Rolex GMT Revisisted

My friend Henry has asked me to help him find a nice Pepsi vintage Rolex GMT.

From the record, one can see the following variations in GMTs:

1. 6542 : No Crown guard (Cal 1030 or 1035, 1065 movements)
   
2. 1675 : Cal 1565 movement (1959-64) & Cal 1575 movement (1965 - 1980)
3. 16750 : Cal 3075 Arcylic (1981-88)
4. 16760 : Cal 3081 (1983-88)
5. 16700 : Cal 3175 (1988-1999)
6. 16710 : Cal 3186 (1989-2007)
7. 116710: Green Arrow, Ceramic bezel

From the net, we can see variation in term of case, movement and even arrow (Small arrow, big arrow and even ALL red arrow)
