Reference 16710 represents the GMT-Master in a form that collectors recognize immediately: the red and black bezel split — nicknamed "Coke" — set against a black dial within a round 40mm stainless steel case. A scratch-resistant sapphire crystal sits above the dial, while a solid case back and screw-in crown complement the 100m/330ft water resistance. The self-winding movement delivers a 50-hour power reserve.
The stainless steel Oyster bracelet secures via a Rolex Folding Oysterlock Safety Clasp with Easylink 5mm comfort extension link, offering both security and a degree of wearability adjustment. The bidirectional 24-hour graduated bezel works alongside the dedicated GMT hand to allow simultaneous reading of two time zones at a glance.
This particular bezel combination occupies a distinct place among GMT-Master variations — less encountered than some alternatives, and predating the later ceramic bezel generations. It comes complete with box and papers, presented in very good condition.
