Description

Night-Sensitive Design for Enhanced Safety Introducing the PRO TREK Hiker Line's lightest model*, the PRJ-B001, in an all-black design with yellow accents. Of particular note is the dot-shaped reflectors on the bungee cord. These enhance safety during nighttime activities and ensure visibility in the dark. They also help prevent you from leaving your watch behind while outdoors.

Innovative 2-Way Design The unique Rotary Guard bezel allows you to choose between two styles depending on your needs. The square style is ideal for everyday use, hiding the buttons to prevent accidental presses. When you're active, simply rotate the bezel 45 degrees to reveal the buttons for improved operability.

Superior Comfort and Environmental Consciousness Inspired by outdoor gear, the bungee cord band, combined with the cross band, improves breathability and fit. The loop-type elastic cord and hook make it easy to wear even on bare skin or over clothing. The case and other key components are made from environmentally friendly biomass plastic.

Reliable Power Supply for Long Outdoor Trips The Tough Solar battery charges with minimal light, so you don't have to worry about running out of battery even during long trekking trips. Bluetooth® connectivity allows you to record your current location and time on a map in the dedicated app by simply pressing the watch buttons. You can also record scenic spots and places you want to revisit as an activity log, enriching your outdoor experiences. Combining lightweight functionality that's ideal for long trails and ultralight hikes, it's a reliable partner that will safely support your outdoor life, day or night. *As of August 2025
