The Ref. 5524 Pilot Travel Time enriches Patek Philippe’s venerable Calatrava collection with a large-format, decidedly masculine model that evokes images of the classic aviators’ timepiece, while details such as the blue dial, white-gold case and time-zone function place it in a category of its own.
