Rolex Submariner Cookie Monster 126619LB Black Dial on Oyster

The 126619LB sits at an interesting intersection in Submariner history: a white gold Submariner with a blue ceramic bezel and black dial, a combination that collectors immediately dubbed the "Cookie Monster" for the contrast between the blue bezel and black dial — blue and black, like the Muppet's coloring. Rolex introduced the 41mm case with the generation-5 Submariner in 2020, enlarging the case from the long-running 40mm format and housing the movement in a more substantial Oyster case with thicker lugs. The caliber beneath is the Cal. 3235, Rolex's current-generation manufacture movement featuring a Chronergy escapement — a nickel-phosphorus lever and escape wheel that reduces energy loss by roughly 15 percent compared to the prior lever geometry — and a 70-hour power reserve, a meaningful step up from the Cal. 3135 it replaced.

White gold is the correct metal for this reference. The yellow gold 126618LB reads warmer and softer; white gold sharpens the contrast between the blue ceramic bezel and the black dial, giving the watch a colder, more architectural presence on the wrist. The black dial with dot indices is the factory configuration — no sunburst, no texture, just a flat matte surface that absorbs light rather than reflecting it, which is precisely what makes the luminous plots read so cleanly at depth. This example is offered in excellent condition, with very good condition noted uniformly across the case, bracelet, bezel, dial, and crystal.

Offered in excellent condition as a full set, with Rolex original box and warranty card.
