Rolex GMT-Master II Oystersteel & Everose Gold — Tiger Iron Dial, Grey/Black Cerachrom Bezel | Ref. 126715CHNR

Reference 126715CHNR occupies a singular position in the GMT-Master II family, pairing the workhorse Oystersteel case with a bracelet crafted entirely in Rolex's proprietary Everose gold — a two-tone combination the manufacture calls Rolesor. The grey and black Cerachrom bezel insert, introduced with this reference, earned the watch its colloquial "Sprite" nickname in certain markets, though it is the astonishing Tiger Iron dial that truly sets this piece apart. Mined from a metamorphic rock exhibiting natural bands of gold, red, and brown, each Tiger Iron dial is wholly unique, making every 126715CHNR a one-of-one object.

The movement powering this reference is the Calibre 3285, Rolex's flagship GMT calibre. Built entirely in-house at the Plan-les-Ouates manufacture, it incorporates the Chronergy escapement — a high-efficiency system offering 15 percent more energy efficiency than conventional Swiss lever designs — alongside a bidirectional self-winding Perpetual rotor and a 70-hour power reserve. The paramagnetic blue Parachrom hairspring resists shocks and temperature variations with exceptional reliability.

Presented in like-new, unworn condition, this 126715CHNR is a collector's opportunity of the first order. The combination of a semi-precious stone dial, Everose gold Jubilee bracelet, and current-generation movement makes this reference one of the most coveted and hardest to source in the entire Rolex sports-watch ecosystem. Its natural stone dial ensures that no two examples are identical, elevating it far beyond a mere timepiece into the realm of wearable objets d'art.
