Overview
The Annual Calendar in a row of apertures
The Patek Philippe Complications Annual Calendar, Moon Phases, reference 5205R-011, in rose gold with a sunburst olive green dial and black-gradient rim, on a hand-patinated two-tone green alligator strap. Self-winding calibre 26-330 S QA LU 24H with day, date and month in apertures, moon phases and 24-hour indication; 40 mm, 11.36 mm high.
The rose gold execution carries a sunburst olive green dial with a black-gradient rim, which Patek Philippe presents as an original, contemporary shade, with faceted rose gold dauphine-style hands and applied hour markers and a rose gold frame beneath the date aperture, on a hand-patinated two-tone green alligator strap with a rose gold prong buckle.
The reference 5205 is Patek Philippe's Annual Calendar with moon phases in the Complications collection, recognisable, as the brand puts it, by its three day, date and month apertures set along the arc of a circle. The case is 40 mm across and 11.36 mm high, polished, with recessed flanks, skeletonised lugs and a concave bezel.
The self-winding calibre 26-330 S QA LU 24H carries the brand's Annual Calendar mechanism, which Patek Philippe describes as invented and patented by Patek Philippe: the day, date and month are shown in apertures and advance on their own, so the calendar needs correcting once a year, at the end of February. A 24-hour indication and the moon phases share a sub-dial at 6 o'clock, with sweep seconds from the centre. The movement measures 32.6 mm across and 5.8 mm high, with 339 parts and 34 jewels, winds through a 21K gold central rotor, runs at 28,800 semi-oscillations an hour on a Gyromax® balance with a Spiromax® balance spring, has a power reserve of 35 to 45 hours, and carries the Patek Philippe Seal.
For collectors
Patek Philippe calls this the everyday complication: a full day-date-month display with one correction a year, in a case the brand describes as understated and contemporary.
