Sea-Dweller Deepsea M116660

Released in 2008, the Rolex Sea-Dweller Deep Sea served as the replacement for the regular Seadweller until the introduction of the Seadweller 4000 in 2014. It features a heavy stainless steel case of 44mm with a titanium insert in the caseback. Another notable change is the crystal, which is domed instead of flat - resembling the look of the old 1665's.
