About this watch
The Rolex Sea-Dweller 16600T is a masterclass in luxury watch design and engineering. Its stainless steel case measures 40mm in diameter, with a robust build that can withstand the pressures of deep-sea diving. The black dial features luminous markers for excellent visibility, even in darkness. A rotating bezel adds to the watch's rugged aesthetic while serving as a practical tool for timing dives. Protected by scratch-resistant sapphire crystal, this timepiece is built for durability and precision. At its heart lies the Rolex caliber 3135 self-winding mechanical movement, certified as a Swiss chronometer by COSC. This movement boasts enhanced resistance to shocks and temperature variations courtesy of its Parachrom hairspring, ensuring accuracy and reliability. With a power reserve of 48 hours, you can enjoy worry-free wear. The Sea-Dweller's water resistance of 1220 meters (4000 feet) makes it an ideal choice for serious divers. Its unique blend of functionality and elegance has earned this watch a place in horological history.
