Built for the Deep – A Watch Like No Other

Rolex introduced the Sea-Dweller collection in 1967 as a tool watch for professional deep-sea divers. Over the years, Rolex has pushed the boundaries of innovation, and the Deepsea model remains the ultimate expression of extreme diving capabilities.

✔ Waterproof to 3,900m (12,800ft) – A record-breaking achievement
✔ Developed in collaboration with COMEX – A watch made for professionals
✔ Tested in extreme conditions – Rolex’s in-house deep-sea pressure testing ensures reliability

Oystersteel Case – Strength Under Pressure

The 44mm Oystersteel case is built to withstand immense underwater pressure, thanks to Rolex’s exclusive Ringlock System.

✔ Grade 904L Oystersteel – Corrosion-resistant and exceptionally durable
✔ Ringlock System – A patented case architecture that withstands deep-sea pressures
✔ Helium Escape Valve – Developed for saturation diving, allowing trapped gases to be released safely
✔ Screw-down Triplock Crown – Triple waterproofing for maximum security

This is not just a watch—it’s a survival instrument, designed for the bravest underwater explorers.

The Deepsea Black Dial – Maximum Readability in the Abyss

Underwater visibility is crucial for professional divers, and Rolex has designed the Sea-Dweller Deepsea 136660 with an ultra-legible black dial that remains clear even in the darkest depths.

✔ Chromalight Display – Long-lasting blue luminescence for superior readability in low-light conditions
✔ Bold hour markers and Mercedes hands – Designed for instant time-telling underwater
✔ Date window at 3 o’clock – A subtle yet useful feature

Rolex’s anti-reflective sapphire crystal ensures that the dial remains crystal-clear at all times, whether you're hundreds of meters underwater or standing on dry land.

Unidirectional Ceramic Bezel – Precision and Control

The Cerachrom bezel insert is made from Rolex’s proprietary ceramic, ensuring that it is scratch-resistant, fade-proof, and nearly indestructible.

✔ 60-minute graduated scale – Essential for tracking dive times accurately
✔ One-way rotation – Prevents accidental adjustments during dives
✔ Platinum-coated numerals – Enhanced legibility in all environments

The bezel is an essential tool for divers, providing a safe and accurate way to measure elapsed time underwater.

Oyster Bracelet – Comfort Meets Security

A high-performance diving watch demands a high-performance bracelet, and the Oyster bracelet on the Deepsea 136660 delivers just that.

✔ Oysterlock Clasp – Prevents accidental opening
✔ Glidelock Extension System – Allows adjustments of up to 20mm in 2mm increments, no tools needed
✔ Fliplock Extension Link – Extends the bracelet an additional 26mm to fit over a diving suit

Whether worn over a wetsuit or directly on the wrist, this bracelet ensures a secure and comfortable fit in any situation.
