Often referred to by collectors as the \u003cstrong\u003e“Disco Volante”\u003c\/strong\u003e for its distinctive broad, stepped “flying saucer” case profile, the reference 2551 represents one of the most elegant early automatic designs produced by Patek Philippe during the 1950s.\u003c\/p\u003e\n\u003cp\u003eThis particular example is especially desirable for its \u003cstrong\u003edouble-signed Patek Philippe \/ Gübelin dial\u003c\/strong\u003e. Gübelin, founded in Lucerne in 1854, was one of Switzerland’s most prestigious jewelers and an important historic retailer of Patek Philippe watches. Much like Tiffany \u0026amp; Co. retailer-signed Pateks, period Gübelin-signed examples were produced in significantly smaller numbers than standard dials and are particularly sought after by collectors today. The silvered dial features applied gold hour markers, an applied Arabic numeral at 12, elegant dauphine hands and central sweep seconds, with the discreet GÜBELIN retailer signature positioned beneath the Patek Philippe signature.\u003c\/p\u003e\n\u003cp\u003eInside is one of the great movements of post-war Swiss watchmaking: Patek Philippe’s calibre 12-600 AT, a 30-jewel automatic movement and the manufacture’s first self-winding calibre. Beautifully finished throughout, it features the unmistakable 18K gold winding rotor, Gyromax balance and Geneva Seal finishing. The architecture and workmanship of the 12-600 AT are a major part of the appeal of these early automatic Pateks and make the movement nearly as impressive to look at as the watch itself.\u003c\/p\u003e\n\u003cp\u003eThe movement is numbered 764XXX, while the 18K case is numbered 2601XXX and correctly stamped Patek Philippe \u0026amp; Co. Genève, Swiss, 0.750, Ref. 2551 inside the case back. The corresponding case and movement numbers are consistent with production in approximately 1957.\u003c\/p\u003e\n\u003cp\u003eAdding considerably to its appeal, this watch comes \u003cstrong\u003edirectly from the original owner\u003c\/strong\u003e and has survived in remarkably honest, unmolested condition. The 18K yellow-gold case retains its original character and strong stepped profile without the softened edges commonly seen on heavily polished vintage Pateks. The watch also retains its desirable \u003cstrong\u003eearly double-P signed crown\u003c\/strong\u003e, an important period detail that is frequently lost over decades of servicing.\u003c\/p\u003e\n\u003cp\u003eThe dial, hands, case and movement remain beautifully preserved with the natural character expected of a nearly 70-year-old watch. Rather than having been cosmetically restored to appear new, it presents as a genuinely well-preserved vintage Patek with the originality and character increasingly prized by serious collectors. The watch is currently running and keeping time. It is fitted with a high-quality later leather strap.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Details:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCirca: \u003cstrong\u003e1957\u003c\/strong\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eReference: \u003cstrong\u003e2551J\u003c\/strong\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eCase Size: Approximately \u003cstrong\u003e36mm\u003c\/strong\u003e excluding crown\u003c\/li\u003e\n\u003cli\u003eCase: \u003cstrong\u003eSolid 18K yellow gold, 0.750\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eCase Number: \u003cstrong\u003e2601XXX\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eMovement: \u003cstrong\u003ePatek Philippe calibre 12-600 AT, 30 Jewel\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eMovement Number: \u003cstrong\u003e764XXX\u003c\/strong\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eAutomatic winding with \u003cstrong\u003e18K gold rotor\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eDial: \u003cstrong\u003eSilvered dial, double-signed Patek Philippe \/ Gübelin\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eRetailer: \u003cstrong\u003eGübelin, Lucerne, Switzerland\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eHands: Period gold dauphine hands with central sweep seconds\u003c\/li\u003e\n\u003cli\u003eCrown: \u003cstrong\u003eEarly double-P Patek Philippe signed crown\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eCondition: \u003cstrong\u003eUnpolished, highly original and honestly preserved\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eProvenance: \u003cstrong\u003eAcquired directly from the original owner\u003c\/strong\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eStrap: High-quality leather strap, later replacement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eA rare opportunity to acquire an \u003cstrong\u003eearly automatic Patek Philippe Calatrava with a desirable Gübelin double-signed dial\u003c\/strong\u003e, original-owner provenance and the legendary calibre 12-600 AT.
