Rolex GMT-Master II 40 mm 16710C1 Steel Black

The Rolex GMT-Master II is one of the most recognized and storied sports watches in horological history, originally developed in partnership with Pan American World Airways to allow pilots and crew to track two time zones simultaneously. Reference 16710 — and the variant catalogued here as 16710C1 — represents a celebrated generation of the GMT-Master II produced in Rolex's Oyster Perpetual tradition, housing the dual-time-zone functionality in a 40mm stainless steel Oyster case that became the definitive size for this model family. Its legacy among aviators, adventurers, and serious collectors is second to none, making it one of the most sought-after pre-owned Rolex references on the secondary market today.

The design of this reference centers on a crisp black dial paired with a black aluminum bezel insert, a combination often referred to simply as the "black bezel" GMT and prized for its clean, utilitarian aesthetic. The aluminum bezel insert carries the signature 24-hour graduated scale that allows the wearer to read a second time zone at a glance by tracking the dedicated GMT hand against the bezel markings. The dial itself is finished in Rolex's characteristic style — sharp applied hour markers and luminous hands provide legibility in all lighting conditions, while the overall layout maintains the restrained, purposeful look that defines the GMT-Master II lineage.

Powering the watch is an automatic movement, true to Rolex's Oyster Perpetual engineering philosophy of self-winding reliability. The case construction offers 100 meters (330 feet) of water resistance, underpinning the watch's credentials as a genuine tool watch capable of handling the demands of daily life, travel, and light water exposure. The Oyster case and screw-down crown form the backbone of this water-resistant architecture, hallmarks of Rolex's commitment to robust, lasting performance.

The 40mm Oyster steel case sits on the wrist with a presence that is authoritative yet wearable across a wide range of contexts — equally at home with a suit, business casual attire, or weekend wear. The Oyster bracelet in stainless steel provides both comfort and security, with the folding Oysterlock safety clasp ensuring the watch stays firmly in place during active use. This reference wears as well today as it did when first produced, a testament to the timeless proportion and finishing that Rolex consistently achieved with the GMT-Master II generation.
