A Calatrava like you rarely see.
This Patek Philippe ref. 3591, produced around 1971, embraces pure minimalism: a sunburst blue dial, highlighted by white Roman numerals and two slim hands. Nothing superfluous, just the essentials.

Inside beats the caliber 28-255, an ultra-thin automatic movement. All housed in a 33 mm yellow gold case, paired with an integrated solid gold bracelet (adjustable from 195 to 185 mm), with a total weight of 91 g.

A watch that is simple, rare, and timeless — exactly what a Calatrava should be.
