Early 1990s Patek Philippe Nautilus 3800/1JA Two-Tone – Mid-Size Icon

This Patek Philippe Nautilus Ref. 3800/1JA represents the perfectly balanced mid-size evolution of Gérald Genta’s iconic design. Crafted in a rare two-tone combination of stainless steel and 18k yellow gold, the 37.5 mm case delivers sportiness with unmistakable elegance.

The ribbed golden sigma dial is flawless, framed by the signature rounded octagonal bezel and complemented by an integrated two-tone bracelet for exceptional comfort. Inside ticks the ultra-thin automatic Caliber 330 SC, combining precision with a slim profile.
