Casio Pro Trek PRW3510 Adventure Watch With unlimited battery life, high levels of durability, and a capable tri-sensor array, Casio's newest timepiece just may be your ideal adventure companion.


Granted, the Casio Pro Trek PRW33510 doesn’t come with the plethora of features that make modern adventure watches from Suunto and Garmin a whole lot more useful in the wild. However, it also doesn’t run on a rechargeable battery that’s likely to run out of juice before your actual adventure is done.  For an extended stay out in the mountains, we have a feeling you’ll appreciate what that brings to the table a whole lot more.

Using Casio’s Tough Solar tech, the watch runs strictly on solar power, so as long as you don’t end up trapped in a cave for seven months (the onboard battery holds that much charge), it should keep on functioning without missing a single beat. No need to conserve your power or replenish from a power bank – it just keeps running and doing its job, day in and day out.

The Casio Pro Trek PRW3510 uses a super twisted nematic (STN) LCD, which boasts better visibility in both high- and low-light environments, all while using up less energy than traditional LCD panels. It also incorporates Casio’s Triple Sensor Version 3, a sensor array that’s 95 percent smaller than previous implementations, for providing altitude, barometric pressure, and direction readings. With that sensor on board, the watch can serve as a digital compass for figuring out your direction, an altimeter for helping estimate how long a climb will take, and a barometer for predicting weather patterns.

Features include 200 meters of water resistance, a stainless steel rotary bezel with direction markings, and LED backlighting. It also comes with multi-band atomic timekeeping that updates six times a day to ensure you have the correct time, regardless of time zone.

Available now, the Casio Pro Trek PRW3510 is priced at $320.
