The Ref. 5524 Calatrava Pilot Travel Time with a second time zone and a local-time date was launched in 2015 with a white-gold case and a blue dial. Now, it comes in a new rose-gold version with a brown dial and a black gradation. It is a refined and bold debut for an inimitable timepiece that pays tribute to Patek Philippe’s traditional aviator's watches.
