As the reinterpretation of a design icon, the Ref. 5811/1G-001 Nautilus features a case and bracelet in white gold as well as a blue sunburst dial with a black gradation to the periphery.

Water-resistant to 30 m and with a slightly enlarged diameter to 41 mm, the watch reflects its affinity with the original Nautilus of 1976 with a two-part case. It also features several subtle technical refinements and patented innovations: a secured fold-over clasp, a new lockable adjustment system, and a new pull-out piece lever system that replaces the split stem.
