  • Catalogue Essay

    In 1996, Patek Philippe patented the Annual Calendar complication, a new mechanism that took into account the different lengths of the months and required only one annual adjustment in February. The legibility of the calendar functions were made easy thanks to the month and day that were indicated via two apertures on the top part of the dial whereas the date, moon phases and 24 hours indication were placed elegantly on the lower part of the dial.

    In a bold move, Patek Philippe decided to merge fine complications and sports chic by launching a Nautilus housing this intelligent and useful complication.

    The present reference 5726/1A-010 is the second variation of the Annual Calendar Nautilus launched in 2012, which, for the first time was offered with the iconic Nautilus satin and mirror finished stainless steel bracelet.

    Until the recent presentation of the reference 5740 perpetual calendar, reference 5726 was the most complicated Nautilus model.

    Housed in the immediately recognizable case designed by Gerald Genta with a fair 40.5 millimeter diameter, this annual calendar movement displays its indications on a beautiful white dial.

    This example presented with its factory double seal is rare and more compelling.
