Why the GMT MASTER, and why the 16700? Because it was my first serious watch, THE watch which made me jump into the watch madness. In fact, when I was 16, I fell on a TV Series, called Magnum, in French. I saw Thomas Magnum as child saluting his father's coffin, wearing his father's Rolex 1675. I immediately fell in love with this watch and made the promise to myself that I will get one, one day.
