Patek Philippe Calatrava ref.570 in Yellow Gold, Antimagnetic

Few dress watch designs can rival the enduring classicism of Patek Philippe’s Calatrava line. This Ref. 570, considered a truly oversized watch in its time, already measured 35mm in the 1930s, an assertive and fashion-forward statement on the wrist by the standards of the era.

This small-seconds example is powered by the rare Caliber 27-400AM, an antimagnetic movement typically reserved for Patek Philippe’s dedicated “antimagnetic” models, such as references 2570 and 3417. Introduced in 1960, the 27-400AM is equipped with Patek Philippe’s signature Gyromax balance and a Breguet hairspring, designed specifically to withstand high electromagnetic environments. The choice of this distinctive movement underscores the special story behind this particular watch.
