SOLAR POWER technology

For centuries, light has been used to measure time. In its collection of watches, SWISS MILITARY by Chrono implements modern SOLAR POWER technology in order to create an outstanding product. The interplay between tradition and innovation internalises ecological awareness whilst maintaining a high standard of reliability, precision and vibrancy.

Light as a source of power

SOLAR POWER technology uses natural or artificial light as operating power. The dial of the watch channels the light to the subjacent solar cell which collects and converts it into electricity. The latter activates the motor of the watch so that excess energy charges the integrated battery. Having been charged completely, the watch, therefore, has the capacity to run in the dark for several months (power reserve).


SOLAR POWER technology is a clean and ecological source of power. Conventional quartz watches run with the help of disposable batteries. SOLAR POWER technology makes battery replacements redundant as the watch runs reliably and with the highest precision through the impulse of the natural propulsion of light, which charges the integrated battery every time the watch is exposed to light.
