Patek Philippe Nautilus Annual Calendar 40.5mm 5726A-001 – Black Dial

Patek Philippe Nautilus Annual Calendar 40.5mm 5726A-001 – Black Dial

Patek put the annual calendar into the Nautilus case in 2010, which meant fitting day, date, month and a moon phase onto an embossed dial without losing the model's horizontal rhythm. The answer was three apertures in a row under twelve and a subdial at six carrying the moon phase and a 24-hour scale. This version runs on a leather strap rather than the bracelet, and the 40.5mm steel case keeps the porthole bezel.

2021 with original papers; presentation box included.
