Rolex GMT-Master II White Gold — Green Ceramic Bezel "Sprite" | Ref. 126729VTNR

The GMT-Master II in 18-carat white gold with the green and black Cerachrom bezel insert — colloquially dubbed the "Sprite" — occupies a singular position in Rolex's professional catalogue as both an instrument of precision dual-timezone timekeeping and one of the most coveted collector's pieces of the modern era. The 40 mm Oyster case, machined from solid 18-carat white gold, exudes a cool, luminous quality that amplifies the vivid chromatic contrast of the bidirectional 24-hour graduated bezel.

That bezel insert is crafted from Rolex's proprietary Cerachrom ceramic — a virtually scratch-proof, fade-resistant compound whose rich forest-green and midnight-black sectors are rendered with chemical vapour-deposited platinum numerals and graduations. The dial's green ceramic panels echo the bezel, creating a composed aesthetic that reads as both purposeful and sculptural. Chromalight luminous plots and a luminescent GMT hand ensure excellent legibility across multiple time zones at a glance, day or night.

Powering the 126729VTNR is Calibre 3285, Rolex's pinnacle GMT movement. Its Chronergy escapement — a nickel-phosphorus lever and escape wheel architecture — reduces energy losses while a paramagnetic Parachrom hairspring resists magnetic disruption. The result is 70 hours of power reserve, COSC-certified chronometer accuracy, and a rapid-setting independent GMT hand that advances in one-hour increments without disturbing the local time display. The 18-carat white gold Oyster bracelet with Oysterlock clasp and 5 mm Easylink extension completes an exceptional instrument for the well-travelled collector.
