7 Patek Philippe An extremely rare and attractive, Antimagnetic, wristwatch in yellow gold, retailed by Somazzi, with extract from the archives, reference 2570/1.

Estimate: € 50.000 –⁠ 100.000

To collectors of refined tastes and horological depth, the present reference 2570/1 offers a glimpse into a chapter of Patek Philippe history that remains largely unknown to the wider public—yet deeply coveted by connoisseurs. In an era when antimagnetic watches were deemed purely utilitarian and typically cased in humble steel, Patek Philippe had the audacity to transcend the functional and elevate the form. With only around sixteen known examples of the Amagnetic reference 2570/1 cased in yellow gold, this watch stands among the rarest variants ever produced by the Geneva firm. Even more remarkably, this piece is the only known specimen, to the best of our knowledge, to feature the Somazzi retailer signature, one of those small details that turns rarity into uniqueness. The “Amagnetic” inscription, combined with applied gold indexes and the large 12, 3 and 9 all contribute to a dial that is as elegant as it is historically significant. While references 2570 and 2570/1 may appear nearly identical at a glance, the refined crown integration and sculpted downturned lugs of the 2570/1 confer a subtle sophistication and improved wrist presence. Preserved in remarkable condition, the watch is accompanied by an Extract from the Archives confirming its manufacture in 1958 and its sale in May 1959. To the informed eye, it is not merely a timepiece, but a rare document of Patek Philippe’s ability to blend technical foresight with aesthetic restraint.
