Few vintage watches combine with the greatest of ease the charm of past generation watchmaking and the real pleasure of wearing a contemporary self-winding perpetual calendar wristwatch in such a subtle manner like the white gold reference 3448. Its architectural design, great readability and discreet appearance make it an ideal companion, be it for formal or casual occasions. It is therefore by no surprise that it is one of the most coveted collector's wristwatches and considered one of Patek Philippe's ultimate thoroughbred complications.
Reference 3448, introduced into the market in 1962, was at the time the first self-winding perpetual calendar wristwatch. According to literature, a total of 586 examples were made, the majority in yellow gold cases (see lot 363 in this auction). Few watches have been cased in white gold and only two examples in platinum are known to date.
Reference 3448 was fitted with the celebrated calibre 27-460, amongst the most sophisticated and lavish automatic movements ever made. It was later upgraded with Patek Philippe's patented perpetual mechanism fitted on the movement plate underneath the dial and renamed 27-460 Q.
In 1981, reference 3450 was introduced into the market with the improved 27'460 QB (Quantième Bissextile) calibre. The model differs from its predecessor by the modified leap year indication, the eccentric small window to 4 o'clock. The first series was made with a simple red disk and Arabic numerals, the second with Roman I, II, III and IIII leap year indication.
A total of 244 examples of reference 3450 (see lot 185 in this auction) were made, the majority in yellow gold cases, only two in white gold are known to date.
Production of both reference 3448 and 3450 was discontinued in 1985 when reference 3940 was launched.
Reference 3448 is illustrated in Patek Philippe Wristwatches by Martin Huber & Alan Banbery, second edition, p. 288 and in Ore d'Oro by Jader Barracca, Giampiero Negretti and Franco Nencini, p. 45.
