Patek Phillippe’s groundbreaking reference 3448 was launched in 1962 as the world's first self-winding perpetual calendar wristwatch, replacing the earlier manually wound perpetual references 1526 and 2497. Today, it is one of the most coveted models due to its symmetry, harmony and robust Calatrava-style case produced by Antione Gerlach. The exquisite caliber 27-460 Q (“Q” for Quantiême) was built on Patek Philippe’s first automatic caliber 12-600 introduced in 1953. After almost two decades in production, in 1981 the brand replaced the 3448 with the reference 3450 featuring a leap year indicator, which was later disconnected in the mid-1980s, replaced by the reference 3940.

Nicknamed the “Padellone” by Italian collectors, the reference 3448 is adored by collectors for its oversized, 37.5 mm diameter case with clean, angular lines and the symmetrical and balanced dial. The way in which the wide bezel slopes dramatically outwards from the dial, with jutting angular lugs, gives the impression of a watch much larger than its actual case measurements. Later examples, such as the current lot, feature more uniform and modern print for the signature and date track.

The present example is in lovely condition, and was factory serviced in 2019, and since then remained sealed until opened for catalogue photography. The model is one of Patek Philippe’s finest creations and is an icon within horological circles. Freshly serviced, it is certain to impress those who wear it.
