The Rolex 136660-0003, also known as the Deepsea, is a true masterpiece of horology. It is a timepiece specifically designed for deep-sea divers and professionals who need a reliable and accurate instrument on their wrist while exploring the ocean s depths.
The case of this watch is made of Rolex s patented Oystersteel, highly resistant to corrosion and extremely durable. The diameter of the case measures 44mm, making it a perfect fit for most wrist sizes. The case architecture features the unique Rolex Ringlock System, designed to withstand extreme pressure at great depths. This system also includes a helium escape valve, allowing any helium that may have entered the watch during deep-sea diving to escape safely.
The bezel of the 136660-0003 is unidirectional and rotatable, with a 60-minute graduated scale, and features a scratch-resistant Cerachrom insert made of ceramic. The numerals and graduations are coated in platinum, providing a stunning contrast against the black background and ensuring legibility in low-light conditions.
The winding crown is screw-down, equipped with the Triplock triple waterproofness system, which ensures the watch is water-resistant to depths of up to 12,800 feet or 3,900 meters. The crystal is made of scratch-resistant sapphire, known for its durability and clarity.
The dial of the 136660-0003 is deep blue and features luminescent hour markers and hands, making it easy to read in any lighting condition. The date window is located at the 3 o clock position and features the Cyclops lens, which magnifies the date display by 2.5 times for easier reading.
The movement of the 136660-0003 is powered by Rolex s in-house Caliber 3235, a self-winding mechanical movement featuring a paramagnetic blue Parachrom hairspring and a power reserve of approximately 70 hours. The movement is also COSC certified, having passed the rigorous testing standards set by the Swiss Official Chronometer Testing Institute.
