Rolex Submariner 40 mm 16613BLUF2 Steel/Yellow Gold Blue

The Rolex Submariner is arguably the most iconic dive watch ever made, and the two-tone reference 16613BLUF2 — affectionately nicknamed the "Bluesy" by watch enthusiasts — represents one of its most coveted expressions. Introduced as part of the 16613 family, this reference pairs stainless steel with 18k yellow gold on the case and Oyster bracelet, producing a luxurious yet athletic aesthetic that has captivated collectors for decades. Its blue dial and matching blue aluminum bezel insert create a harmonious monochromatic palette that is at once sporty and elegant.

At 40mm, the case diameter of the Submariner 16613BLUF2 sits at the classic, time-honored size that defined the Submariner lineage before the move to 41mm with the generation that followed. The Oyster case is constructed from a combination of stainless steel and 18k yellow gold, with the crown guards protecting the winding crown and giving the watch its unmistakable silhouette. The unidirectional rotating bezel, fitted with a blue aluminum insert marked with a sixty-minute graduated scale, is a functional dive tool that also serves as a striking visual anchor for the blue dial beneath.

The blue dial of the 16613BLUF2 is a study in purposeful design. Large luminous hour markers and Mercedes hands ensure legibility in low-light and underwater conditions, while the cyclops lens over the date window magnifies the date 2.5 times for easy reading at a glance. The overall effect is rich, deep, and deeply satisfying — a dial that rewards close inspection and commands attention on the wrist.

Power comes from Rolex's automatic movement, a self-winding caliber with a proven track record of reliability and precision that has served the Submariner across many generations. The movement winds via the motion of the wearer's wrist and is housed securely within the screw-down Oyster case, contributing to the watch's impressive 300-meter (1,000-foot) water resistance. This engineering integrity means the 16613BLUF2 is as capable in the water as it is at the boardroom table.

The Oyster bracelet in steel and yellow gold echoes the two-tone theme of the case and lends the watch a presence that is both robust and refined. The integrated design flows seamlessly from lug to clasp, sitting comfortably on a wide range of wrist sizes. Few watches transition as effortlessly from a diving expedition to a formal dinner, which is precisely why the two-tone Submariner has remained a perennial bestseller on the secondary market.
