Designed by Gerald Genta, the Nautilus was one of the first luxury sports watches brought to market, an enduring icon of contemporary 70s design. In 1981, Patek Philippe released a smaller version of the iconic original, the reference 3800. It was more than just a compact iteration mirroring the pristine aesthetic language. Functional developments occurred with the addition of a central second hand—and what made it all tick. This watch was powered by an all-new in-house automatic caliber 330 SC movement. Altogether, the 3800 was a groundbreaking development for the Nautilus, and a commitment to expanding its identity and reach. With all original parts and this particular 3800 in yellow gold and with a stunning blue dial, embodies the brand's majesty. Further, this rare example comes with a factory set diamond bezel, and diamond hour markers directly from Patek Philippe. It also comes with a one year Material Good warranty.
