Patek Philippe Annual Calendar Moonphase 5205R-011 | Rose Gold

A Legacy of Annual Calendar Mastery

Patek Philippe’s Annual Calendar is one of the Maison’s most important modern signatures — a patented solution that elegantly reconciles mechanical memory with everyday practicality. This 5205R-011 in warm 18k rose gold and olive-green dial embodies that heritage, offering seasonal intelligence with an unmistakable Patek pedigree.

The Curator’s Insight

The Annual Calendar is a triumph of practical ingenuity — it remembers the varying lengths of months (except February) so the wearer need only correct it once a year. Translating that subtle mechanical intelligence into a slim, wearable form is an art that Patek perfected long ago.

The Ultimate Heirloom of Innovation

This 5205R-011 is more than a utility; it is a living chapter of Patek Philippe’s inventive story. It marries the technical milestone of the Annual Calendar with refined materials and dial execution, producing a timepiece that reads as effortlessly on the wrist as it does on paper. For the collector in search of continuity — an object to wear now and hand down later — this is a direct line to the Maison’s modern genius.
