Replica Rolex Sea-Dweller Deepsea Black Dial 44mm 116660

The 116660 Deepsea was the watch that pushed the Sea-Dweller concept to extreme depths. Rolex engineered the Ringlock system — a nitrogen-alloyed steel inner ring paired with a domed sapphire crystal and caseback — to withstand enormous pressure without increasing the case diameter beyond wearable proportions. At 44mm wide and 17.7mm thick, it wears like a true instrument piece built for saturation diving professionals.

Key Specifications

The 116660 Up Close: Case, Dial and Bracelet

The 44mm Ringlock case gives the Deepsea its commanding wrist presence. The domed sapphire crystal, measuring 5.5mm thick, is noticeably raised above the bezel plane — a visual indicator of the engineering beneath the surface. The helium escape valve at nine o’clock vents accumulated gas during decompression.

On the matte black dial, oversized Chromalight indices and a bold minute track optimize underwater legibility. The “DEEPSEA” text in green sits above the depth rating, distinguishing this model from the standard Sea-Dweller at a glance.

The Oyster bracelet includes Rolex’s Glidelock system for up to 20mm of fine extension without tools — ideal for wearing over a wetsuit. Browse related references in the Deepsea collection.
