The case and urethane band are crafted from biomass plastics made with castor oil and the band from biomass plastics made with corn. The duplex LCD lays out separate layers for the compass graphics and the clock functions, enabling a larger compass display for better legibility and easier navigation in a design that is both functional and beautiful. The rotating bezel makes it simple to record compass readings, and the Tough Solar charging system keeps the advanced functionality on the go. Get out and explore with a gentler footprint! * Biomass plastics are polymers produced using chemical or biological synthesis of materials sourced from plant matter or other renewable organic substances and are widely thought to help reduce environmental impact and promote the shift to a circular economy.
