The Rolex GMT-Master "Pepsi" is among the most iconic and immediately recognizable nicknames in all of watch collecting, referring to the blue and red bezel insert — colors shared with the famous soft drink brand — that has distinguished certain GMT-Master references since the very beginning. The original Bakelite Pepsi bezel appeared on the ref. 6542 at the GMT-Master's 1954 debut, followed by the aluminum version on the ref. 1675, which became the dominant vintage Pepsi reference over its long production from 1959 to 1980. The aluminum Pepsi bezel continued through the ref. 16710 into the 2000s. In 2018, Rolex reintroduced the Pepsi colorway in ceramic with the steel ref. 126710BLRO — a release so anticipated that it generated years-long waiting lists and immediate secondary market premiums. White gold Pepsi references including the 116719BLRO had previously kept the colorway alive for precious metal buyers. Pre-owned GMT-Master Pepsi references span seven decades of production and multiple case generations, making this one of the deepest and most diverse collecting categories in the Rolex universe. DeMesy & Co. in Dallas has authenticated pre-owned Pepsi GMT-Master watches across all generations since 1987.
