PRO TREK, now with eco-friendly bio-based resin

The PRO TREK brand stands for experiencing, enjoying, and preserving the wonders of nature. Now available in a new model that uses eco-friendly bio-based resin in the case, band, and case back.

Bio-based resin

Bio-based resin is polymers produced using chemical or biological synthesis of materials sourced from plant matter or other renewable organic substances. They are widely thought to help reduce environmental impact and promote the shift to a circular economy. PRO TREK employs bio-based resin that is made from materials extracted from castor seeds and corn.

First Casio watch
to use bio-based resin:
Delivering
uncompromising
durability and comfort

For the first time in a PRO TREK or any Casio watch, the case and band are made from eco-friendly bio-based resin instead of conventional resins. The use of bio-based resin 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
bio-based resin

For optimal wear resistance and an airtight seal, the case back is made from high-strength engineered resin made from bio-based 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.
