The 3700 is the original Patek Philippe Nautilus, designed by Gerald Genta in 1976 — four years after his Royal Oak. Often called "Jumbo" for its 42mm porthole-inspired case. Production ran until 1990 and the design language defined every Nautilus that followed. Steel 3700s have become some of the most coveted vintage references in modern collecting.
