For more than half a century, Rolex fans associated Rolex GMT-Master watches with two bezel-color combinations, red/blue and red/black. These bezels are so well-known that they have nicknames: “Pepsi” and “Coke,” respectively, because they call to mind those brands’ trade dress. So when a new, unprecedented, black-and-blue version of the GMT-Master II showed up in Rolex’s window at Baselworld last year, buzz abounded.
