Notes: This is the first and only two-tone execution of the Sea-Dweller, combining the extreme functionality of the professional diver with the luxury of Yellow Rolesor (Oystersteel and 18K Yellow Gold). The "Sea-Dweller" text on the dial is printed in gold, a unique feature for this reference.

Condition Assessment

Overall Condition: Pre-Owned - Excellent. This timepiece is in honest, original condition with signs of light and careful wear on the polished surfaces. The case remains full and sharp, and while a light professional polish would bring it to a showroom finish, it currently retains its factory dimensions.

Dial, Hands, & Crystal: The intense black dial is flawless. The yellow gold hands and Chromalight luminous markers are pristine. The sapphire crystal and Cyclops lens over the date are free of any blemishes.

Case & Bezel: The 43mm Oystersteel case is in excellent shape, maintaining its crisp lines. The 18K yellow gold unidirectional bezel and black Cerachrom insert are perfect with no notable scratches or chips.

Strap/Bracelet & Clasp: The Yellow Rolesor Oyster bracelet is tight and exhibits only minor surface hairlines on the gold center links consistent with light wear. The folding Oysterlock clasp features the professional-grade Glidelock extension system and Fliplock extension link, both operating perfectly.

What Makes the 126603 Special

The Rolex Sea-Dweller 126603 is a truly surprising and highly important reference, marking the first time the historically all-steel, ultra-tough Sea-Dweller line was offered in Yellow Rolesor (two-tone steel and yellow gold). Launched in 2019, this model takes the rugged capability of the Sea-Dweller—with its 43mm case, Helium Escape Valve, and immense 1,220m water resistance—and elevates it to a level of luxury previously reserved for the Submariner.

This fusion of extreme function and precious metal makes the 126603 a highly distinctive choice. Unlike the all-steel 126600, this reference features the "Sea-Dweller" text on the dial printed in gold, further distinguishing it from its tool-watch sibling. Housing the state-of-the-art Calibre 3235, which offers a 70-hour power reserve and the Chronergy escapement, this watch provides the ultimate combination of technical robustness and everyday luxury, appealing to collectors who demand both performance and opulence.
