What was the first solar-powered wristwatch?

The Synchronar 2100, introduced in 1976, was the first solar-powered wristwatch. It was notable for its photovoltaic cells and sold for around $500 at the time of its debut. The “top” of the watch was dominated by windows to maximize light absorption.

When did solar watches come out?

Some of the early solar watches of the 1970s had innovative and unique designs to accommodate the array of photovoltaic solar cells needed to power them (Synchronar, Nepro, Sicura and some models by Cristalonic, Alba, Rhythm, Seiko and Citizen). In 1996, Citizen started to sell analog light-powered watches under the Eco-Drive name. [ 2]
