Patek Philippe 3520 Calatrava 18k 1970s

A Dress Watch Classic Refined to Perfection - Patek Philippe Calatrava 3520

Over the decades, Patek Philippe has redefined timeless elegance through its Calatrava line — and this Ref. 3520 is no exception.

Housed in a 32.5 mm 18k yellow gold case, this model is defined by its clean bezel and elegant lugs. The crisp silver sunburst dial and slim baton hands give it a sense of calm, refined symmetry.

Powered by the ultra-thin manual Caliber 175, this Calatrava embodies understated luxury. And to complete the experience, it comes with the original Patek Philippe strap and matching Patek Philippe 18k gold buckle — rarely seen together after decades.

With its slender profile, flawless dial, and unmistakable Patek DNA, this watch is not just timeless — it's eternal.
