Rolex Submariner Date 40mm Blue Bezel “Serti Dial” Steel and Yellow Gold 16613SG CHAMPAGNE DIAMOND OYSTER

The Rolex Submariner reference 16613SG is constructed from 904L stainless steel and 18k yellow gold, a combination Rolex designates as “Rolesor.” The case and Oyster bracelet feature a combination of polished and brushed finishes, with the bracelet’s center links polished in yellow gold and the outer links brushed in steel. The 40mm case is topped with a unidirectional rotating bezel in blue anodized aluminum, framing a champagne-colored dial. This specific “Serti” dial configuration is set with diamond hour markers at the 6 and 9 o’clock positions, with applied gold markers at the remaining positions, all filled with Chromalight luminescence. This model represents a classic interpretation of the Submariner, blending the tool-watch heritage of the line with more traditional luxury materials.

At the core of this timepiece is the Rolex Caliber 3135, a self-winding mechanical movement known for its reliability. It features a Parachrom hairspring, which provides greater resistance to shocks and temperature variations. The movement is officially certified as a Swiss Chronometer. The primary complication is the date function, displayed at 3 o’clock under a Cyclops magnification lens. The watch maintains the Submariner’s traditional 300-meter water resistance, achieved through a screw-down Triplock winding crown and a solid case back. The functionality is enduring, focused on time and date with the robust performance expected from the Submariner lineage.

This particular example is in mint condition, showing only the most minor signs of any previous handling. It is accompanied by its original papers, which confirm its authenticity and provenance. The reference 16613SG with the blue bezel and Serti dial occupies a distinct position within the Submariner’s heritage-rich catalog. It is a less common variant compared to the standard black or blue dial models, which enhances its collectibility. As a two-tone model from a production period that has since been updated, it represents a specific era in the brand’s history. Its value is supported by the enduring demand for classic Rolex sports models, the appeal of the precious metal and diamond configuration, and its documented, well-preserved state.
