Estimate: € 200.000 –⁠ 400.000

When it debuted in 1941, the Patek Philippe reference 1526 was far more than a technical innovation—it was a declaration of intent. As the world’s first serially produced perpetual calendar wristwatch, the 1526 marked a turning point in horological history, introducing collectors and connoisseurs to a new era of wrist-worn mechanical sophistication. Offered here is an exceptionally rare variant of this already extraordinary model: a pink gold example, one of only a handful among the approximate 210 total pieces ever made—most of which were cased in yellow gold. The case remains in great condition, its elegant curves fully intact and the hallmarks still clearly visible. The soft, warm hue of the pink gold is elevated by the presence of a matching period, exquisitely made mesh bracelet. This watch carries a compelling narrative. In the early 1990s, it entered the market fitted with a custom diamond dial, a decision made by a previous owner in keeping with the trends of that era. Its original character seemed lost—until a later owner sourced a beautiful, period-correct dial. This dial, with an elegant patina earned through time, restored the watch to its historically faithful configuration. With its blend of technical importance and aesthetic beauty, this reference 1526 is a chapter in the story of high horology. This is a timepiece that resonates as a watch for the collector who values legacy as much as craftsmanship.
