Rolex GMT-Master II Oystersteel — Black Dial, Grey & Black Cerachrom Bezel | Ref. 126710GRNR

Reference 126710GRNR, introduced in 2023, marked a pivotal moment for the GMT-Master II line: the first time Rolex paired the 40 mm Oystersteel Oyster case with a bidirectional rotatable bezel insert in grey and black Cerachrom ceramic — a colourway that rapidly earned the nickname 'Sprite' among enthusiasts. The combination of cool anthracite grey and deep black on the 24-hour graduated bezel is both technically striking and visually coherent against the gloss black dial, giving the watch a more restrained, tool-focused personality than the vivid two-tone predecessors in the range.

The movement is Calibre 3285, one of Rolex's most sophisticated in-house manufacture movements. It features the Chronergy escapement, a GMT hand independently settable in one-hour increments to track a second time zone, a 70-hour power reserve, and the Rolex Parachrom hairspring rendered in a proprietary paramagnetic alloy. The Oystersteel case is water-resistant to 100 metres and fitted with the Oysterlock safety clasp, providing a secure wrist experience. This 2024-production example is offered with box and papers, a significant provenance asset.

The 126710GRNR has already proven itself as one of the most sought-after modern GMT variants. Its Oystersteel construction democratises the reference relative to the two-tone and precious-metal variants, while the unusual grey-black bezel insert remains genuinely distinctive. Collectors who missed early allocations will find a near-new, fully documented example here — a watch that combines travel utility, horological depth, and strong market liquidity.
