Rolex GMT-Master II 40 mm 16713 holes s-3 Steel/Yellow Gold Black Rolex GMT-Master II 40 mm 16713 holes…

The Rolex GMT-Master II reference 16713 is one of the most celebrated two-timezone watches ever made, sitting at the intersection of professional tool-watch heritage and luxury aesthetics. Originally developed in close collaboration with international airlines to give pilots and crew an instant read on two time zones simultaneously, the GMT-Master II evolved over decades into a cult collector's piece that remains instantly recognizable on the wrist of travelers, executives, and watch enthusiasts around the globe. Reference 16713 represents the Rolesor chapter of this story — a pairing of corrosion-resistant Oystersteel with warm 18k yellow gold — and it continues to command serious attention on the secondary market.

At 40mm, the case diameter of the 16713 sits in what many consider the sweet spot for a sport-dress watch: substantial enough to read clearly across a conference table yet trim enough to disappear under a dress-shirt cuff when the occasion demands. The Oyster case construction — Rolex's signature hermetically sealed architecture with a screw-down crown and solid case back — gives the watch the robust character expected of a professional instrument, while the yellow gold crown, bezel ring, and bracelet center links elevate it well beyond utilitarian territory.

The black dial is a study in legibility. Applied hour markers and the Rolex Cyclops date magnifier (positioned at 3 o'clock) provide instant orientation in any lighting condition, while the distinctive GMT hand — traditionally in a contrasting color — sweeps through all 24 hours in a single rotation, allowing the wearer to read a reference city's time against the 24-hour graduated aluminum bezel insert. The aluminum bezel itself is a hallmark of the classic GMT-Master II era, carrying that period-correct aesthetic that collectors specifically seek out in references like the 16713.

Inside the case, an automatic movement drives the watch with the dependable self-winding architecture that Rolex has refined over generations, requiring nothing more than the motion of the wrist to stay wound during regular wear. The Oyster bracelet — rendered here in matching Rolesor with brushed steel outer links and polished yellow gold center links — completes the package with the security and comfort that the three-piece link design has delivered for decades. The fold-over Oysterclasp keeps the bracelet securely fastened and allows for easy on-wrist adjustment.
