3448J CartierRef

Debuting in 1962, the Patek Philippe 3448 was the first self-winding perpetual calendar watch globally. It was produced until the early 1980s, eventually being succeeded by the 3940, with approximately 586 units manufactured, primarily in yellow gold. This 1968 piece is notable for its Cartier-signed dial, while versions in alternative metals like platinum or white gold remain exceptionally rare and valuable.
