Reference 3448 was first released in 1962 with production continuing for approximately 20 years. As the successor to the 2497 and 2438-1, the 3448, with its more angular design, represented a departure from the classic rounded cases and lugs of previous complication references. This was a reflection of the change in wristwatch design more generally, which was evolving during the 1960s and 1970s. The 3448 was not only the first automatic perpetual calendar made in series by Patek Philippe, but the first by any company. An iconic model, the 3448 is one of the most distinctive of all Patek Philippe’s perpetual calendar models and can be seen as a bridge between the watchmaker’s early series produced perpetual calendar wristwatches and the more modern examples that followed it.
