Take flight with Citizen Promaster Sky, a collection of pilot watches engineered for precision and professional use. Aviation-inspired dials deliver clear legibility, while options include slide-rule bezels for in-flight calculations, world time, perpetual calendars and chronograph functions. Selected models, such as the Skyhawk, feature radio-controlled timekeeping that syncs automatically to atomic time signals. Powered by Eco-Drive and with many models water resistant to 200 metres, these aviator watches are built for exploring the world from above.
