SUMMARY

Rolex’s hardcore dive instrument, the Deepsea Sea-Dweller, was first introduced in 2008 and showcases the Geneva watchmaker’s technical achievements. More than tripling the depth capabilities of the standard Sea-Dweller, its waterproofness is rated at 12,800 feet / 3,900 metres. This is thanks to several engineering achievements, including a 5mm thick sapphire crystal, a helium escape valve, and a Ringlock system. 

This particular example benefits from some key technical, and aesthetic updates, which Rolex introduced in 2018 on the model reference 126660. The case was slightly refined for a better fit, and the lug width was increased slightly, from 20 to 22mm, to accommodate for a wider bracelet to provide a sturdier fit. A new movement was also fitted - the calibre 3235, which offers 70 hours of power reserve, anti-magnetic construction, and Rolex’s Chronenergy escapement. This latest iteration is now rated beyond COSC certification and is accurate from -2 to +2 seconds per day.
