The Rolex Sea Dweller, developed for professional saturation divers in the 1960s, was the first to use the helium escape valve to depressurize divers without risking the watch. The model changed its character from a compact 40 mm tool to an advanced Deepsea with a Ringlock System. Continuous innovations made the Sea Dweller one of the pre-owned Rolex most competent and trusted professional timepieces, blending technical perfection with timeless design.
16600
The 16600 is endowed with a 40 mm case, an aluminium bezel and no Cyclops crystal which together provide a clean look with a purpose. It is still a widely sought after model among the collectors due to the fact that it is very reliable and has great proportions with no modern bulk, thus the classic Sea Dweller function is enjoyed by the collectors.
116660 (Deepsea)
The first Deepsea showcased the Ringlock System, the 44 mm case and incredible depth resistance. Its daring design, as well as its large size, attracts collectors who want the maximum technical possibility, and is one of Rolex's most sophisticated diving constructions.
126600
With a 43 mm case, red dial text, and Cyclops date, the 126600 fuses modern ease with old Sea Dweller roots. It has been widely regarded as the most contemporary version because of its perfect hight on the wrist without Deepsea thickness and excellent wrist presence.
126660 (Deepsea)
This new Deepsea model re shapes the proportions, adds comfort to the bracelet, and provides colour options such as the D Blue dial. It is a watch that is highly desired for its better ergonomics but still bears the deep performance that a true Deepsea must have.
16660 (Triple Six)
A transitional reference that showcases the sapphire crystal, depth rating increase, and upgraded caliber as its main features. Its ability to attract vintage and modern lovers at the same time has made it a historically important piece that serious collectors are always on the lookout for.
136660 (Deepsea)
The latest Deepsea model offers not just the best movement but also perfection in size and easier wearing. It will be loved by the ones who wish to have the latest technical breakthroughs along with the model's impressive size and authority.
The Sea Dweller range includes 40 mm, 43 mm and 44 mm models, each equipped with a helium escape valve, deep water capability and robust Oystersteel construction. Variants include aluminium or ceramic bezels, black or gradient dials and bracelet upgrades, offering collectors strong durability and unmistakable Rolex identity.
The Sea Dweller appeals to both men and women who appreciate high performance tool watches with technical authenticity. The 40 mm references offer balanced everyday wear, while the 43 mm variants provide modern comfort and presence. The 44 mm dweller suits those who prefer a bold, commanding aesthetic with advanced engineering. Across the UK, collectors of all styles value the Sea Dweller for its durability, heritage and long established position within the Rolex professional family.
