Go bold and bright. Get out and explore the great outdoors!
In a first ever for a Casio timepiece, Neo-Brite phosphorescence is integrated into the solar dial design of the PRO TREK PRW-61LD to create a display that glows a soft green in the dark. Combined with blue luminescence on the index marks and hour, minute, and seconds hands, this PRO TREK delivers even greater visibility for the enhanced readability that your nighttime adventures require.
The case, band, and case back are made with bio-based resin, in keeping with the PRO TREK commitment to reducing environmental impact by using sustainable materials.
Delivering on outdoor utility, the model is equipped with Triple Sensor (digital compass, barometer/altimeter, and thermometer), as well as Multi-Band 6 radio wave reception from 6 transmission stations around the world, and Tough Solar to provide stable power for these functions and more. For optimum readability, the design features thick bar indexes to check time, direction, and other indicators at a glance, as well as slits on the band above and below the dial that serve as guides to quickly read the compass direction indicated by the second hand.
