Grateful Dead Light Wave。Lightly used, no visible scratches. Color is gray but looks like light blue. An ambitious, eco-friendly watch combines progressive design with solar charging and recycled ocean plastic construction, making the Light-Wave a clean, green, time-telling machine. Look closely at the translucent face and catch a glimpse of the solar panel within. Back out a bit and notice the head-turning dial details and the unique case and strap design. Then realize you\'ll never change another battery and know you\'re on a higher frequency.
