Casio Pro Trek Tough Solar Duplex LCD Bio-Based Black Resin Watch PRG340-1D PRG-340-1D PRG-340-1

Get out into the great outdoors with a solar-powered PRO TREK featuring eco-friendly materials that care for the environment.

The PRO TREK line of authentic outdoor gear for nature lovers introduces the PRG-340, a timepiece that incorporates environmentally friendly biomass plastics* while delivering the same comfortable fit for your wrist. 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.
