The Grand Complications 3448J Cartier, seen from the bench

The Patek Philippe 3448J represents the pinnacle of perpetual complications. Launched in 1962 and produced until 1981 in only 586 examples, this Grand Complication features a 37mm yellow gold case housing a rare automatic movement with perpetual calendar, moon phases, and day, month, and leap year indication. The watch requires a strap worthy of its rarity and craftsmanship.
