A solar-powered dive watch offers convenience and peace of mind over mechanical and battery-powered dive watches. Unlike a mechanical watch, a solar-charged watch will still run for many months if not worn at all. Unlike a battery-powered watch, a solar watch does not need costly and time-consuming maintenance every few years.<\/p>\n

Solar-powered watches use solar cell panels in the watch dial to convert light into energy. This energy is then stored in a rechargeable battery or capacitor to power the watch. Solar-powered watches can be charged from any type of light source, from indoor fluorescent lighting to the sun. <\/p>\n

Three companies dominate the solar watch market: Casio, Citizen, and Seiko. Casio uses the “Tough Solar” feature in many of its watches including its G-Shock<\/a> and Pro Trek brands. Citizen uses its solar “Eco-Drive” technology in hundreds of models. Seiko simply labels its many solar watches as “Solar.”<\/p>\n

Despite the large number of solar watches on the market, there are only a few solar-powered dive watches. True diving watches should be compliant with the ISO 6425<\/a> standard and are suitable for scuba diving. In order to qualify as one of the best solar-powered dive watches, all watches on this list must have an ISO-certified water-resistance rating of 200-meters (or 20ATM)<\/strong>. The ISO-certification is commonly indicated on the dial with a “Diver’s” label before the water-resistance rating (e.g. “Diver’s 200M”).<\/p>\n
