seconds hand stops and both hour hands plus the minute hand can be adjusted either forwards or backwards by rotating the crown.
