The new Rolex Deepsea ref. 136668LB marks a significant milestone as the first precious-metal version of Rolex's 44 mm professional dive watch. Crafted from 18K yellow gold, this model features a striking glossy royal blue dial and a blue Cerachrom bezel. The case measures 44 mm in diameter, 17.7 mm in thickness, and 51.8 mm lug-to-lug, with a 22 mm spacing between the lugs. It is water-resistant to an impressive 3,990 meters (12,800 feet), featuring a 5.5 mm thick sapphire crystal and an automatic helium escape valve.
The RLX Titanium screw-in case back contrasts sharply with the yellow gold case, adding a unique touch. The watch is equipped with an 18K yellow gold Oyster bracelet with the Glidelock clasp, providing both elegance and functionality.
Powered by the Rolex Calibre 3235 movement, it offers a 70-hour power reserve, operates at a frequency of 28,800vph, and is chronometer-certified for precision.
Functions include hours, minutes, seconds, a quick-set date, and a unidirectional 60-minute bezel. With its luxurious materials and robust engineering, the Rolex Deepsea ref. 136668LB is a standout piece for those who can confidently wear a substantial watch in precious metal.
