The Nautilus self-winding watch, model number 5726/1A, is now available with a new blue dial that gradually fades to black around the edges. This dial color is inspired by the original Nautilus watch from 1976, giving it a classic and sophisticated look. The steel case is water-resistant up to 120 meters and features an Annual Calendar and moon-phase display. The movement of the watch consists of 347 parts and can be viewed through the sapphire crystal case back.

The dial also includes gold hour markers with a luminescent coating, and a 24-hour indication. The strap is made of steel and has a patented fold-over clasp with a lockable adjustment system. The case measures 40.5 mm in diameter and is 11.3 mm in height.
