Reference Profile
This variant of the 116618LB retains the ceramic “maxi case” Submariner architecture and the classic blue-and-gold colour identity, but is distinguished by its factory diamond hour markers. While mechanically identical to the standard blue-dial model, the gem-set dial positions it firmly within Rolex’s luxury sports watch segment rather than the traditional tool-watch category.
Movement Overview
The watch is powered by the Rolex calibre 3135, an automatic movement that underpinned Rolex’s date-equipped professional models for decades. It offers approximately 48 hours of power reserve, includes a quickset date function, and is widely regarded for its robustness, accuracy, and long-term serviceability.
Functions & Complications
The 116618LB diamond-set displays hours, minutes, and central seconds, with a date aperture at 3 o’clock magnified by a Cyclops lens. It features a unidirectional 60-minute blue ceramic dive bezel, a screw-down Triplock crown, water resistance rated to 300 metres, and is fitted to a solid 18ct yellow gold Oyster bracelet with Rolex’s Glidelock extension system for fine, tool-free adjustment.
Buyer Considerations
This reference appeals to buyers seeking maximum visual impact and exclusivity within the Submariner lineup. Dial originality is critical, as aftermarket diamond dials materially affect value, while condition of the gold case and bracelet, polishing history, and completeness play a significant role in long-term desirability and pricing.
Comparisons & Aternatives
The diamond-set 116618LB is most often compared to the standard 116618LB, which offers a cleaner, more traditional Submariner appearance, and to other gem-set Submariners within Rolex’s catalogue. Outside the Submariner range, gem-set Daytona and GMT-Master II models provide alternative luxury sports watch options, though few combine full gold construction with true professional dive capability.
