Light Powered 4000 series watches from Orient work with battery power from various light sources, which is charged in the solar cell underneath the dial. As a result, these watches require no battery replacement―something that is needed every three to five years with ordinary watches.
The solar cells operate continuously for over 4,000 hours (six months) after six hours of charging, not only from sunlight but also from light such as ordinary room illumination.
Incorporating the latest environmentally-friendly precision technologies, Light Powered 4000 series watches are ready to write a new page of history for Orient products.
