This rarity from Patek Philippe is a ladies’ watch made in 1940. The reference 1252 Chameleon is a hinged bangle bracelet watch in 18k pink and yellow gold, with a pink (or salmon) dial. Only three examples are known publicly. The two other are both made entirely in yellow gold, and one of those two resides in the Patek Philippe Museum in Geneva.
