CASIO’s Pro Trek line is made for the outdoors—from rugged mountain trails to deep forest expeditions. Featuring Triple Sensor technology (altimeter, barometer, compass), Tough Solar charging, and in many models, Multiband 6 atomic timekeeping, Pro Trek watches are optimized for navigation, weather tracking, and survival awareness. Designed with large, legible displays and operated via direct-access buttons, these watches are tested in extreme environments. Newer models also incorporate bio-based resin materials for greater sustainability without compromising performance. Whether you’re climbing peaks or camping off-grid, Pro Trek is your wrist-bound toolkit for the wild.
