The Rolex GMT-Master II reference 16710BLRO3 represents one of the most celebrated chapters in a storied lineage that dates back to 1955, when Rolex introduced the original GMT-Master in collaboration with Pan American World Airways to serve the needs of transatlantic pilots who needed to track two time zones simultaneously. By the time the GMT-Master II arrived in 1983, Rolex had refined the movement to allow the hour hand to be set independently of the minute hand, giving travelers and professionals true dual-time-zone functionality. The 16710 series, produced from 1989 through 2007, represents the final generation of GMT-Master II references to carry the aluminum bezel insert — and the BLRO variant, with its blue-and-red 24-hour graduated bezel, is the configuration known as the 'Pepsi'.

The case of the 16710BLRO3 measures 40mm in diameter and is made of stainless steel. The Oyster case is quintessentially Rolex: a three-piece construction with a screwdown caseback and a screwdown winding crown that together deliver 100 meters (330 feet) of water resistance. The overall profile is compact by modern standards, sitting close to the wrist and wearing with the balanced proportions that made 40mm Rolex sports watches a benchmark for decades.

The black dial on this reference is executed in Rolex's signature applied-index style, with luminous hour markers and Mercedes hands that ensure legibility under any lighting condition. The additional 24-hour hand, tipped in red, reads a second time zone against the blue-and-red bezel. The aluminum insert sits in a bidirectional 120-click bezel and uses red for the daytime hours and blue for the night-time hours.

Power comes from the self-winding calibre 3185, a COSC-certified chronometer; watches from late 2007 use the calibre 3186. The movement winds via a Perpetual rotor, so daily wear keeps it perpetually charged. While the 16710 generation predates some of Rolex's most recent movement advances, its reliability record over decades of professional and enthusiast use is exceptional, and it remains eminently serviceable by any qualified watchmaker with access to current Rolex parts.

On the wrist, the GMT-Master II 16710BLRO3 commands immediate attention without being ostentatious. The three-link Oyster bracelet is comfortable for all-day wear and pairs naturally with the brushed-and-polished case surfaces. This is a watch that transitions effortlessly from a business meeting to a weekend adventure, and its 40mm diameter makes it one of the most universally wearable references in the Rolex catalog.
