The Patek Philippe Calatrava was introduced in 1932 with the ref. 96, establishing the round, minimalist dress-watch design that would become one of the maison’s defining signatures. Inspired by Bauhaus principles, the Calatrava focused on clean lines, balanced proportions and elegant simplicity. Named after the Calatrava Cross found in Patek Philippe’s emblem, the collection evolved through countless references, materials and dial designs, while always remaining true to the same understated philosophy. More than 90 years later, the Calatrava remains one of the great icons of classic Swiss watchmaking — a perfect example of the idea that sometimes, less really is more. Here we have a lovely and rather rare ref. 2591, featuring a snap-back case measuring 34.5 mm and wonderfully concealed lugs. The combination gives the watch a slightly UFO-like, or “Disco Volante”, appearance — a particularly charming characteristic of this reference. The watch is fitted with a fine winding crown and a beautifully serene, sunburst-finished gold dial, featuring elegant applied stick markers, a raised enamel Patek Philippe signature and slender stick-style hands. But the detail that really makes this one special is the subtle yet important double-signed “Beyer” signature on the lower half of the dial. Beyer Zürich is one of those names that has been quietly woven into the history of Swiss watch collecting for generations. The story began in 1760, making Beyer the oldest specialised watch retailer in Switzerland. Founded by the Beyer family, the business remained family-owned for more than 250 years and became one of the most respected names in Swiss watch retail. The company established itself on Zürich’s Bahnhofstrasse in the late 19th century, a location that would become synonymous with Beyer and its reputation for fine watches and jewellery. Over the generations, Beyer developed close relationships with some of Switzerland’s most important watchmakers, including Patek Philippe, Rolex, IWC and Breguet. For collectors, a Beyer-signed receipt, box, certificate or retailer stamp can therefore add a wonderful piece of provenance to a vintage watch. And there is another reason the name Beyer is so special to watch enthusiasts: beneath the store is the Beyer Clock and Watch Museum, home to an impressive collection tracing the history of timekeeping across the centuries. More than just a retailer, Beyer has become part of Zürich’s horological history itself — a family business that has been selling, servicing and celebrating fine watches since 1760. Patek Philippe has agreed to acquire Beyer Chronometrie in Zürich. The Beyer store at Bahnhofstrasse 31 is scheduled to close at the end of 2026, with the premises set to become a Patek Philippe Salon from the beginning of 2027. Back to our Beyer Patek.
