Get off the beaten path and go further, with the lightest PRO TREK¹ ever, the perfect companion for long trails and ultralight excursions.
The PRJ-B001 raises the bar with the first rotating bezel in the PRO TREK line. Rotate the rotating bezel to switch between styles. When set to feature a sleek angular design that fits in with everyday fashion, the bezel covers the buttons, preventing accidental button presses while walking or around town. Rotate the bezel 45 degrees so that it is rounded and reveals the buttons for easy access to features while hiking or exercising.
The watch features a soft urethane strap for stress-free wearing even on long excursions.
In anthracite gray or cream colors, which coordinate perfectly with nature, with touches of fluorescent colors in the numerals and bezel, this watch is designed to match outdoor outfits.
The main resin components used for the case, strap and other parts are made from bio-based resin, a material designed to help reduce environmental impact.
In addition to simplicity and style, this watch offers superior functionality, thanks to Tough Solar charging and Bluetooth® technology for pairing with a smartphone. By pressing a button on the watch, the app can log the date, time, and current location on a map, a useful way to record activity.
Remind yourself of the breathtaking places you have been and take note of the places you want to return to. The lighter PRO TREK points the way to new ways to appreciate the great outdoors.
