💪 Military-Grade Durability

Built to military standards, the T-Rex3 Ultra features a zinc alloy and plastic case that resists scratches, drops, extreme temperatures, high altitude, low air pressure, dust, salt spray, and liquid exposure. IP68 waterproof — wear it in the rain, while washing hands, or during intense workouts without worry.
