Case, Ringlock System and Ceramic Dive Bezel 44mm Oystersteel Build
The Rolex Deepsea Sea-Dweller 116660-0001 super clone carries a 44mm Oyster case measuring 17.5mm thick, built on a 904L stainless steel core for accurate weight and corrosion resistance. The Ringlock case system layers a nitrogen-alloyed steel compression ring, a domed sapphire crystal, and a titanium-style caseback, the architecture that lets the genuine Deepsea resist pressure to 3,900 meters. The screw-down Triplock crown at 3 o'clock seals the case, and the helium escape valve at 9 o'clock releases trapped gas during saturation diving decompression.
Unidirectional Black Cerachrom Ceramic Bezel
The unidirectional rotating bezel carries a 60-minute graduated black Cerachrom ceramic insert with a luminous pearl at zero. The ceramic insert resists scratches and ultraviolet fade, holding its black color and engraved numerals over years of wear. The unidirectional action locks elapsed dive time so the reading only shortens if the bezel turns, which gives this super clone the safety behavior that defines a professional dive bezel.
Domed Sapphire Crystal and Compression Caseback
Scratch-resistant domed sapphire crystal with anti-reflective coating covers the black dial and forms a structural part of the Ringlock system rather than a simple cover. The thick domed profile lets the crystal withstand the water pressure rated to 3,900 meters. The screw-down caseback seals the Caliber 3135 clone movement against the steel compression ring, supporting the depth rating and water resistance of the 116660-0001.
