Manufactured in 1958, this rare Patek Philippe Ref. 3415 features the renowned Caliber 12-600AT, a waterproof automatic movement, housed in an 18k rose gold case. This model is particularly notable as it is one of the rare references equipped with Patek Philippe’s first in-house automatic movement, the Cal. 12-600AT. Of the approximately 370 pieces produced, the majority were in yellow gold, while only about 40 are believed to have been made in rose gold, making this a truly exceptional find.
The seemingly simple dial design is uniquely crafted with a combination of applied and engraved indices—an element scarcely seen even among vintage Patek watches, further enhancing this piece's rarity. The 35mm screw-back waterproof case, equipped with the legendary Cal. 12-600 movement, makes this an excellent choice for a vintage watch that can be enjoyed daily. The watch is accompanied by an archive extract, adding to its appeal and collectability.
