From PRO TREK, a line of authentic outdoor gear designed for nature lovers, comes the “PRG-340,” a solar-powered model that incorporates materials expected to help reduce environmental impact. It features a triple sensor (compass, barometric pressure/altitude, and temperature) useful for outdoor activities, as well as Tough Solar technology. Key components incorporate biomass materials; specifically, the PRG-340B3JF features a flame-retardant crossband made from “CASTLON,” a nylon material derived from 100% renewable organic resources. CASTLON is a nylon 11 made from castor oil and contributes to reducing environmental impact as a carbon-neutral material. Compared to conventional Nylon 6, it offers superior strength, lightness, abrasion resistance, chemical resistance, and flexibility at low temperatures. Like the base model PRG-340, it features an easy-to-read duplex LCD display. Visibility is enhanced by a two-layer LCD structure: the upper screen graphically displays the bearing, while the lower screen shows the time and measurement values in large characters. The adoption of a thinner LCD allows for high functionality while keeping the watch slim. The PRG-340, a solar-powered model made with materials expected to reduce environmental impact, is packed with high functionality and practicality to handle a wide range of outdoor scenarios.

When atmospheric pressure changes due to weather conditions, the measured altitude will also change. *When measuring the outside temperature, remove the watch from your wrist to prevent it from being affected by body heat, sweat (water droplets), or direct sunlight.
