The foundational Patek Philippe Calatrava — with an unexpected link to the American motor industry. Introduced in 1932, the reference 96 marks the origin point: the first Calatrava, and a model that would define the brand’s design language for decades to come. Produced for over 40 years, its restrained proportions, three-piece case and time-only display established a template that became emblematic of understated refinement. Always read the caseback. This circa 1955 example carries an added layer of intrigue: a “GM Photographic” engraving. Such markings, often overlooked, can reveal a life beyond the manufacture — in this case, a connection to General Motors’ Photographic division, established in 1920 and responsible for documenting nearly a century of American industrial and cultural history.
