The 136668LB marks a historic first: Rolex’s debut of a full yellow-gold Deepsea. Wrapping the Ringlock case architecture in 18ct gold transforms the tool-diver into a statement of uncompromising luxury — a 44mm instrument that pairs saturation-dive engineering with the visual weight and warmth of precious metal. The green “DEEPSEA” text on the dial mirrors the D-Blue convention while the all-gold execution stands alone in the current catalog.

The 136668LB Up Close: Case, Dial and Bracelet
Yellow gold covers the 44mm Ringlock case, crown, crown guards and bracelet links, producing a warm metallic glow that contrasts dramatically with the black dial and ceramic bezel insert. Despite the precious-metal exterior, the Ringlock architecture — nitrogen-alloyed inner ring plus domed sapphire — maintains the case’s structural integrity for serious depth ratings.
The black dial features gold-toned Chromalight indices and matching Mercedes-style hands that coordinate with the case metal. A date window under a Cyclops lens and the green “DEEPSEA” text complete the dial layout.
A gold Oyster bracelet with Glidelock provides 20mm of tool-free adjustment. Explore the full depth-rated lineup in the Deepsea collection.
