Rolex Submariner 40 mm 16613SERTIS1 Steel/Yellow Gold Silver Rolex Submariner 40 mm 16613SERTIS1 Steel/Yellow Gold…

The Rolex Submariner is one of the most recognizable and enduring watch designs in horological history, having defined the archetype of the modern dive watch since its introduction in the 1950s. The reference 16613SERTIS1 represents a cherished chapter in that lineage — a two-tone Submariner Date built on a 40mm Oyster case combining 904L stainless steel with 18k yellow gold, a pairing Rolex calls Rolesor. This combination brings a warmth and richness to the Submariner's purposeful silhouette that has made two-tone references perennial favorites among collectors and everyday wearers alike.

The 40mm case diameter is the classic Submariner footprint, a size that defined the model for decades and continues to sit ideally on a wide range of wrist sizes. The case is fitted with the Submariner's signature screw-down Triplock crown and Oysterlock-secured Oyster bracelet in matching steel and yellow gold, ensuring both security and comfort. Water resistance is rated to 300 meters (1,000 feet), underscoring the Submariner's credentials as a genuine professional dive instrument.

At the dial, the silver face provides a clean, high-contrast canvas against the warm gold hour markers and hands. The aluminum bezel insert, graduated to 60 minutes, frames the dial in the Submariner's characteristic rotatable diver's timing configuration. The overall aesthetic strikes a balance between technical seriousness and luxury warmth that few watches at any price point can replicate.

Powering the 16613SERTIS1 is a Rolex-manufactured automatic movement, reflecting the brand's commitment to in-house production and precision timekeeping. Rolex automatic movements of this era are renowned for their robustness and long service intervals, making them well-suited to daily wear across decades. Routine servicing by a qualified watchmaker ensures this reference will continue to perform reliably for years to come.

On the wrist, the two-tone Submariner occupies that rare sweet spot between sport watch and dress watch — equally at home in boardroom or on the boat deck. The 40mm Rolesor case catches light in a way that the all-steel reference cannot, while remaining far more understated than a fully gold model. It is a watch that rewards the wearer who wants versatility without sacrificing character.
