Patek Philippe Nautilus 3700/1A 'Jumbo' Stainless Steel Blue Dial

The Patek Philippe Nautilus 3700/1A, nicknamed the “Jumbo,” is the original reference that launched the Nautilus line in 1976. Designed by Gérald Genta, it features a 42mm stainless steel case with its signature porthole-inspired design and integrated bracelet, marking a bold departure from traditional dress watches of the era.

The blue dial, with its horizontal ridges and applied white gold hour markers, has become one of the most iconic in watchmaking history. Slim at just 7.6mm thick, the 3700/1A houses the ultra-thin automatic caliber 28-255 C. Revered by collectors, the 3700/1A set the foundation for the luxury sports watch category and remains one of the most important and collectible Patek Philippe references of the 20th century.
