The Patek Philippe Annual Calendar Yellow Gold Cream Dial 39mm ref. 5146/1J-001 presents a quiet refinement that continues the Geneva brand’s legacy of calendar innovation. Introduced in 2005, the 5146 is powered by the calibre 324 S IRM QA LU automatic movement, offering annual calendar functionality that only requires adjustment once a year. The 39mm case and integrated bracelet are crafted entirely from 18K yellow gold, matched elegantly with a cream lacquered dial featuring applied gold hour markers. Subdials display the day and month at 12 o’clock and the moon phase with date at 6 o’clock, while a power reserve indicator sits discreetly between 10 and 11 o’clock. With 35 to 45 hours of power reserve and 30 meters of water resistance, this reference balances complications and wearability. The 5146/1J-001 stands as a staple for collectors seeking a classic Patek Philippe annual calendar in full precious metal.
