At Baselworld 2010, Patek Philippe unveiled reference 5950, a cushion-shaped, single-button split-seconds chronograph, reimagined with subtle Belle Époque styling. The model holds several surprises for collectors, most notably its casing: a Grand Complication executed in stainless steel.
Production of reference 5950A was exceptionally limited, reserved strictly as an "application watch" for Patek Philippe’s top clientele and our research indicates that fewer than 20 examples have ever appeared at public auction. The present lot is preserved in exceptional condition and comes complete with its full suite of original accessories, including an interchangeable solid caseback adorned with the same corner scroll engravings seen on the dial.
Complicated stainless steel Patek Philippe wristwatches represent the pinnacle of horological collecting. The reference 5950A occupies a category of its own as one of the most compelling modern creations from the manufacture—a status famously affirmed when noted scholar and collector John Goldberger selected this exact reference for the cover of his landmark book, Patek Philippe Steel Watches.
