Rolex Submariner Date Yellow Gold — Black Dial | Ref. 116618

The Submariner Date in 18K yellow gold has occupied a singular position in Rolex's professional sports lineup since the introduction of the all-gold Sub in the 1980s — a watch that reconciles the Submariner's tool-watch DNA with the ostentation of solid precious metal. Reference 116618 is the 40mm predecessor to the current generation 126618, powered by Calibre 3135, water-resistant to 300 metres via the triple-locked Triplock crown. The 40mm Oyster case in 18K yellow gold is engineered to the same standards as its steel counterpart, with Oyster-grade screw-down crown and case back.

The black unidirectional rotating bezel insert is crafted from Cerachrom — Rolex's proprietary ceramic compound, virtually impervious to scratches and UV-induced colour fade — with the elapsed-time scale moulded directly into the material. The black lacquer dial carries luminescent Chromalight rectangular hour markers and Mercedes hands, both filled with long-duration blue lume for low-light legibility at professional diving depths. Calibre 3135 is a COSC-certified perpetual with approximately 48 hours of power reserve, a bidirectional winding rotor, and Rolex's proprietary Parachrom hairspring for anti-magnetic resilience.

The yellow gold Oyster bracelet with its Glidelock extension clasp allows diver-precise adjustment in 2mm increments, accommodating a wetsuit cuff without removing the bracelet. Reference 116618 in yellow gold with black dial is a cornerstone of any serious Rolex sports-watch collection — the gold Submariner at its most purposeful and collectible.
