When we think of Gwen Stefani we think of her cutting-edge fashion and rock star style. So it’s no surprise that her new line of watches launching today—a collaboration between her line Harajuku Lovers and Q&Q SmileSolar—have a futuristic quality to them. The watches require no batteries and are 100% fueled by the sun—30 minutes of direct sunlight will give you 3 months of charge. On top of being eco-friendly, the playful designs were inspired by pop art and Japanese street style—making them the perfect hit of color for the upcoming string of music festivals.
