For sale: pre-owned Rolex Sea-Dweller ref. 126660 DeepSea black dial, with full set. The oyster perpetual rolex deepsea in oystersteel with a cerachrom bezel insert in black ceramic and an oyster bracelet. It features a black dial and large luminescent hour markers. Waterproof to a depth of 3,900 metres (12,800 feet) with a unidirectional 60-minute rotatable bezel, the Rolex deepsea is amongst the ultra-resistant divers’ watches engineered by rolex for deep-sea exploration. Rolex seemed to want the new for 2018 reference 126660 to look similar to the outgoing 116660, so it kept one of the original Deepsea’s most controversial features. That is a silver rehaut ring around the dial which contains two phrases being “Original Gas Escape Valve” (referring to the automatic helium release valve) and “Ring Lock System,” which refers to how the case is constructed to ensure such high levels of water resistance. The silver ring itself is actually part of the Ring Lock and is a “high-performance nitrogen-alloyed stainless steel ring.”  The modern Rolex sports watches, in particular, are renowned for their solidity—their ability to weather the harsh beatings that often come with everyday wear and the Sea-Dweller is part of this group. They use the toughest steel on cases and bracelets, their bezels are forged from practically unbreakable ceramic and they have movements with an inherent strength, not only from their physical size, but also from components made from revolutionary materials.
