Annual Calendar Reference 5205, with its day/date/month apertures arranged along the arc of a circle, was launched in 2010 as two white gold versions. In 2022, Patek Philippe revisits this model in an original and contemporary color. The case is distinguished by its concave bezel, its hollowed flanks and its skeletonized lugs. This refined architecture is entirely hand-polished by the artisans of the Manufacture. The olive green dial is enlivened by a sunburst motif and by a black gradient around the rim. The day/date/month apertures in the upper part ensure perfect readability of the Annual Calendar indications, with a rose gold frame at 12 o’clock accentuating the most important item of information, the date. The transparent sapphire crystal enables one to admire self-winding Caliber 324 S QA LU 24H, equipped with the ingenious patented Patek Philippe Annual calendar mechanism requiring only one manual adjustment per year, at the end of the month of February.
