Triple Sensor (digital compass, barometer/altimeter, and thermometer) senses natural changes

Craftsmanship With Bio-Mass Plasstics

The case, case back, and soft urethane band are all made with a material known as biomass plastics. Using renewable organic resources such as castor oil plants and corn helps reduce the footprint. Eco-consciousness rendered in physical form, a fitting material for a real outdoor tool. *Biomass plastics are not used in the metal band of the PRG-340T.

Triple Sensor

PROTREK watches are equipped with the latest Triple Sensor, version 3 technology, making them even more accurate than before. Three highly sensitive, extremely small sensors measure with absolute precision and instantly display changes in your environment. The precision of the digital compass, altimeter, barometer and thermometer is only possible with the Triple Sensor technology. At the same time, the three layer sensor is 95% smaller and consumes 90% less energy than before.

The three layer sensor

The three layer sensor is at the heart of the PRO TREK watch and consists of three mini sensors which precisely measure direction, height, air pressure and temperature. The watch uses this technology to measure and display the changing conditions around you.

Case and urethane band and resin back cover. Biomass Plastic is a polymer material that contains renewable organic resources derived from chemical or biological synthesis and is expected to reduce the environmental load in order to achieve a circulation society. This time, the case and back cover are made of castor oil and the band is biomass plastic based on corn material. The soft urethane band uses a target guide, making it easier to read the direction of the second hand, and has a functional and beautiful design that makes it easier to understand your direction. The dial also features a thick hand and easy-to-read bar indexes for increased visibility. The PRW-61Y is designed with IP on the bezel. As the original function of the watch, it also combines practical functions such as multi-band 6 which receives radio waves from 6 stations around the world and tough solar.

Awesome watch
I have an older Pro Trek but didn't wear it much because it was so big on my thin wrists. This one fits great and I like the look of it. It doesn't feel rugged like the G-shock but is sturdy enough for daily wear and I even work out with it on. The back light is amazing. I like using the compass which uses the second hand. When it's on sale, it's a great buy.

Reviewed in the United States on May 7, 2022
Seems like a great Pro Trek. The illumination on this model is amazing (for a Casio at least). The plastic case back makes for a lightweight watch; however, I’m unsure if this will compromise the integrity of the watch in the future. Time will tell.

The positive display is a big plus for legibility. Also I like the touch of yellow, which doesn’t seem to be featured too often on Pro Treks. The bright white indices with matching hour/minute hands on a dark watch face make this really easy to read.

Long as this watch holds up, it’s a win in my eyes.
