The Rolex Sea-Dweller 4000, produced from 2014 to 2017, holds a unique place in the brand's illustrious history. This transitional model, bridging the gap between the iconic 16600 and the current generation Sea-Dweller, offered a compelling blend of classic design and enhanced functionality. While its successor, the current Sea-Dweller, boasts a larger 43mm case, the SD4000 remains a sought-after timepiece for its refined proportions and impressive depth rating. This article will delve into the specifics of the Rolex SD4000 size, exploring its dimensions, design elements, and place within the broader context of Rolex's diving watch legacy.
Rolex Sea-Dweller 4000 Dimensions: A Perfect Balance of Size and Functionality
The defining characteristic of the Rolex SD4000, in relation to its predecessors and successors, is its 40mm case size. This dimension strikes a balance between the more compact 40mm case of the previous generation Sea-Dweller (ref. 16600) and the larger 43mm case of the current model. This makes the SD4000 appealing to a wider range of wrist sizes, offering a comfortable fit without sacrificing the watch's robust functionality.
The 40mm case diameter refers to the measurement across the bezel, excluding the crown. The overall dimensions, however, are slightly larger due to the presence of the crown guards and the slightly curved lugs. While precise lug-to-lug measurements vary slightly depending on the specific watch and measurement technique, a typical figure falls around 47-48mm. The thickness of the watch, including the crystal and case back, is approximately 13mm, adding to its substantial feel on the wrist.
The case itself is constructed from 904L stainless steel, a highly corrosion-resistant alloy favored by Rolex for its superior durability and resistance to scratches and tarnishing. This material contributes to the watch's exceptional longevity and its ability to withstand the pressures of deep-sea diving. The polished surfaces of the case are meticulously finished, reflecting light beautifully and adding to the watch's overall elegance.
Rolex Oyster Sea-Dweller 4000: The Legacy of a Diving Icon
The Rolex Sea-Dweller 4000 is a member of Rolex's esteemed Oyster line, a testament to the brand's commitment to waterproofness and reliability. The Oyster case design, first introduced in 1926, is characterized by its robust construction, featuring a screw-down crown and case back, ensuring complete water resistance. The SD4000's Oyster case, with its Triplock winding crown, provides exceptional protection against water ingress, contributing to its impressive 1200m (4000ft) water resistance rating.
This depth rating is a significant feature of the SD4000, highlighting its professional diving capabilities. It's crucial to understand that this rating isn't simply a marketing claim; it reflects rigorous testing and engineering to ensure the watch's ability to withstand extreme underwater pressure. The robust construction of the case, the secure sealing of the crown and case back, and the use of a sapphire crystal contribute to the watch's exceptional water resistance.
