Rolex Sea Dweller Deep Sea Black-blue/Steel Ø44 mm

For the deep-sea explorations, Rolex has assured it'll never be led by any. For over a decade now, Rolex Sea Dweller 116660 DB model has progressively remained iconic amongst
professional divers with its attributes which have even exceeded the expected. To ensure the Rolex DeepSea watch is noncorrosive in the harsh saltwater, its outer casing is of sturdy 904L
stainless steel and titanium. Then added with a Ring lock mechanism and helium escape valve to ensure it can withstand the extreme underwater pressure of 390 bars without malfunctioning. To enhance readability in the dark sea-depths, Rolex Sea Dweller 116660 DB has its D-Blue dial lighted with a long lasting luminesce. This applies to the unidirectional rotating bezel as well which has a Chromalight capsule on the zero marker.
