The Aquanaut combines a modern sporty character with Patek Philippe's refined watchmaking. This 42.2mm model features a khaki green dial with the signature embossed Aquanaut pattern and matching khaki green composite strap. The white gold case is finished with polished and satin-brushed surfaces, while the self-winding movement provides central hours, minutes, seconds and date display. The watch is powered by the Calibre 26-330 S C and features a sapphire crystal case back.
