Casio PROTREK PRJ-B001-1DR

Casio PRO TREK

PRJ-B001-1DR

Get off the beaten path and go beyond, with the lightest* PRO TREK yet, the perfect companion for long trails and ultralight hikes.

The PRJ-B001 takes it up a notch with the first rotary guard bezel in the PRO TREK line. Turn the rotating bezel to switch between two distinct styles. When set to present a stylish angular design that complements everyday fashion, the bezel covers the buttons, preventing accidental pressing of buttons while out walking or in town. Turn the bezel 45 degrees to the rounder look and uncover the buttons for easy access to functionality while out hiking or training.

The watch features a soft urethane band for stress-free wear even over long stretches of hiking.

In charcoal gray or off white to coordinate beautifully with nature, with touches of fluorescent color in the numbers and bezel, this timepiece is designed to complement outdoor fashions.

Key resin components used in the case, band, and other parts are made with bio-based resin, a material expected to help reduce environmental impact.

Far beyond just ease and style, this watch offers superior functionality, too, with Tough Solar charging and Bluetooth® to pair with a smartphone. Press a button on the watch to record date, time, and position on a map within the app, a useful way to log your activity.
