Introduced in 1962, the Patek Philippe reference 3448 marked the world’s first serially produced self-winding perpetual calendar wristwatch. Fewer than 600 examples are believed to have been made across all metals, with this timepiece distinguished by its pearl minute divisions, crisp printed graphics and larger date ring. Another standout detail? The dial bears the coveted Tiffany & Co. signature—reflecting the historic partnership between Patek Philippe and Tiffany & Co., which dates back to 1851.
