Heritage Narrative Introduced in the late 1980s, the Rolex GMT-Master II reference 16713 represents a pivotal evolution in Rolex’s dual-time travel watch lineage. Building upon the legacy of the original GMT-Master developed for Pan Am pilots in the 1950s, this model introduced the independently adjustable hour hand, allowing the wearer to track a second time zone without disrupting the minute hand — a hallmark of modern Rolex engineering. This 1991 example showcases the classic Rolesor construction — a blend of stainless steel and 18k yellow gold — complemented by a black gloss dial with luminous hour markers. The black aluminum bezel insert with gold 24-hour scale adds both function and contrast, maintaining the unmistakable aesthetic that has made the GMT-Master II one of Rolex’s most enduring tool watches. Powered by the Calibre 3185, this model combines robust precision with smooth operation and a power reserve of approximately 50 hours. With its 40 mm Oyster case and signature two-tone bracelet, the 16713 is both a practical traveler’s instrument and a timeless expression of Rolex design.
