Listed at $11,772 (at the time of writing, prices fluctuate), it commands a premium price reflecting its heritage, engineering prowess, and enduring appeal. This article will delve into the specifics of the 2018 Deepsea Sea-Dweller, comparing it to its predecessors, exploring its investment potential, and examining its place within the broader Rolex Sea-Dweller family.
The 2018 Rolex Deepsea Sea-Dweller (126660): A Closer Look
The 126660 distinguishes itself from its predecessor, the 116660, through several key improvements. Most notably, the introduction of Rolex's in-house Calibre 3235 movement represents a significant technological leap. This movement offers improved accuracy, power reserve (approximately 70 hours compared to the 116660's 48 hours), and enhanced shock resistance. The updated movement is also equipped with the Chronergy escapement, a silicon escape wheel that contributes to the watch's overall reliability and precision. The inclusion of the Chronergy escapement is a hallmark of Rolex's commitment to pushing the boundaries of horological engineering.
Beyond the movement, the 2018 model retains the iconic Deepsea aesthetic: a 44mm Oystersteel case capable of withstanding immense water pressure (to a depth of 3,900 meters/12,800 feet), a unidirectional rotating bezel with a Cerachrom insert for scratch resistance, and a robust Oyster bracelet. The Triplock crown system further enhances the watch's water resistance, ensuring its reliability in the most demanding underwater environments. The sapphire crystal, scratch-resistant and highly legible, protects the dial, which typically features a black matte finish with luminous hour markers and hands for optimal visibility in low-light conditions.
Rolex Deepsea 116660 vs 126660: A Comparative Analysis
The transition from the 116660 to the 126660 represents a natural evolution in Rolex's Deepsea line. While both watches are capable of extreme depths, the 126660 offers superior performance and longevity thanks to the upgraded Calibre 3235 movement. The increased power reserve is a significant advantage, particularly for divers who might be working in remote locations without easy access to winding equipment. The improved accuracy and shock resistance contribute to the watch's overall reliability and make it a more robust and dependable tool watch. Aesthetically, the differences are subtle, with the primary distinction lying in the movement and the resulting enhanced performance.
