Rare 1960s steel Patek Philippe Calatrava, Ref. 3509. Simple yet elegant, this vintage Patek has a silvery white dial with black printed Roman numerals (which is less common than Ref. 3509 with applied hour markers). 

Its 33mm case is made of stainless steel, making it inherently rare given Patek did not make many references in steel compared to precious metals. It has a smooth and wide bezel and a screw-down case back, which is another attractive feature that is found on a smaller scale in vintage Patek’s production.

Powered by hand wound caliber 23-300. Fitted with its PP steel tang buckle.
