7 Year Warranty Campaign PRO TREK Hiker Line Tough Solar (Solar Charging System) Bluetooth Tough Solar (Solar Charging System) Men's Watch PRJ-B001B-1DF Hiker Line Ana-Digi All Black ◆The lightest* model of PRO TREK Hiker Line PRJ-B001. Dot-shaped reflectors on the bungee cord ensure visibility in the dark. It also helps prevent items from being misplaced. The rotary guard bezel can be switched between two styles. The square style is suitable for everyday use, and the buttons are hidden to prevent accidental operation. During activities, rotating the bezel reveals buttons for improved operability. The bungee cord band has excellent breathability and a good fit on the arm, and the loop-type elastic cord and hook make it easy to wear on bare skin or through clothing. Furthermore, the main parts use environmentally friendly biomass plastic. The tough solar allows it to be used for long periods of time, and the Bluetooth® link function allows you to record your current location and time on the map of the dedicated app by operating the watch. You can leave an activity log to enrich your outdoor experience. *As of August 2025 PRJ-B001B-1JF
