1963 Patek Philippe Ref.3433 Step-design 36mm Water-resistant Automatic Very rare "Rose gold"

A highly rare 18K rose gold model from 1963, the Patek Philippe Ref. 3433 features a 36mm waterproof automatic step-design case. This popular model inherits the elegance and durability of the step-design screw-back waterproof case from the Ref. 2551, which is equipped with the Caliber 12-600AT. A total of 490 pieces were produced at the time, with 400 in yellow gold, and 30 each in rose gold, white gold, and platinum. Among these, the rose gold model is the rarest on the market. Beyond its rarity, the excellent preservation of the rose gold case, which retains its original shape, and the silver dial with its thick enamel coating, further enhance the uniqueness of this piece. It comes with the archive papers.
