The groundbreaking Patek Philippe reference 3448 is the premiere of the self-winding perpetual calendar wristwatch by the maison at the time of launch in 1962. Refined in its execution, the triple calendar with moon phases design features modern contour of a circular case design with satisfying angular razor-sharp lugs by Antonie Gerlach—casemaker who specialise for Calatrava cases, and was given the Italian nickname “Padellone” or large frying pan. During its two decades of production until 1985, approximately 586 examples were produced for the “Padellone” with 450 examples cased in yellow gold. The model was made in four series with its distinctive details for each evolution.

The first series (1962-1965) features small calendar ring, indexes closer to the center of the dial and engraved/enamelled minute divisions.

The second series (1965-1972) introduces pearled minute divisions.

The third series (1971-1978) maintains the pearled divisions but introduces the large numerals for the date rings and indexes closer to the outer edge of the dial.

The fourth series (1981- end of production) exemplified by the present example - features printed minute divisions.

A combination of rarity, timeless aesthetics and historical importance, the present Patek Philippe ref. 3448 in 18K yellow gold fitted with English calendar exhibits an attractive overall condition boasting an unpolished case and defined lugs. Furthermore the present lot is accompanied with the Patek Phillipe Extract from the Archives confirming its date of manufacture in 1981 which corresponds to the production of the beginning of the fourth series. Highly sought after in the market and praised by the most celebrated collectors, it is a formidable timepiece with an important place in the respected heritage of Patek Philippe.
