The Rolex Deepsea reference 136660-0005, widely known as the James Cameron edition, is a high-performance luxury dive watch featuring a 44mm Oystersteel case and a distinctive D-blue gradient dial that fades from twilight blue to pitch black. This model commemorates James Cameron’s historic solo dive to the Mariana Trench and is engineered with the patented Ringlock System, allowing it to withstand extreme pressures at depths of up to 3,900 meters. The watch is equipped with a unidirectional rotatable bezel featuring a black Cerachrom ceramic insert, a 5.5mm-thick domed sapphire crystal, and an RLX titanium caseback to manage weight without compromising structural integrity.
At the heart of the timepiece is the self-winding caliber 3235 movement, which offers approximately 70 hours of power reserve and a precision of -2/+2 seconds per day. The watch features center hands for hours, minutes, and seconds, along with an instantaneous date window at the 3 o’clock position that has been enlarged by approximately 8% in this reference for better legibility. It also includes a helium escape valve, essential for decompression during saturation diving, and a stop-seconds function for precise time setting. The integrated Oyster bracelet utilizes the Glidelock extension system, allowing for fine adjustments over a diving suit.
General reviews of the 136660-0005 frequently praise its technical over-engineering and the striking aesthetic of the gradient dial. Enthusiasts often highlight the improved proportions and the removal of the Fliplock extension as refinements that make the large 44mm case more comfortable for daily wear than previous generations. However, critics often note its substantial thickness of 17.7mm and overall weight, which may be prohibitive for those with smaller wrists or a preference for discreet timepieces. Despite its size, it is widely regarded as a pinnacle of dive watch engineering and a significant collector’s piece due to its association with deep-sea exploration.
