Many of the early photo voltaic watches in the 1970s had ground breaking and one of a kind models to support the array of photo voltaic cells necessary to electric power them (Synchronar, Nepro, Sicura, plus some designs by Cristalonic, Alba, Seiko, and Citizen). As being the many years progressed as well as performance with the solar cells elevated whilst the power requirements in the motion and Display screen lessened, photo voltaic watches began to be designed to appear to be other typical watches.[66]
