Patek Philippe 12-600

Caliber 12-600 is a manual-winding, in-house movement introduced by Patek Philippe in 1950 as part of the caliber 12 family. Designed as an ultra-thin dress watch caliber, it reflects the manufacturer's mid-20th century emphasis on elegant, refined movements. The movement was discontinued. It remains notable as an example of Patek Philippe's approach to creating exceptionally slim movements for formal timepieces.
