The Patek Philippe 5327G-001 is a self-winding perpetual calendar watch that combines classic elegance with sophisticated functionality. Housed in a 39mm white gold Calatrava case, it features a royal blue sunburst dial with gold applied Breguet numerals. The watch displays day, date, month, leap year, and 24-hour indications via hands, along with a moon phase complication. Powered by the ultra-thin Caliber 240 Q movement, it offers a power reserve of 38 to 48 hours. The timepiece is complemented by a hand-stitched, shiny navy blue alligator strap with a fold-over clasp.
