The pilot's Rolex, complete from the Pan Am commission to the end of the aluminum era and into ceramic: eleven references across a family that forks in the middle - the original GMT-Master line ending with the 16700 in 1999, the GMT-Master II line that branches off at the Fat Lady and carries on, and the brown-bezel two-tone Root Beer branch that ran beside them both from 1970 to 2006. Two lines and a third color, one file.
