Patek Philippe 30-255

The Patek Philippe 30-255 is a manual-winding movement introduced in 1960 as part of the in-house Caliber 30 family. It represents a vintage large-format caliber that reflects Patek Philippe's mid-century approach to movement design for dress and complications watches. The movement was discontinued but remains notable within the brand's historical catalogue as an example of their 1960s-era in-house development.
