ANNUAL CALENDAR. MOON PHASES.
An Annual Calendar in steel
Patek Philippe has combined the "sporty elegant" style of its Nautilus with the comfort and ingenuity of its patented Annual Calendar requiring only one manual correction per year. The three day/date/month apertures, complemented by a 24-hour indication and moon phases, stand out in a very legible and balanced way on the charcoal gray dial with its black-gradient rim.
