Lot Essay
With Patek Philippe Extract from the Archives confirming production of the present watch in 1971 and its subsequent sale on September 30th of the same year.
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. Predominantly encased in yellow gold, examples in white gold are more rare and thus far only one example in rose gold is known
Reference 3448 was fitted with the celebrated calibre 27-460, amongst the most sophisticated 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 (Quantime Bissextile) calibre. The model differs from its predecessor by the modified leap year indication, the eccentric small window to 4 o'clock.
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 M. Huber & A. Banbery, second edition, p. 288
