The new Eco-Drive SATELLITE WAVE – AIR features higher performance with more advanced satellite timekeeping system that delivers much higher reception sensitivity as well as provocative aerodynamic design. This is the world's first light-powered watch with a full-metal case made of CITIZEN’s proprietary titanium material, which receives time signals from navigation satellites. Its speed to correct the time is also the fastest among all satellite-synchronized watches. As part of the newly defined PROMASTER collection, it embodies the spirit of challenge and of exploring the unknown.
