Embracing its rich seafaring heritage, Ulysse Nardin presents the newest pearl in the Diver line, bringing together the best of its ocean-faring timepieces. One of the distinguishing characteristics of a Diver Black Sea is its stainless case coated with vulcanised rubber. Not only does this vulcanisation process enhance the timepiece's comfort and flexibility, it multiplies its ability to withstand extreme conditions. The rubber extends to the unidirectional turning bezel, with a rubberised screw crown for added water-resistance to depths of 200m. Diver Black Sea adds sporting style to its chronometric precision: studding the bezel with white ceramic stones that offer a striking contrast to the black rubber. Due to the 3S technique — an exclusive stone-setting process developed with a specialist — ceramic stones exhibit a brilliance like never before.
