A pre-owned Rolex Submariner watch is easily one of the undisputed icons of horology and widely regarded as the most famous dive watch of all time and one of the most desirable watches in the world. Its enduring appeal stems from a potent combination of robust functionality, timeless design, and a rich history steeped in exploration and adventure. A significant chapter in this history involves the enigmatic acronym COMEX, often found subtly etched on the dial or caseback of certain vintage Submariners. Understanding the meaning and significance of COMEX on a Rolex watch unveils a fascinating story of collaboration, innovation, and the extreme limits of human endurance.
Rolex COMEX: The History of a Mythical Watch
The COMEX (Compagnie Maritime d'Expertises) was a French commercial diving company renowned for its pioneering work in saturation diving. Saturation diving, a technique where divers live in pressurized environments for extended periods, allows for significantly longer underwater work durations. This method was crucial for undertaking complex and lengthy offshore projects, particularly in the challenging conditions of the North Sea. COMEX pushed the boundaries of underwater exploration, demanding equipment capable of withstanding the immense pressures and rigorous demands of this pioneering field.
In the late 1960s and throughout the 1970s, COMEX collaborated with Rolex to develop and test watches capable of enduring the extreme conditions of saturation diving. This wasn't merely a marketing exercise; it was a genuine partnership born out of a mutual need for reliable, high-performance timekeeping instruments. Rolex, already established as a manufacturer of robust and accurate watches, saw this collaboration as an opportunity to further refine and test the limits of its diving watches. The partnership resulted in a series of specially modified Submariner models, often referred to as “COMEX Submariners,” that became legendary for their resilience and accuracy in the most demanding underwater environments.
These COMEX Submariners featured several key distinguishing characteristics that set them apart from standard production models. While the exact specifications varied across different iterations, some common features included:
* Helium Escape Valve: This crucial addition, also known as a HEV, allowed helium gas to escape from the watch case during decompression. During saturation diving, divers breathe a helium-oxygen mixture, and the helium atoms can become trapped within the watch case during the ascent. Without a helium escape valve, the pressure difference could cause the crystal to shatter or the case to deform. The presence of a HEV is a defining characteristic of COMEX Submariners.
* Special Dial Markings: Many COMEX Submariners featured unique dial markings, often including the COMEX logo itself, sometimes subtly integrated into the design. These markings served as a clear indicator of the watch's special purpose and its connection to the pioneering work of COMEX.
* Unique Caseback Markings: Similar to the dial, the caseback often featured specific engravings denoting the COMEX collaboration. These markings served as a form of authentication and further emphasized the watch's unique history.
