I just received my Explorer II from TT its the ROLEXP2003B and I am a little confused on the movement. I have done searches but I cant find any answers to my questions, the date changes with the hour hand at the 6 o'clock pos. and also I was reading that the GMT had could be used as a different time zone but it seems that the hand moves half speed as the hour hand?? Could someone please shed some light on this for me?? Thanks for the help!
