The Chaumet Class One is the benchmark in "sport chic”, with its unusual combination of "marron glacé" rubber and stainless steel, making it the perfect luxury diving watch. Notice the unidirectional rotating bezel with black numerals. The round dial with Roman numerals has a subtle fine-brushed sunray pattern with Class One guilloche. The Roman numerals and markers are rhodium applied and luminescent. It closes with a folding clasp buckle. It's Swiss made and water resistant to 100 meters.
