The Rolex GMT-Master II Ref. 16700 “Pepsi” is the legendary final chapter of the classic aluminium-bezel GMT-Master lineage, a transitional and highly collectible timepiece that brilliantly fuses the original 1950s “Pepsi” aesthetic with the modern mechanical evolution of the late 1980s . Produced from 1988 until 1999, this 40mm stainless steel Oyster model features the iconic red and blue 24-hour graduated bezel insert which gives the watch its nickname, paired with a sleek black gloss dial and distinct white gold hour markers that replaced the earlier tritium versions, offering a crisp, enduring legibility . Its bidirectional bezel allows for effortless tracking of a third time zone, while the sapphire crystal with Cyclops lens provides a modern, scratch-resistant upgrade from its acrylic predecessor . At its heart beats the robust in-house automatic Caliber 3175, a COSC-certified chronometer that introduced the independent jumping hour hand—a fundamental feature for modern GMT functionality—while delivering a reliable 48-hour power reserve and a 28,800 beats per hour frequency . As the final reference to offer a “Pepsi” bezel with a steel case, the 16700 is a pure neo-vintage icon that embodies the spirit of jet-set travel and has become a cornerstone of serious collections, offering the perfect synthesis of Rolex’s pioneering past and its journey toward the contemporary era . Key specifications: 40mm stainless steel Oyster case; black gloss dial with white gold hour markers; Caliber 3175 automatic movement; 48-hour power reserve; red and blue “Pepsi” aluminum bidirectional 24-hour bezel; Oyster bracelet; 100m water resistance; sapphire crystal.
