Rolex GMT-Master II White Gold — Black Dial, Diamond & Black Sapphire Bezel | Ref. 116759SANR

The GMT-Master II Ref. 116759SANR occupies a singular position in the Rolex catalogue: a professional aviator's tool reconceived entirely in 18K white gold and adorned with one of the most exceptional gem-set bezels ever produced in Geneva. The 40 mm white gold Oyster case is set with 76 brilliant-cut diamonds across its entire surface, transforming the instrument watch silhouette into an object of extraordinary jewellery complexity. The bezel — set with 36 diamonds and 12 black sapphires in alternating arrangement — replaces the conventional Cerachrom insert with precious stones whose hard brilliance mirrors the technical function it performs.

Calibre 3186 drives this GMT-Master II with the precision demanded by intercontinental travellers. Its independently adjustable GMT hand — advanced or retarded in one-hour increments without stopping the seconds hand — allows rapid home-time setting during layovers. A Parachrom hairspring ensures resilience against magnetic fields and mechanical shock. The 24-hour disc beneath the bezel references the second time zone at a glance, distinguishing day from night in any global city, and COSC certification confirms chronometer-grade accuracy.

The black lacquer dial provides a dark, authoritative ground against which the white gold applied hour markers and luminescent hands deliver crisp legibility. The contrast between the gem-set bezel's colourless diamonds and deep black sapphires echoes the day/night function encoded into the 24-hour ring — an alignment of form and purpose that distinguishes great watch design. The 18K white gold Oyster bracelet with Fliplock extension clasp completes a reference that commands over $109,000 — the GMT-Master II as haute joaillerie without concession to its professional DNA. Water resistant to 100 metres.
