Patek Philippe 3520 Calatrava 18k 1970s

Minimalism, Perfected — The White Gold Calatrava in Its Purest Form

Elegant, ultra-thin, and architecturally balanced, this Patek Philippe Calatrava Ref. 3520/12 from the 1970s is a true embodiment of timeless design. Crafted in 18k white gold with a seamless lugless case and integrated bracelet, it exemplifies Patek’s minimalist mastery at its most refined.

The untouched silver sunburst dial radiates quiet sophistication, paired with slender baton hands and Patek’s signature understated charm. The beautifully woven white gold bracelet offers a soft drape on the wrist — as much fine jewelry as it is precision watchmaking.

Inside, the hand-wound Caliber 175 delivers classic mechanical performance in an ultra-slim 5.2mm case. This reference is a rare and wearable expression of the Calatrava philosophy: purity, proportion, and enduring elegance.
