As a medium version of the Calatrava Pilot Travel Time launched in 2015, the Reference 7234 combines a rose-gold case with a brown dial and a subtle black gradation toward the periphery. Along with its dashing aeronautical style, this model incorporates a second time zone display, notable for its ease of use, and a local-time date. It is also the first self-winding Travel Time model in Patek Philippe’s collection for women.
