As Washingtonians celebrate the warm weather and everything spring has to offer, we are reminded of how paramount it is to preserve the environment. Luckily, several watch brands are on top of their solar game, unveiling pieces that run on the sun’s power and light.
Solar watches collect and store energy from any light source, and then convert it into electrical energy (generally stored in a rechargeable lithium-ion cell) that powers the watch. Once the solar watches are charged, the battery enables timekeeping for months on end. Depending on the maker, some can run for as long as six months before needing more light. Many solar watches offer a great number of functions, such as chronographs, dual-time indication, or Global Positioning Systems (GPS). As the world continues to embrace renewable energy sources and becomes more solar savvy, these watches are a natural choice that offers service, sustainability, and style.
