Solar power is a viable and environmentally friendly source of energy. Originally developed in the 1980’s, solar power relies on reflective lenses or mirrors to track sunlight into beams of light and convert these beams into electrical currents. It is estimated that by 2050, sixteen percent of the worldwide energy consumption will be solar powered.

Citizen Eco-Drive Silhouette

Interestingly the solar power concept was originally conceived in the late 1970’s with the introduction of calculators from Casio and Texas Instruments and select timepieces featuring solar panels. The solar watch was developed and conceptualized by Seiko, Citizen and popular Japanese watchmakers at the time.

In 1978, Seiko introduced the one of the very first solar-powered watches with their LCD Solar Alarm Chronograph. Solar watches were not widely received at the time due in part to glitches in the solar movements and cumbersome designs.

Citizen Eco-Drive Axiom

Almost two decades later in 1995, Citizen perfected the solar powered watch with the introduction of the Eco-Drive collection. Powered by the sun or any other light source, the Eco-Drive featured a rechargeable lithium quartz battery which never had to be replaced.

Unlike previous solar powered watches, the Eco-Drive drew power from both sunlight and interior light sources. The rechargeable lithium battery proved to be another advantage.

Citizen, Seiko and Sector are among the leading solar watch brands in the world today and you’ll find many of these brand’s top solar styles at during our Solar Time: Experience The Movement Of The Sun event.
