Enjoy Japanese Unique Features in PRW-61!
First Casio watch to use biomass plastics.
For the first time in a PRO TREK or any Casio watch, the case and band are made from eco-friendly biomass plastics instead of conventional resins. The use of biomass plastics also delivers uncompromising resistance to hard use as well as comfort on the wrist. We are proud of this new material application for our line of premiere outdoor tools, PRO TREK.
Case back made from biomass engineered plastics.
For optimal wear resistance and an airtight seal, the case back is made from high-strength engineered plastics made from biomass materials. The case back has a wider flat surface, as well, for better torsional resistance.
High-contrast dial.
Dial contrast has been enhanced by using vivid white for the large bar indexes and hour and the minute hands, delivering optimum visibility in the field. The stainless steel bezel is engraved with city codes for an outdoor gear look.
Compact design never impedes movement. The smaller design never impedes wrist movement in the outdoors, while delivering uncompromising dial visibility and ease of use.
Triple sensor (digital compass, barometer/altimeter, and thermometer) senses natural changes.
Multi Band 6 radio-controlled solar watch for accurate time keeping
Super Illuminator
(high-brightness full-auto double LED light)
for readability in the dark

The most distinctive specs of PRW-61
*Editorial
— Biomass plastics in the case, band, and case back (the environmentally friendly biomass plastics are produced using materials derived from castor seeds and corn, as well as other raw materials)
— Solar Powered (Tough Solar provides constant behind-the-scenes power)
— Radio-controlled Watch; Multi band 6 (additional way for time sync. This watch receives time calibration radio signals that keep the displayed time accurate)
— Thermometer (can measure and display the outside temperature in a range from -10 C to 60 C)
— Barometer (measures the air pressures and displays tendencies in the weather)
— Altimeter (The electronic mechanism “estimates” the altitude based on the air pressure)
— Digital compass (measures and displays direction as one of 16 points)

Enjoy our PROTREK PRW-61 Watch Review
Let’s not forget, we are dealing with a new material that has its own special density, strength, and durability characteristics. During one interview, the guys from CASIO pointed out that it was the back cover that had the most problems in terms of maintaining water resistance [sorry, I lost the original source]. As a reminder, the new PRW-61Y-3 got 100m water resistance, as did all PROTREKs, which means the problem was solved. I would also like to mention a very pleasant tactile feeling while wearing the PRW-61Y-3 on the wrist. The feeling of softness and warmth never leaves). Read Full Review →

Official Casio Description. PRO TREK is a brand that feels nature, enjoys nature, and loves nature.
The case, band, and back cover are made of plant-based renewable material “biomass plastic,” giving consideration to the natural environment.
The material of the case and band has been replaced with environmentally friendly “biomass plastic” from the conventional resin. PRO TREK is, of course, the first attempt as a Casio watch. Quality such as robustness that can withstand hard use and wearability that is familiar to the arm keeps the standard so far. As an outdoor tool, we reviewed how to face nature from the material.

You ask, we answer…
CASIO’s original solar-charging system converts not only sunlight but also light from fluorescent lamps and other sources into power.
It’s the electronic mechanism that “estimates” the altitude based on the air pressure.
It measures and displays direction as one of 16 points.
It measures the air pressures and displays tendencies in the weather.
