Citizen Attesa Satellite Wave GPS F950 (Super Titanium)

The CC4055-65E is a Japan-market Attesa that sets itself by satellite. Citizen's F950 Eco-Drive takes position and time from GPS satellites orbiting 20,000 km up, so it corrects itself to the right time zone and calendar anywhere in the world, and it runs on light, with no battery to change. It has world time, a perpetual calendar and Citizen's Double Direct Flight function for switching between home and local time, and the crystal carries Citizen's Clarity coating to cut glare. Case and bracelet are Super Titanium, which Citizen says is 40 percent lighter than steel and more than five times harder at the surface. At 44.6 mm across and 111 g on its bracelet it is a big watch, rated to 100 m. It sells in Japan for 330,000 yen.
