Reference Profile
This variant of the 16618 belongs to the late–five-digit Submariner Date generation and is distinguished by its blue aluminium bezel, blue dial, and “T<25” tritium dial marking. It features classic 40mm proportions, drilled lugs, and slimmer case architecture compared to later ceramic models, and is often viewed as emblematic of 1990s Rolex design in precious metal form.
Movement Overview
The watch is powered by the Rolex calibre 3135, an automatic movement that formed the backbone of Rolex’s date-equipped professional watches for decades. It provides approximately 48 hours of power reserve, includes a quickset date function, and is renowned for its durability, accuracy, and long-term serviceability.
Functions & Complications
The 16618 displays hours, minutes, and central seconds, with a date aperture at 3 o’clock magnified by a Cyclops lens. It features a unidirectional aluminium 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 a folding clasp.
Buyer Considerations
This reference appeals particularly to collectors who value tritium dials and the warm patina that develops over time on the luminous markers and hands. Colour consistency between dial, bezel insert, and patina is an important factor in desirability, while gold wear, polishing history, and originality of components play a significant role in determining market value.
Comparisons & Aternatives
The blue tritium 16618 is often compared to its black-dial counterpart, which offers a more understated appearance, and to later blue gold Submariners such as the 116618LB, which feature ceramic bezels and heavier modern cases. Within the same era, the two-tone 16613LB provides a less precious-metal-intensive alternative with similar colour identity and period styling.
