The Rolex Deepsea, a titan in the world of professional diving watches, commands attention not only for its robust functionality and impressive water resistance but also for its substantial case thickness. Measuring a considerable 17.7 mm, it's a far cry from the slim profiles of everyday timepieces. This article delves into the reasons behind this impressive thickness, exploring the engineering choices that contribute to its legendary performance and examining the different models within the Deepsea lineage. We’ll also consider the implications of this thickness on wearability and the overall aesthetic of the watch.
The 17.7 mm thickness isn't simply a matter of aesthetics; it's a testament to the engineering prowess required to achieve the Deepsea's remarkable 3,900-meter (12,800-foot) water resistance. While most standard wristwatches comfortably sit within the 8 to 12 mm thickness range, the Deepsea's significantly larger dimensions are directly linked to its ability to withstand the immense pressure at such extreme depths. This pressure, roughly 400 times that at sea level, necessitates a robust case construction capable of preventing water ingress and maintaining the watch's internal integrity.
Let's examine the specific models and their shared commitment to this substantial thickness:
Rolex Deepsea Oyster 44mm Oystersteel: This flagship model, often simply referred to as the Rolex Deepsea, embodies the brand's commitment to robust engineering. Its 44mm case diameter, combined with its 17.7 mm thickness, creates a watch that is undeniably substantial on the wrist. The Oystersteel construction, a proprietary stainless steel alloy, contributes to both the watch's durability and its weight. The thickness isn't just about the case itself; it accommodates the complex internal mechanisms required for reliable performance under extreme pressure. This includes the reinforced crystal, the Triplock crown, and the helium escape valve, all contributing to the overall dimensions.
Rolex Deepsea DWELLER 44mm: While the nomenclature might suggest a subtle difference, the Rolex Deepsea DWELLER 44mm shares the same impressive 17.7 mm thickness as its sibling. The name "Dweller" emphasizes the watch's suitability for saturation diving, a technique involving extended periods spent at depth. This demanding application necessitates a watch capable of enduring even greater pressure and stress, reinforcing the need for the substantial case dimensions. The design choices, including the robust case construction and the inclusion of the helium escape valve, directly contribute to the watch's overall thickness.
Rolex Sea-Dweller Deepsea 126660: This model, often referred to as the "126660," represents a refined iteration of the Deepsea concept. While maintaining the crucial 17.7 mm thickness, Rolex has subtly refined the design, improving ergonomics and wearability without compromising the watch's essential functionality. The focus on refinement underscores that the thickness isn't simply a consequence of poor design; it's a necessary characteristic for achieving the required level of water resistance and durability.
