Patek Philippe Calatrava 570

Manufactured between 1938 and 1972, this model was nicknamed Big Calatrava because its case size of 35 mm was slightly larger in those days. It shares a design concept with a model that robustly finished Ref. 96, as exemplified by a rather thick, flat bezel. The model was basically developed with a center second sub-dial, but some earlier models had the specification of a small second sub-dial.
