Product Details
Description
The Casio Pro Trek PRJ-B001-1ER is the lightest PRO TREK Casio has ever built — a perfect outdoor companion for long hikes and demanding expeditions. The distinctive angular case made from bio-based resin combines sustainability with rugged functionality. The anthracite colourway with fluorescent accents on the numerals and bezel gives it a sporty look that works just as well in everyday life.
At the heart of the watch is the rotating protective bezel, introduced for the first time in the PRO TREK series: in city mode it covers the buttons to prevent accidental presses, while a 45-degree rotation unlocks all functions for outdoor use. Thanks to Tough Solar charging and Bluetooth connectivity via the CASIO WATCHES app, date, time and location can be captured on a map at the press of a button and activities can be logged. The soft strap made from bio-based urethane resin ensures comfortable wear even on long tours. The watch also features world time, stopwatch, countdown timer, 5 daily alarms, an automatic calendar until 2099, and water resistance to 10 bar.
