Launched in 1997 with a young, new generation of watch lovers in mind, the Aquanaut pays homage to the iconic Nautilus with a rounded octagonal case while embodying the modern spirit of sporty chic. This reference 5168 features a large white gold case that houses a self-winding mechanical movement that can be admired through its sapphire crystal case back. Within the case is the embossed dial in a new khaki green color, a fresh addition to the Aquanaut family that was typically seen with black dials. In combination with the matching khaki green rubber strap which had become a collector’s item in itself, this effortlessly stylish watch makes the perfect everyday timepiece.
