In 1996, Patek Philippe introduced their patented annual calendar wristwatch the reference 5035, a practical yet complicated mechanism that considered the different lengths of the months and required only one annual adjustment in February. In 2010, the brand released their first annual calendar Nautilus, the reference 5726.

Initially launched with a grey dial and fitted on a leather strap, the reference 5726A/1A-001 featured a well-proportioned 40.5mm case and perfectly symmetrical dial layout with two apertures at 12 o’clock indicating the day and month. At 6 o’clock, the moon phase and 24-hours are indicated via a subsidiary dial with an aperture indicating the date below, inspired by the brand’s vintage perpetual calendar models. A second generation annual calendar Nautilus was launched in 2012 paired with a matching stainless steel Nautilus bracelet and stunning white dial with contrasting black markers like the present reference 5726/1A-010. Today, Patek Philippe’s annual calendar Nautilus with blue dial (014) is still offered within their collection.

The present example is a wonderful representation of this milestone timepiece. The watch is offered in excellent condition with its Certificate of Origin and presentation box. This is a rare opportunity to own one of these exceptional wristwatches.
