Rolex GMT-Master II 40 mm 16713K2 Steel/Yellow Gold Black Rolex GMT-Master II 40 mm 16713K2 Steel/Yellow…

The Rolex GMT-Master II is one of the most storied professional timepieces ever produced, originally developed in partnership with Pan American World Airways to meet the demands of long-haul aviation crews who needed to track two time zones at once. The reference 16713K2 belongs to the celebrated two-tone Rolesor family, blending stainless steel with 18-karat yellow gold in a combination that has made GMT-Master II references in this configuration among the most sought-after on the secondary market. This is a watch with genuine heritage, designed for a purpose, refined over decades, and now available in certified pre-owned condition through Bizak and Co.

The 40mm case diameter is the classic sizing for this generation of the GMT-Master II, sitting perfectly on a wide range of wrist sizes without the bulk of later sport models. The stainless steel and yellow gold construction — often called Rolesor — is executed on the Oyster case, which is renowned for its monobloc middle case, screw-down crown, and robust water resistance rated to 100 meters (330 feet). Every curve and surface transition on the case reflects Rolex's exacting manufacturing standards, ensuring both durability and visual refinement.

The black dial of reference 16713K2 is a commanding canvas, providing excellent legibility against the warm gold hour markers and hands that contrast with its depth. The aluminum two-tone bezel — a hallmark of this era of GMT-Master production — surrounds the dial and carries the 24-hour scale necessary for reading a second time zone at a glance. The interplay of the black dial, the Rolesor case, and the color-coded bezel insert gives this reference an unmistakable, confident aesthetic that remains as relevant today as when the model was first introduced.

Power comes from an automatic movement, as is the Rolex hallmark for the GMT-Master II family in this reference generation. The Oyster bracelet in matching steel and yellow gold completes the package, linking effortlessly at the wrist and lending the watch its signature versatility. The Oyster bracelet's solid-link construction and Rolex's precision clasp mechanism mean the watch wears securely and comfortably across long days of travel or wear.
