The Ref. 5811/1G-001 Nautilus is a reinterpretation of a design icon, featuring a white gold case and bracelet, and a blue sunburst dial with a black gradation to the periphery. The watch is water-resistant up to 120 meters and has a diameter of 41mm, slightly larger than the original Nautilus from 1976. The two-part case includes several patented innovations, including a secured fold-over clasp, a new lockable adjustment system, and a new pull-out piece lever system that replaces the split stem.

The watch is powered by a self-winding mechanical movement, caliber 26-330 S C, and includes a date in an aperture and sweep seconds. The sunburst blue dial features horizontally embossed gold hour markers with a luminescent coating. The white gold case includes a screw-down crown and a sapphire crystal case back, and is 8.2mm in height. The watch comes with a white gold strap and a patented fold-over clasp with a lockable adjustment system.
