Like its base model, the PRJ-B001, this easy stylish timepiece is equipped with 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 dedicated smartphone app, for a useful way to log your journeys. Find new ways to appreciate the outdoors by reminiscing about breathtaking scenic spots and taking note of places to revisit.

Bio-based resin for key resin components in the case and more is not only expected to help reduce environmental impact, but makes for a lighter watch, as well.

Lightweight, compact, stylish, and practical — this timepiece is all about the great outdoors.

Rotary guard bezel lets you switch things up

Turn the rotating bezel to switch between two distinct styles. The button-covering position prevents accidental button presses while out walking or in town. A 45-degree turn of the bezel ensures easy button access, making outdoorsy functions like the light and Smartphone Link even more user friendly.

Comfort sizing and colours that coordinate

The lightest timepiece of the PRO TREK line fits Bluetooth® and Tough Solar into a compact case, with a sloping back for less interference with the back of the hand. It stays comfortable even when worn for long periods, and allows the wrist to move and bend smoothly. Charcoal gray, off-white, and dusty blue colour-ways harmonise with nature, while fluorescent accents add a sporty touch to outdoor functions.

Time & place function gives you more ways to enjoy the outdoors

Pressing a button on the watch records the current time and position on a map within the dedicated smartphone app via Bluetooth®, making it useful as an activity log. Find new ways to appreciate the outdoors by reminiscing about breathtaking scenic spots and taking note of places to revisit.

Inset dial with a carabiner motif

The indicator hand on the inset dial at the 9 o’clock position is modelled after a carabiner. Design and readability come together in its fluorescent accent colour.

Tough Solar and Bluetooth® for full functionality at your fingertips

Super Illuminator (high-brightness double LED light) for maintaining watch readability in the dark
