3448J BraceletRef

The Patek Philippe 3448, launched in 1962, represented a significant achievement as the brand's inaugural automatic perpetual-calendar wristwatch. By the early 1980s, it was supplemented by the 3450, which included a leap-year indicator, before both were largely succeeded by the 3940 in 1985. The specific 1978 model presented here, sourced from an Antiquorum auction, includes an integrated bracelet characteristic of that era.
