Aquanaut Annual Calendar — Rose Gold

Introduced in 1997, the Aquanaut was Patek Philippe's second sports watch, a more casual counterpart to the Nautilus, with a rounded octagonal case and composite strap. The manufacture has since extended the line into grand complication territory, including annual calendar and moonphase references.
