pepsi gmt

[mamamia1]

my ad for rolex is telling me that the pepsi gmt is sure to become a collectors peice.do the serial numbers on these watches show that is was an original pepsi gmt.i know that there are alot of these watches out there.but if rolex can not color the ceramic bezel,and demand gets high then supply and demand takes place.i feel that this watch will go up in value if rolex stops coloring the bezel.i was going to trade my blue sub in for it.give me some advice.another member insists that this watch will not become a collectors peice because the paperwork does not show blue and red bezel,so you can buy a bezel and swap it.i understand that but on a authentic rolex would know that it was produced as an original.
