Rolex Submariner Date 40 mm 116619B1 White Gold Blue

The Rolex Submariner Date reference 116619LB—colloquially known as the "Smurf"—stands as one of the most recognizable and desirable watches in the entire Rolex catalog. Introduced as part of Rolex's expansion of the Submariner family into precious metals, this 40mm iteration pairs an 18k white gold Oyster case with a vivid blue dial and a matching blue ceramic Cerachrom bezel insert, creating a cohesive, all-blue aesthetic that is instantly identifiable on the wrist and in any room.

The Submariner lineage dates to 1953, when Rolex introduced what would become the defining template for the modern dive watch. Decades of refinement produced the 116619LB generation, which brought the corrosion-resistant and virtually scratch-proof ceramic bezel to the white gold Submariner for the first time, replacing the earlier aluminum insert. The blue Cerachrom bezel retains its color permanently—UV light and salt water cannot fade it—making this a dive tool that ages as gracefully as it performs.

At 40mm in diameter with Rolex's signature Oyster case architecture, the 116619LB offers a wrist presence that feels authoritative without being oversized. The proportions are classic Submariner: the Mercedes hands, the luminous Chromalight hour markers, the unidirectional rotating bezel graduated for elapsed dive time, and the Cyclops lens magnifying the date aperture at 3 o'clock all sit in perfect visual harmony. The polished and brushed finishing contrasts across the white gold case facets catch the light in a way no stainless-steel Submariner can replicate.

Powering the watch is Rolex's in-house automatic movement, a proven and rigorously tested caliber that drives the seconds hand in Rolex's characteristic smooth motion and is chronometer-certified by the COSC. The movement is protected by a screw-down Triplock crown and a screw-down Oyster caseback, together delivering the 300-meter (1,000 ft) water resistance rating that makes the Submariner Date a genuine professional instrument as well as a luxury object.

The Oyster bracelet in 18k white gold is secured by Rolex's Oysterlock safety clasp with Easylink comfort extension, allowing the wearer to adjust the bracelet length by approximately 5mm on the fly—an invaluable feature when transitioning between a wetsuit and bare wrist. On the secondary market the 116619LB consistently holds its value and frequently appreciates, driven by the combination of precious metal construction, strong collector demand, and the enduring cultural cachet of the Submariner name.
