The Patek Philippe 2552 Calatrava, affectionately known among collectors as the 'Disco Volante,' stands as one of the most intriguing mid-century automatic dress watches produced by the maison. Crafted in the 1950s, this reference was the debut model for Patek’s groundbreaking automatic caliber 12-600 AT, regarded for its exceptional finishing, large rotor, and enduring reliability. Its 18K yellow gold case, measuring a notable 36mm, features an unmistakable broad, flat bezel and revered stepped profile—attributes that earned the model its 'flying saucer' nickname. The silver dial, accented by applied gold baton indexes and a subsidiary seconds indicator at 6 o’clock, represents the mid-century elegance and minimalism for which the Calatrava line is celebrated. Highly sought after for its early automatic movement, scarce production, and unique design, the 2552 sits at a critical inflection point in Patek Philippe’s horological evolution. Today, the Disco Volante is prized by connoisseurs for its technical significance, sophisticated presence, and pivotal role in the history of self-winding wristwatches.
