Rolex Sea-Dweller 43 Steel/Yellow Gold 126603 - 2021

Rolex Sea-Dweller 43 Ref. 126603 (Steel/Yellow Gold, 2021)

The Rolex Sea-Dweller 43 with reference 126603 from 2021 is the most powerful and luxurious interpretation of Rolex’s legendary professional diving watch. Originally developed in 1967 for the extreme demands of deep-sea diving, the Sea-Dweller series made history in 2019 when Rolex integrated precious metal into this uncompromising tool watch for the first time. In the stunning bicolor version (Yellow Rolesor), the massive, functional presence of a deep-sea watch merges with the aristocratic elegance of 18-carat Yellow Gold. An impressive, highly functional statement on the wrist that combines unwavering engineering with luxurious appeal.

• Spectacular material mix (Yellow Rolesor): The case and outer links of the bracelet are made from extremely durable Oystersteel (904L Steel). The crown, bezel knurling, and center links of the bracelet are crafted from radiant 18-carat Yellow Gold. This contrast gives the robust professional watch a distinctive, noble dynamic.

• The expressive 43-mm Oyster case: With a diameter of 43 mm, this Sea-Dweller has an impressive visual dominance and perfect proportions for stronger wrists. The golden “Sea-Dweller” inscription on the deep black dial is a stylish nod to the two-tone bicolor concept.

• The patented helium valve: As a true reference for extreme divers, the case features an automatic helium escape valve at 9 o’clock. It allows helium that enters the watch during saturation diving in the pressure chamber to safely escape during decompression without damaging the Sapphire Crystal.

• Black Cerachrom ceramic bezel: The unidirectional rotating diving bezel is equipped with a scratch-resistant, UV-resistant insert made of black Cerachrom ceramic. The numerals and graduations are coated with a fine layer of pure Yellow Gold using a PVD process, ensuring perfect legibility and a noble shine.

• First time with Cyclops lens: The new generation of the Sea-Dweller introduced in 2017 equipped the model line for the first time in its history with the iconic Rolex Cyclops lens at 3 o’clock, which magnifies the Date on the scratch-resistant Sapphire Crystal by two and a half times.

• State-of-the-art manufacture caliber 3235: Inside works the latest generation mechanical movement with automatic winding. Equipped with the patented Chronergy escapement and the antimagnetic blue Parachrom hairspring, the caliber offers an impressive power reserve of approximately 70 hours as well as highest precision (-2/+2 seconds per day).

• Extreme diving depth and luminosity: Thanks to the Triplock winding crown and the hermetically screwed case back, the Sea-Dweller guarantees phenomenal water resistance of up to 1,220 meters (122 ATM / 4,000 feet). The Chromalight display with long-lasting blue glow ensures flawless legibility even in the darkest ocean depths.

• Oyster bracelet with Glidelock extension: The watch is worn on the three-row bicolor Oyster bracelet with Oysterlock safety folding clasp. The integrated Rolex Glidelock fine adjustment system allows the bracelet length to be adjusted in 2-mm increments up to 20 mm without tools – ideal for wearing the watch comfortably over a diving suit.

• An impressive collector’s piece (vintage 2021): As a 2021 edition, the Ref. 126603 embodies the perfect symbiosis of the latest Rolex technology and a bold, luxurious design philosophy. A coveted, extremely value-stable eye-catcher for connoisseurs who want to combine maximum performance with unabashed luxury.
