Patek Philippe Calatrava 2533 Double Signed

A double-signed Patek Philippe Calatrava 2533 from the early 1950s – a timepiece that breathes history and carries a patina that only decades of authentic aging can create.

Breathtaking Patina – a Work of Nature
The highlight of this watch is undoubtedly its spectacularly aged dial. The warm, shimmering, organically developed patina was formed through decades of interaction between the dial surface and the radium lume on the hands and markers. This pattern cannot be reproduced or imitated – it exists only where time, materials and history have worked together in perfect harmony.

Double-Signed – Shreve, Crump & Low
This example becomes even more special thanks to the additional retailer signature on the dial: Shreve, Crump & Low, the historic Boston jeweler founded in 1796, making it one of the oldest jewelry houses in North America. Only a small and exclusive group of retailers were allowed to place their name alongside Patek Philippe’s on the dial – and accordingly, these double-signed watches are exceptionally rare and highly coveted.

Reference 2533 – Sporty, Elegant, Pioneering
Reference 2533 is the direct successor to the iconic 565 and represents Patek’s sporty Calatrava of the early 1950s. Its 34.5 mm case with screw-down back makes it one of the very few waterproof Calatravas of its time. The slightly stepped bezel and beveled lugs give the watch a subtle yet powerful presence – a perfect balance of elegance and sporty refinement.

An Authentic Overall Impression
The 18k yellow gold case displays a beautiful patina – precisely the kind of honest aging that true collectors prefer to preserve rather than polish away. The engraving on the caseback adds another chapter to the personal history of this watch – a quiet reminder of the life and moments it has witnessed.

Inside ticks the reliable hand-wound Patek Philippe calibre 27SC – a movement renowned for its precision and reliability.

The Patek Philippe Extract from the Archives has already been requested and will be handed over to the future owner.

This exceptional 18k yellow gold Calatrava is one of those rare moments when you instantly feel: a watch is more than an object. It is a moment of time, preserved forever.
