Reference 3700/1 marks the origin of one of the most influential luxury sports watches ever created: the Nautilus by Patek Philippe. Introduced in 1976 and designed by the legendary Gérald Genta, the model revolutionized high watchmaking by elevating stainless steel to the status of precious metal within haute horlogerie. Its distinctive porthole-inspired case with rounded octagonal bezel and integrated bracelet established a new aesthetic language: sporty yet elegant, bold yet refined, that continues to define the genre today. The reference 3700/1, often nicknamed the “Jumbo,” is especially prized for its design, ultra-thin automatic movement, and historical importance as the inaugural Nautilus generation.
The present example, crafted in steel and preserved in incredible condition, represents a particularly rare opportunity for collectors. The case retains sharp edges, while the bezel and integrated bracelet display exceptional surface definition. The dial remains beautifully preserved, showing the characteristic horizontal relief pattern and applied indexes with outstanding clarity.
Of notable importance, this watch is offered as a complete full set, accompanied by its original cork box and original guarantee. Examples of the reference 3700/1 preserved in such remarkable condition and retaining their original accessories are seldom encountered, making this piece a highly desirable acquisition for collectors.
