Rolex Sea-Dweller 126603
The Rolex Sea-Dweller 126603 is a bold fusion of strength and elegance, combining Rolex’s legendary deep-sea capability with luxurious two-tone styling. Crafted in a blend of Oystersteel and 18k yellow gold, this 43mm diver’s watch makes a striking impression while offering uncompromising performance.
Equipped with the automatic Caliber 3235, this model delivers exceptional accuracy, a robust 70-hour power reserve, and a quickset date function. The black dial is perfectly matched with a unidirectional Cerachrom bezel in black ceramic, offering both legibility and durability. A scratch-resistant sapphire crystal protects the face, while the iconic Oyster bracelet ensures a secure, comfortable fit under any condition.
