Centennial calendar complication watch改3-24 movement mechanical watch

The Patek Philippe perpetual calendar moon-phase watch centers on a complex Caliber 324 movement driving day, date, month, and lunar displays across a clean mechanical dial. A mechanical case construction supports the multi-function layout, uniting traditional horological complications with legible presentation. Designed for collectors who value enduring calendar automation, it pairs refined finishing with the quiet prestige of a complication-driven wristwatch.
