Rolex, Deepsea, 136668LB, Blue Dial, Yellow Gold, Oyster Bracelet, 44mm

The Rolex Deepsea 136668LB-0001 is a 44mm professional dive watch that combines extreme underwater capability with full 18k yellow gold construction.

The case is built using the Ringlock system, a reinforced architecture designed to withstand substantial pressure at significant depths.

Its unidirectional rotatable bezel features a blue Cerachrom ceramic insert with engraved and gold-coated graduations for precise dive timing.

The blue dial offers strong contrast with the yellow gold case.

Large hour markers and hands are filled with Chromalight, providing long-lasting blue luminescence in dark environments.

Powering the watch is the Rolex Calibre 3235, a self-winding movement delivering approximately 70 hours of power reserve and reliable chronometric performance.

The Triplock screw-down crown and helium escape valve contribute to a water resistance rating of 3,900 metres.

A domed, scratch-resistant sapphire crystal protects the dial, while the solid caseback supports structural integrity under pressure.

The watch is fitted with an Oyster bracelet in 18k yellow gold, secured by an Oysterlock clasp and equipped with the Glidelock and Fliplock extension systems for precise adjustment.

With its precious metal construction and professional dive specifications, the Deepsea 136668LB-0001 presents advanced underwater engineering in a distinctive and substantial configuration.
