Rolex Sea-Dweller

Rolex Sea-Dweller 4000 Ref. 16600

The 2001 Rolex Sea-Dweller 4000, reference 16600, is an absolute classic among professional dive watches and is considered by collectors to be one of the brand's most refined neo-vintage references. Originally developed for deep-sea specialist divers at the French underwater pioneering company COMEX, the Sea-Dweller offers maximum tool-watch functionality without aesthetic compromise. This example from the K series (2001) features its original Super-LumiNova dial, the sought-after drilled lugs (Lug Holes), and a fresh Rolex service from August 2026, fully documented with no gaps.

• Classic 40 mm Oyster case in stainless steel: Crafted from high-strength 904L stainless steel with characteristically satin-finished surfaces and polished sides. A true highlight of this transitional era, the case still features the sought-after drilled lugs (Lug Holes) for quick strap changes.

• Patented helium escape valve at 9 o'clock: The Sea-Dweller's unmistakable functional feature. When ascending from a pressurized chamber, it allows compressed helium gas to escape automatically, protecting the crystal from damage.

• Unidirectional rotating dive bezel with black Aluminium insert: Knurled bezel with precise 60-minute graduations and a luminous pearl (Tritium/Super-LumiNova) at 12 o'clock for precise decompression monitoring.

• Deep black dial without a Date magnifier: Unlike the Submariner, the classic reference 16600 forgoes the characteristic Cyclops magnifier over the Date at 3 o'clock, resulting in a particularly symmetrical dial and extremely high pressure resistance. Fitted with original Super-LumiNova luminous material.

• Extra-thick, flat Sapphire Crystal: A solid, high-pressure-resistant Sapphire Crystal reliably protects the dial from the extreme stresses of the deep sea.

• COSC-certified Caliber 3135 chronometer movement: Powered by Rolex's legendary workhorse movement, with automatic winding, a free-sprung Breguet hairspring, and Kif shock protection. Renowned for decades of accuracy and exceptional durability.

• Screw-down Triplock winding crown: Equipped with three independent sealing zones for maximum protection against water and dirt ingress.

• Extremely high water resistance (1220m / 4000 ft): Delivers uncompromising professionalism far beyond the limits of conventional dive watches.

• Solid Oyster steel bracelet Ref. 93160A: Fitted with a solid Oyster link bracelet, Fliplock safety folding clasp, and fold-out Fliplock diver's extension for wearing over a wetsuit.

• Official Rolex service (as of 08/2026): Freshly serviced in August 2026, ensuring perfect mechanical performance, verified water resistance, and flawless functionality, backed by an active international Rolex service guarantee.

• Neo-vintage icon in top condition: Reference 16600 combines the classic proportions of the five-digit Rolex era with modern everyday practicality and a complete service history.
