Another nice feature is the strap. Made from Barenia leather, the black strap is specially fitted to the case in a satisfying way that always look good for watches like this. I have to say that over the last few years with the decrease in metal bracelets being released, most brands have really been raising the bar for strap to case integration quality.
There are two primary ways to make use of the GMT feature. First, with the bezel marker set to 12 o'clock, change the GMT to point to the current Greenwich Mean Time (GMT) which is the same as the timezone in London. Change the hour hands and set it to the current timezone. With the Rolex GMT-Master II this is done easily as the minutes move with the GMT hand when the crown (unscrewed) is pulled two positions and the hours hand moves by itself when the crown is in the first position.
The complicated rubber strap doesn't disappoint. It has a series of flaps so to say and does a good job of snugly securing to your wrist. It looks a bit bat ray-ish (well of course it does). It might have a ton of part and pieces, but it is rather comfortable given the pretty huge (wide and thick) watch on your wrist. I'd say that you need to wear it for yourself to really understand what it feels and looks like.
