Built around a 40mm round stainless steel case, the Sea-Dweller 16600 features a black dial, sapphire crystal, solid case back, and a screw-in crown. The no-holes case is an F-series example and comfortably fits a 7.75-inch wrist.
Water resistance is rated to 1200 meters / 4000 feet, making it one of the more capable depth ratings in Rolex's Oyster lineup. The stainless steel bracelet is secured by a folding Oysterlock safety clasp with Rolex's Glidelock extension system for a precise fit.
The automatic movement includes a date complication. This watch is offered in mint condition and includes the Rolex box and booklets.
