The Rolex Sea-Dweller, a watch synonymous with deep-sea exploration and robust reliability, underwent a significant evolution in 2014 with the introduction of the reference 116600. This model, often referred to as the SD4000 (Sea-Dweller 4000), marked a return to the classic 40mm case size after a period dominated by larger Sea-Dweller models. This seemingly subtle change represented a deliberate move by Rolex, re-establishing a balance between the iconic design language of the original Sea-Dweller and the advanced technological capabilities expected of a modern professional diving watch. This article will explore the history of the Rolex 116600, examining its design, specifications, market performance, and legacy within the wider context of Rolex's dive watch lineage.
A Return to Roots: Design and Specifications
The 116600’s most significant departure from its predecessors lay in its 40mm case diameter. Previous Sea-Dwellers, particularly the Deepsea, had ventured into larger dimensions, catering to a preference for more substantial wrist presence. However, the 116600 consciously reverted to the more manageable 40mm, appealing to a broader range of wrist sizes and echoing the dimensions of the original Sea-Dweller models, thereby establishing a strong connection to the watch's heritage.
Despite its smaller size, the 116600 didn't compromise on functionality. It maintained the impressive water resistance of 1220 meters (4000 feet), a testament to Rolex's mastery of waterproof case construction. This remarkable depth rating, combined with the robust Oyster case, ensured the watch could withstand the extreme pressures of deep-sea diving. The unidirectional rotating bezel, a crucial element for safe diving, featured a Cerachrom insert, a highly scratch-resistant ceramic material developed by Rolex, guaranteeing long-term accuracy and legibility. The luminescent Chromalight display ensured excellent visibility even in low-light conditions, a critical feature for underwater use.
The movement powering the 116600 was the calibre 3135, a workhorse movement known for its reliability and precision. This self-winding mechanical movement, with its Parachrom hairspring and Paraflex shock absorbers, provided exceptional resistance to shocks and magnetic fields. The calibre 3135's robust design and proven track record contributed to the 116600's reputation for dependability. It featured a power reserve of approximately 48 hours, offering ample timekeeping capability even when the watch wasn't being worn.
