An important Asian collection since 2010 Alan Banbery’s Unique Leap Year Indication Reference 3448J A collector’s dream and one of the stars of an important private collection for over a decade, Christie’s is greatly honoured to present to the world’s most discerning collectors the exceptional opportunity to acquire a timepiece of almost mythical status. Of immense historical and horological significance, the present watch is surely one of the most legendary wristwatches associated with Patek Philippe and it is offered here with the same sense of excitement that accompanies the appearance of any world-class work of art at auction.

Alan Banbery’s yellow gold 3448 perpetual calendar wristwatch can be described, without exaggeration, as one of the most famous wristwatches in the world. So famous in fact, that it is now unquestionably within the pantheon of Patek Philippe’s greatest historic timepieces. To the true connoisseur of important vintage wristwatches, the mere mention of the name ‘Banbery’ brings the unmistakable and instantly recognizable minimalist aesthetic of this unique reference 3448 immediately to mind.

A legend in his own lifetime, Alan Banbery was, apart from the Stern family themselves, perhaps the key figure at Patek Philippe in the second half of the 20th century – one of the most exciting and crucial periods of the company’s history. The present reference 3448 was Alan Banbery’s personal watch for almost 25 years, indeed the case back is engraved with his monogram ‘AB’. Unsurprisingly for a figure of such immense stature at Patek Philippe, Banbery’s wristwatch is no ‘ordinary’ reference 3448 but a completely unique piece that was specially adapted for him in Patek Philippe’s workshops in 1975. Furthermore, this watch was presented directly to Alan Banbery by the family-run Patek Philippe company’s owners, the great Henri and Philippe Stern. What makes Alan Banbery’s Reference 3448 Unique and Important? The Alan Banbery wristwatch is a stand-alone watch among all reference 3448s. Entirely unique and exquisitely good looking, it is the only fully provenanced, fully documented, specially commissioned example of a so-called ’Senza Luna’, it is also the only ‘Senza Luna’ to have a leap year indication. As such it is highly important both as a key part of Patek Philippe’s history and as part of the company’s experimentation with technical and aesthetic developments in the mid-1970s. The reference 3448 automatic perpetual calendar is always highly desirable as one of Patek Philippe’s great classic models of the 1960s and 70s, a total of only 586 pieces were made over an almost 20 year production period. Whilst the model’s stunning aesthetic, clean lines and scarcity have ensured its eternal popularity, the standout feature of the 3448 is its prominent moon phase indication. However, there are seven recorded examples of the reference, including the present watch, which exist without the moon phases. These seven fabled and enigmatic watches have become known as ‘Senza Luna’ or ‘Without Moon’. All the ‘Senza Luna’ 3448s were originally made with the moon phase function and aperture but were subsequently remodelled in Patek Philippe’s workshops either by special request or as prototypes. Set apart from all other ‘Senza Luna’ 3448s is Alan Banbery’s watch which has the unique mechanical conversion to permit the display of a leap-year indication. The mechanical conversion work for the leap-year function is recorded as being done by Patek Philippe’s master watchmaker Max Berney. Berney removed the moon phase disk and modified the movement so that a leap year indication could be displayed with a corresponding small hand. The dial was uniquely adapted by Stern Frères as a special order at the request of Patek Philippe by creating a new subsidiary dial displaying leap year.

In presenting this highly individual watch to Alan Banbery, probably to celebrate his 10 years with the company, Patek Philippe were recognizing Banbery’s achievements and devotion to the firm. Additionally, from a commercial point of view, the Sterns knew that the fact that this watch would be seen on Alan Banbery’s wrist as a brand ambassador would certainly create great curiosity and intrigue among Patek Philippe collectors, perhaps inspiring them to own something similar.

Dial The solid gold dial was made by Stern Frères in 1969-1970 and modified again by Stern Frères in 1975 at the request of Patek Philippe in order to close the moon phase aperture and replace it with the unique

subsidiary dial for the leap-year indication. The engraved-enamelled signature and date of the subsidiary dial are still completely original and beautifully raised. The leap year indication inside the date, instead of the moon phases, and its sector are in red, printed by transfer, the technique that was used in the mid-1970s. The “silky” dial surface texture and colour matches perfectly with the best quality dials made by Stern Frères for Patek Philippe. Named ‘satinéopalin’ it is especially seen on these complicated references including 3448s or 2499s. For the present watch, a special set of hands has been made to overlay the indication of the leap year and the date from the same axis. Case The well-preserved case was made by master casemaker Antoine Gerlach and delivered in November 1969, it is constructed in three pieces in 18K yellow gold with snap-on bezel and back. The elongated triangular and faceted lugs were welded to the case, date correctors and hand-forged winding crown (with the ‘Calatrava’ pattern) in yellow gold. The central part of the case is horizontally brushed, the full bezel and bevelled periphery of the exterior of the case-back are mirror polished. The centre of the case back is engraved with the famous ‘AB’ monogram for Alan Banbery. Movement Made in 1969, calibre 27 460 Q (Q for Quantième), Gyromax balance, stamped twice with the Geneva Seal, modified by Max Berney, Master Watchmaker at Patek Philippe.

We are grateful to Eric Tortella for his assistance and study in researching this watch. 40-year career with the company. A career which saw him become one of the most influential figures in the development not only of Patek Philippe’s market position but also in the company’s commitment to the preservation and acquisition of historic Patek Philippe watches and other horological masterpieces. To this end, Philippe Stern installed Alan Banbery as keeper of Patek Philippe’s private collection, the nucleus of which reflected his father Henri Stern’s love of fine enamel work. For Philippe Stern, collecting the best examples of the world’s greatest watches and clocks became a fascination. With Alan Banbery’s guidance in making acquisitions, the collection became so outstanding that it culminated in the opening of the Patek Philippe Museum in Geneva in 2001, after which Alan Banbery retired. In 1982, Alan Banbery along with Martin Huber had published the first academic book on Patek Philippe pocket watches. In 1988 it was followed by a volume on Patek Philippe wristwatches (featuring the present watch on pages 220-221). Both publications are sought after as important reference works to the present day.

Alan Banbery’s illustrious career with Patek Philippe spanned one of the most fascinating periods in the development and evolution of the wristwatch. Working closely with Philippe Stern, the two men steered Patek Philippe safely through the turbulent waters of the 1970s with their unwavering commitment to excellence in Patek Philippe’s products. This philosophy combined with a strong buying presence in the auction rooms from the 1980s onwards enhanced Patek Philippe’s reputation immeasurably, thus ensuring the company’s future and its position today at the very pinnacle of the finest watchmaking.
