Get off the beaten path and begin your exploration with the lightest¹ PRO TREK ever, the perfect companion for long trails and ultralight hikes.
The PRJ-B001 raises the standard with the first rotating bezel in the PRO TREK line. Simply 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.
For this watch, we developed a completely new strap style: the outdoor gear-inspired bungee cord fabric strap. The combination of a fabric strap and elastic cord ensures a more breathable and comfortable fit. The elastic cord with loop can be attached to the hook to be worn over heavy clothing as easily as worn on a bare wrist.
In the powder blue color, which blends perfectly with nature, with touches of fluorescent colors in the numerals and bezel, this watch is designed to match outdoor outfits.
The main components, used for the case, strap and other parts are made with 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 to pair it 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.
