Casio Pro Trek PRJ-B001B-2DR Tough Solar Bluetooth Outdoor Resin Band Watch

The Casio Pro Trek PRJ-B001B-2DR introduces a fresh direction for the Pro Trek collection, combining outdoor functionality with lightweight everyday comfort. Designed for hikers, travelers, and outdoor enthusiasts, this model stands out as one of the lightest watches in the Pro Trek lineup. Featuring a modern dusty blue case with vibrant orange accents and a rugged textile bungee-style strap, it delivers a unique trail-inspired aesthetic that blends adventure and urban styling. Casio designed the PRJ-B001 series as an ultra-light companion for long hikes and daily exploration.

One of its most distinctive features is the innovative rotary guard bezel. Rotate the bezel to switch between two configurations: one protects the side buttons from accidental presses, while the other provides quick access to functions during activity. This design improves usability during hiking and active outdoor use while adding a dynamic visual identity unique to the PRJ-B001 line.

Powered by Casio Tough Solar technology, the PRJ-B001B-2DR converts light into energy for reliable operation and minimal maintenance. Bluetooth connectivity through the CASIO WATCHES app enables automatic time adjustment, world time synchronization, activity logging, and a useful “Time & Place” feature that records location and moments from your adventures.

Watch enthusiasts frequently praise the series for its comfort and extremely lightweight feel. Community feedback describes it as surprisingly comfortable and easy to wear for long periods, with several users comparing it to a lighter, outdoor-focused alternative to popular G-Shock models.
