Few watches have altered the course of modern watchmaking as decisively as the Patek Philippe Nautilus. Introduced in 1976, the Reference 3700 marked a radical departure for the manufacture. It was sporting, stainless steel, and unapologetically contemporary. It was the first Nautilus ever made, and in time, it would become one of the most important wristwatches in history.

Originally conceived solely in steel, the 3700 was later reinterpreted by Patek Philippe in yellow gold, a subtle but significant evolution that underscored the strength of Gerald Gentas design. The form remained intact. The same porthole case, the integrated bracelet, the disciplined geometry, but the material shifted the tone from pure sport to something more nuanced and luxurious.

This example represents an exceptionally rare chapter within that story: the Reference 3700/13J, fitted with a factory diamond-set bezel. Produced in extremely limited numbers, it reflects a moment when Patek Philippe explored the outer edges of the Nautilus concept while maintaining its essential restraint. The diamonds do not overwhelm the design; instead, they introduce a subtle contrast. It is precision meeting ornament, sport meeting ceremony.

Preserved in excellent condition with very minor wear, this watch retains its clarity and presence, carrying only the lightest traces of time. A foundational reference, elevated by rarity, it stands as both a historical artifact and a quietly confident expression of one of watchmakings most enduring designs.
