Rolex Sea-Dweller

Manufacturer/Model: Rolex Sea-Dweller 4000 Reference: 16600 Year: 2001 Condition: Top condition This particular example from the K series (2001) features the original Super-LumiNova dial, the sought-after drilled lugs (Lug Holes), and the seamlessly documented, fresh Rolex quality service from August 2026. Classic 40mm Oyster case made of stainless steel: Crafted from high-strength 904L stainless steel with characteristically satin-finished surfaces and polished sides. Patented helium escape valve at 9 o'clock: The unmistakable functional feature of the Sea-Dweller. It allows for the automatic release of compressed helium gas when surfacing from the pressure chamber and protects the glass from damage. Unidirectional rotating diver's bezel with black aluminum inlay: Bezel with precise 60-minute graduation and luminous pearl (Tritium/Super-LumiNova) at 12 o'clock for exact decompression control. Deep black dial without date magnifier: Unlike the Submariner, the classic reference 16600 forgoes the typical cyclops lens over the date at 3 o'clock, resulting in a particularly symmetrical dial appearance and extremely high pressure resistance. Filled with original Super-LumiNova luminous material. Extra-thick, flat sapphire crystal: A massive, pressure-resistant sapphire crystal reliably protects the dial from extreme deep-sea stress. Chronometer manufacture caliber 3135 (COSC certified): Powered by Rolex's legendary workhorse with automatic winding mechanism, free-sprung Breguet balance, and Kif shock protection. Known for decades of accuracy and indestructible robustness. Screw-down Triplock crown: Equipped with three independent sealing zones for maximum protection against the ingress of water and dirt. Extremely high water resistance (1220m / 4000 ft): Offers uncompromising professionalism far beyond the limits of conventional dive watches. Massive Oyster steel bracelet Ref. 93160A: Equipped with the massive Oyster link bracelet, Fliplock safety clasp, and the extendable Fliplock dive extension for adjustment over the wetsuit. Official Rolex service (as of 08/2026): Recently serviced in August 2026 – guarantees perfect mechanical performance, tested water resistance, and flawless functionality with existing international Rolex service warranty.
