Genco Timepieces “Elegance in Every Second”
The Rolex Sea-Dweller 43mm Red Letter (Ref. 126600) represents a perfect balance between Rolex’s legendary deep-sea heritage and modern innovation. First introduced in 2017 to celebrate the 50th anniversary of the Sea-Dweller, this model reintroduced a beloved detail from the original vintage references—the striking red “Sea-Dweller” text—earning it the nickname “Red Letter Sea-Dweller.”
A Legacy Reborn
The Sea-Dweller has been Rolex’s ultimate tool watch for professional divers since its debut in 1967. With the Ref. 126600, Rolex pays tribute to its past while offering cutting-edge upgrades for today’s collectors and adventurers. The bold red lettering on the dial harks back to the historic Ref. 1665, while the enlarged 43mm Oystersteel case enhances wrist presence and wearability compared to its predecessors.
For the first time in Sea-Dweller history, this reference also features the iconic Cyclops lens over the date window, improving legibility without compromising the model’s robust character.
Superior Engineering
Crafted from Rolex’s corrosion-resistant Oystersteel, the watch features a unidirectional black Cerachrom ceramic bezel with engraved numerals and graduations, built to withstand the toughest conditions. The case integrates a helium escape valve, ensuring professional-grade functionality for saturation divers.
Water-resistant to an impressive 1,220 meters (4,000 feet), the Sea-Dweller continues to be one of the most capable dive watches ever made.
Movement Excellence
At its core, the Ref. 126600 is powered by the Rolex Caliber 3235, a self-winding mechanical movement certified as a Superlative Chronometer. This advanced movement incorporates the Chronergy escapement for improved efficiency, delivering exceptional precision and reliability. It offers a 70-hour power reserve, making it as practical on land as it is beneath the waves.
