The 136668LB marks a historic first: Rolex’s debut of a full yellow-gold Deepsea. Wrapping the Ringlock-style case in yellow gold plating turns the tool watch into a statement piece, 44mm across and warm in colour from bezel to clasp. 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 plating 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. Under the yellow gold plating the case is 904L steel, like every watch in the shop.
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.
Movement Options: Swiss vs Japanese
Two caliber options are available for this gold Deepsea:
- Swiss Automatic — 28,800 vph with approximately 70-hour power reserve. Paramagnetic hairspring and Chronergy escapement follow Caliber 3235 engineering for efficiency and precision.
- Japanese Automatic (Miyota) — 21,600 vph with around 42-hour reserve. Practical daily option with accessible servicing and reliable timekeeping performance.
Both include quickset date and hacking seconds functionality.
