Rolex GMT Master II 40 mm 116710BLNR2 Steel Black

The Rolex GMT-Master II 116710BLNR2 — widely nicknamed the "Batman" by enthusiasts — is one of the most coveted references in the modern Rolex sport-watch lineup. It belongs to the GMT-Master II family, a line with roots stretching back to 1954 when Rolex developed the original GMT-Master in partnership with Pan American Airways to give pilots a reliable way to track two time zones simultaneously. The GMT-Master II, introduced in 1983, refined the concept with an independently adjustable 24-hour hand, making it the definitive professional dual-timezone tool watch.

The reference 116710BLNR2 is distinguished above all by its bidirectional rotatable Cerachrom bezel featuring a two-tone black-and-blue ceramic insert. Ceramic Cerachrom bezels are virtually scratchproof, colorfast against UV radiation, and retain their legibility far longer than earlier aluminum inserts. The black-and-blue coloring is achieved through Rolex's proprietary ceramic technology, and the contrast between the two halves — blue for day hours, black for night — is both functional and visually captivating. This is the detail that earned the watch its "Batman" nickname and made the 116710BLNR2 a defining reference of its era.

The 40mm Oystersteel case is the ideal size for a professional sport watch — substantial enough to command presence on the wrist yet wearable under a suit cuff without strain. The Oyster case architecture, with its screw-down crown and caseback, provides 100 meters (330 feet) of water resistance, making this GMT-Master II genuinely capable as an everyday companion whether you are in a boardroom or near the water. The black dial keeps the watch legible and classically Rolex, with luminous hour markers and hands ensuring low-light readability.

The watch is fitted on Rolex's Oyster bracelet, one of the most refined and durable three-link metal bracelets in watchmaking, known for its comfort, security, and longevity. The combination of a polished and brushed finish on the Oystersteel bracelet echoes the finishing on the case and creates a cohesive, purposeful aesthetic. The automatic movement within drives the GMT-Master II's complication reliably and without need for manual winding under normal daily wear.

This specific example is offered as a certified authentic pre-owned Rolex GMT-Master II, making it an exceptional opportunity to acquire a highly desirable reference at a price point typically below new-old-stock or new retail equivalents. The 116710BLNR2 was succeeded in Rolex's lineup but remains deeply sought after on the secondary market, with collectors valuing it for the distinctive Batman bezel colorway that its successors replaced.
