But we met the challenge by creating our own titanium-processing technology, and following that up with our proprietary surface hardening technology, Duratect.

Then, in 1995, we added a secondary lithium-ion cell for power storage, resulting in a light-powered analogue watch that runs for six months or more on a full charge.ĬITIZEN wanted to explore titanium’s infinite possibilities as a material for watchmaking. The development of thinner solar cells that could utilise room lighting, as well as sunlight, and more resilient electric double-layer capacitors inspired our engineers to continue improving light-powered watches. The increasing demands for secondary batteries and the growth of light-powered products among many industries during the 1980s drove CITIZEN's engineers to advance our technologies and pursue further improvements in light-powered watches.Īfter strenuous development efforts, we introduced the world's first industrial watch that could run up to 200 hours on a full battery charge. The product life was shorter than that of battery-powered watches, which continue ticking away regardless of the time of day. When the Crystron Solar Cell was brought into the market, solar cells and secondary batteries to store the surplus energy they generated were limited in terms of generation capacity.
