Offering a solar powered operation with Bluetooth for user-friendly access, the GA-B2100CT-5A arrives from G-Shock in a tan and brown colorway. Built from renewable materials, the octagon-shaped wristwatch features a bio-based resin body, and an organic cotton band that's been dyed using coneflowers (also known as echinacea). Boasting a shock-resistant construction that is operational up to 200m deep, the earth-conscious, earth-colored watch provides guilt-free, helpful technology at hand.
