The in 2010 released Patek Philippe Annual Calendar is one of the modern-day annual calendars Patek is producing. A story that started in 1996 with the ref 5035.

The 5205 uses a mechanical self-winding movement housing a day, date and month in apertures. Moon phases and 24-hour display. Sweep seconds hand. An in my opinion gorgeous two-tone dial and gold applied hands.

The 40mm case is available in white gold and yellow gold. All of which are placed on a hand-stitched alligator strap with gold prong buckle.
