This outstanding Patek Philippe Calatrava Ref. 1509 is presented in beautiful overall condition. The case retains sharp hallmarks, including the Portuguese import marks, confirming that the watch was originally imported into Portugal. The dial remains unrestored and wonderfully preserved, featuring a highly desirable pink-on-pink configuration that is both rare and exceptionally attractive. An Extract from the Archives confirms production of the watch in 1943. A remarkable example of one of Patek Philippe's most elegant vintage Calatravas.
