Reference 3448 is a worthy heir to Patek Philippe’s long lineage of perpetual calendars which commenced with reference 1526. A pivotal watch in the history of horology, the latter was the very first serially produced perpetual calendar wristwatch that was launched in 1941. Reference 3448 was Patek Philippe’s first self-winding perpetual calendar wristwatch and was introduced in 1962. The watch was fitted with the new in-house calibre, the 27-460Q, which was patented by the firm. Furthermore, the caliber bears the prestigious Geneva seal underlining the painstaking hand finish it has gone through.

According to literature, 586 examples were manufactured during its 20 years of production. It is interesting to note that this watch was manufactured at the very first stages of the reference 3448 production run. With the series starting with movement number 1’119’000, the present watch is the 80th example ever made.

Early generation models feature all black printing (signature and date ring) in raised hard enamel. The outer minute marks are small gold "pearls" giving the watch an undeniably vintage look.

The rarity and desirability of this milestone piece is further enhanced by the Gübelin signature beneath the moonphase indicator. Founded in Lucerne in 1854, Gübelin was then as now, one of the most exclusive retailers of fine horology.

The present watch is being offered to the market only for the second time since its manufacture, and is accompanied by its original Patek Philippe Certificat d'Origine et de Garantie, underlining the quality of this piece and care it has been given. It is a superbly preserved example of one of Patek Philippe’s finest creations offering rarity, refinement, condition, and most importantly, pleasure on the wrist.
