Reference Profile
This variant of the 116619LB retains the ceramic-bezel Submariner “maxi case” and monochromatic blue colour scheme, but is distinguished by its factory diamond hour markers. While visually similar to the standard “Smurf” at a distance, the gem-set dial positions it firmly within Rolex’s high-luxury sports watch offerings, reflecting the brand’s approach to blending tool-watch design with jewellery elements.
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 116619LB 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 white gold Oyster bracelet with Rolex’s Glidelock extension system for fine, tool-free adjustment.
Buyer Considerations
This reference appeals to buyers seeking a Submariner with maximum exclusivity and visual impact while retaining professional specifications. Dial originality is critical, as aftermarket diamond dials significantly affect value, while white gold wear, polishing history, and full-set completeness play a major role in long-term desirability and pricing.
Comparisons & Aternatives
The diamond-set 116619LB is often compared to the standard “Smurf,” which offers a cleaner, more utilitarian aesthetic, and to later gem-set Submariners with redesigned cases and updated movements. Within Rolex’s wider catalogue, gem-set Daytona and GMT-Master II models provide alternative luxury sports watch options, though none combine white gold construction and dive-watch heritage in the same way.
