The Rolex GMT Master 16713 history began in the early 1950s with the introduction of the first GMT Master pilot’s watch. The line was initially developed as a tool watch for the professional pilots of the Pan American Company, just as the airline had begun to offer transatlantic flights from New York to Paris. The GMT Master’s primary function was to provide a means for reading a second time zone. The ref. 16713 is an exceptional variation of the line that includes a stunning steel and gold finish, a brown dial topped with luminous hour markers and hands, and a unique two-tone bezel insert dubbed by collectors as the Root Beer. If you’re in the market for a unique collector’s item, the Root Beer Rolex 16713 is an excellent option to consider.
