Stay off the beaten track and go further with the lightest PRO TREK to date, the perfect companion for long walks and hikes.
The PRJ-B001 goes one step further with the first rotating protective bezel in the PRO TREK range. Rotate the bezel to switch between two different styles. When set to a sleek, angular design that complements your everyday outfits, the bezel covers the buttons, preventing accidental presses while walking or out on the town. Rotate the bezel 45 degrees to give it a more rounded look and reveal the buttons, allowing easy access to functions while hiking or training.
The watch features a soft urethane strap for comfortable wear even on long hikes.
In charcoal grey, which blends attractively with nature, and with fluorescent accents on the numerals and bezel, this watch is designed to complement any outdoor fashion style.
The main components of the case, strap and other elements are made from bio-based resin, a material that helps reduce environmental impact.
Beyond simple ease and style, this watch offers superior functionality, with Tough Solar charging and Bluetooth® for pairing with a smartphone. Press a button on the watch to record the date, time and position on a map within the app. It's a handy way to track your activity.
Remember awesome places you've been and note places you want to go back to. The lightest PRO TREK to date charts your path to new ways to enjoy the best of the outdoors.
