The term "Tauchverlängerung," German for "diving extension," refers to the ingenious bracelet extension system found on certain professional diving watches, notably the Rolex Deepsea. This article delves into the intricacies of the Rolex Deepsea's Tauchverlängerung, comparing it to other diving watches, exploring the Rolex Deepsea's capabilities and history, and examining the market for these coveted timepieces. We will also consider alternative options, such as Seiko's impressive line of professional diving watches.
Rolex Deepsea Watches: A Legacy of Depth
The Rolex Deepsea, specifically the reference 116660, is a titan among diving watches. Its robust construction, water resistance to an astounding 3,900 meters (12,800 feet), and innovative features make it a benchmark for professional diving instruments. At the heart of its impressive capabilities lies the Ringlock System, a patented internal structure that reinforces the case and contributes significantly to its immense water resistance. This system, combined with the Triplock winding crown and helium escape valve, ensures the watch can withstand the crushing pressure of the deepest ocean trenches.
The Rolex Deepsea's Tauchverlängerung is an integral part of this professional design. This cleverly engineered extension system allows divers to adjust the bracelet's length over their bulky diving suit, ensuring a comfortable and secure fit even in extreme conditions. The extension mechanism is typically integrated seamlessly into the clasp, allowing for quick and easy adjustment without the need for tools. This functionality is crucial for divers who need to wear their watches over thick neoprene gloves or dry suits, maintaining the watch's position on the wrist during decompression stops and ascents. The ease and speed of adjustment are paramount in emergency situations, where a secure, comfortable fit can be the difference between safety and risk.
The history of the Rolex Deepsea is closely tied to the exploration of the deep ocean. Its development was influenced by decades of Rolex's experience in producing robust and reliable diving watches, culminating in the creation of a watch capable of withstanding the pressures encountered in extreme underwater environments. The Deepsea's design philosophy is one of uncompromising durability and precision, making it a highly sought-after timepiece for both professional divers and watch enthusiasts alike.
Rolex Deepsea Challenge: Pushing the Boundaries
The Rolex Deepsea's exceptional depth rating is not merely a marketing claim. It's a testament to its rigorous testing and proven performance. The Rolex Deepsea Challenge, a special edition of the Deepsea (although not featuring the standard Tauchverlängerung), played a significant role in demonstrating its capabilities. This watch, attached to the submersible *Deepsea Challenger*, accompanied James Cameron on his record-breaking solo dive to the Challenger Deep, the deepest point in the Mariana Trench. The watch successfully withstood the immense pressure at a depth of over 10,900 meters (35,755 feet), a testament to Rolex's engineering prowess and the watch's exceptional durability. This expedition highlighted not only the watch's incredible depth rating but also the importance of reliable timekeeping in extreme environments. While the Deepsea Challenge was a special project, it showcased the technological foundation upon which the standard Deepsea's impressive depth rating and robust design are built.
