Technical Specifications: Movement: Caliber 324 S QR, self-winding mechanical movement Complications: Perpetual calendar with retrograde date, moon phases, leap year indicator Case: rose gold with sapphire crystal caseback Display: The retrograde date hand sweeps across a 180-degree arc before instantly jumping back to the beginning of the month Power Reserve: Approximately 45 hours Notable Features: The retrograde mechanism adds exceptional visual appeal to the perpetual calendar function. Unlike traditional date displays that advance incrementally, the retrograde hand creates a graceful arc across the dial before its dramatic return to position one. The perpetual calendar automatically accounts for varying month lengths and leap years until the year 2100, requiring no manual adjustment during this period. The moon phase indication maintains accuracy for 122 years before requiring a one-day correction. Historical Context: This reference exemplifies Patek Philippe’s mastery of complex complications, representing decades of horological refinement. The combination of perpetual calendar and retrograde display demonstrates the manufacture’s ability to merge technical prowess with aesthetic sophistication.
