With its octagonal bezel with softened angles, its case construction inspired by a porthole and its dial with struck horizontal relief, the Nautilus has embodied, since 1976, the elegant sport style par excellence. Forty years later, it is available in a vast collection of men's and ladies' watches, in steel, pink gold, white gold or two-tone versions, accompanying the most active lives with class.
