PRC 100 Solar 39mm | Model | Tissot® United States T1514222203100

New PRC 100 Solar styles are here. Shop now The PRC 100 Solar collection features Tissot’s Lightmaster Solar technology, based on photovoltaic cells discreetly integrated beneath the sapphire crystal. These nearly invisible, honeycomb-structured solar cells convert light into energy to power the quartz movement. Surplus energy is stored in a rechargeable accumulator, enabling up to 14 months of operation in complete darkness*. *Non-contractual image Ensuring visibility under all conditions is an important goal for Tissot. This is why some timepieces feature a material we call SuperLuminova®. This material is placed on visible parts such as dials and hands, where it functions as a miniature accumulator of reflected light when the watch finds itself in the dark*. *Non-contractual image
