PRW35LD-5D
Revel in the joy of being outdoors under the starry skies with a PRO TREK as committed to the environment as you are. Introducing the PRW-35LD with case, band, and case back made with bio-based resin, for an even more environmentally responsible design.
Featuring the first phosphorescent LCD in a Casio watch, this PRO TREK is the ideal companion for nighttime outdoor activities. Luminous material beneath the digital display emits a soft glow that enhances visibility so you can quickly check the time in the dark. Just 1 minute of exposure to a 200-lumen mountaineering headlamp from 5 cm away can provide enough power to illuminate the display for up to 1 hour.
In terms of style, too, the soft urethane band is tough and flexible, designed in a dark coyote brown that says outdoor gear all the way.
Packed with functionality, this timepiece is equipped with Triple Sensor to deliver compass bearing, barometric pressure, temperature, and altitude readings. Other handy features include Multiband 6, Tough Solar, and more, for the advanced and practicality you need to be prepared for camping or hiking in the dark.
