.Pre-Owned Rolex Sea-Dweller – Ref. 126603 (2021)

43mm • Rolesor • Full Set
Stock Code: OT910T
Store Location: GA Jewellers, 8 Brighton Place

The Rolex Sea-Dweller 126603 is the perfect fusion of professional dive-watch engineering and unmistakable Rolex luxury. Introduced as the first two-tone Sea-Dweller in the model’s history, this reference blends extreme performance with refined Rolesor aesthetics, creating one of the most versatile modern Rolex sports watches.

This 2021 example, presented in very good condition, features a crisp black dial with luminous round hour markers, delivering outstanding legibility in all environments. The bold 43mm Oyster case provides serious wrist presence, while the signature yellow “SEA-DWELLER” text adds a subtle yet iconic contrast that nods to the model’s professional heritage.

Crafted in Rolesor — combining Oystersteel with 18ct yellow gold — the case, bezel and Oyster bracelet strike a unique balance between robustness and luxury. The watch is equipped with Rolex’s Triplock screw-down crown and protected by a sapphire crystal, ensuring uncompromising durability.

At its core is the Rolex Calibre 3235, a latest-generation automatic movement featuring the Chronergy escapement, Parachrom hairspring and an impressive 70-hour power reserve. Built for saturation diving, the Sea-Dweller boasts a remarkable 1,220 metres (4,000 ft) water resistance, making it one of the most capable dive watches Rolex has ever produced.

Supplied as a full set with original box and papers, this Sea-Dweller offers exceptional presence, performance and everyday wearability.
