PRO TREK PRJ-B001 SERIES – Model PRJB001EX-1

Overview

Calling all lovers of nature. This PRO TREK delivers a seamless combination of practicality and portability, helping you maximize your enjoyment of the great outdoors.

The PRJ-B001EX design pinpoints the habits of dedicated campers with a band that doubles as storage. Use the band’s compartments to carry keys, or the cash you need to buy firewood or grab produce at a farmer’s market — everything you need right at your wrist.

More than a storage compartment, the reversible band also serves as protective coverage, and is designed to accommodate a carabiner attachment so the watch can hang from a backpack or inside a tent.

The rotary guard bezel turns to cover the buttons and prevent accidental presses during everyday use, then rotates back for easy access when your activity calls for it.

Key resin components are made of bio-based resin. Tough Solar charging keeps functions running on extended journeys, and Bluetooth pairing adds the Time & Place function to record when and where you go.
