In 1970, Citizen took a risk and crafted the first watch case made entirely of titanium. 50 years later, the brand is celebrating that milestone with the release of the Satellite Wave GPS F950. The watch uses a material called Super Titanium, which is also being used in a lunar lander and rover in development by iSpace in Japan. The watch benefits from two-piece construction using a combo of two surface hardening technologies for rich coloration and top-notch scratch resistance. The multi-layered chronograph is designed to bring to mind the infinite reaches of space, and also includes Citizen's Eco-Drive technology that is solar powered to keep the watch running indoors or outdoors. Limited to just 550 total pieces.
