Seiko Watch Corp will release the "Hybrid" series of solar-powered wrist watches May 14, 2010, in Japan.

In the past, the company concealed photovoltaic (PV) cells by stacking colored resin plates. But, this time, it used transparent plates so that PV cells can be seen.

Seiko Watch employed such a design to attract interest from young people in their twenties, who reportedly have high concern about ecological issues. The name Hybrid means the union of ecology and design, and the company designed the panel and dial parts so that they fit with the design of the PV cell.

Seiko Watch will launch 10 types of wrist watches whose prices range from ¥19,950 to 26,250 (approx US$215-283). When fully charged, they operate for about six months.
