The real shame about that Rolex that you have posted is that it is a GMT Master II. It is a watch which has an additional GMT hand which, when coupled with the standard numbered bezel allows the time in two additional timezones to be read. By replacing the numbers on the bezel with diamonds, the functionality of the watch is completely ruined.
The BLNR GMT II is a beautiful watch. I bought one last year and for travelling it is a joy to use. Being able to adjust the hour hand when you arrive at a different time zone while the second hand keeps moving is very satisfying. Will post a photo of it soon.
The Rolex GMT is another watch with a great history being, as it was, designed and made by Rolex at the request of Pan Am in the 1950s. They wanted a watch for their pilots who were travelling ever increasing distances in the glamorous new jet age of air travel which could tell time in multiple time zones. Fascinated as I am with air travel and in particular the golden era of the early jet age that is what lead me to ultimately buy my Rolex GMT, not because it was a Rolex but because of its history.
