For their latest Pro Trek watch, Casio partnered with outdoor and climbing apparel, footwear, and backpack maker Mammut.

The Casio x Mammut Pro Trek PRW61MA-1A features Mammut’s signature orange on the analog hour, minute, and second hands, as well as on the top of the triple-sensor indicator, around the two right pushers. The official Mammut logo is on the right side of the dial, and the company’s elephant emblem is on the lower half of the cloth strap, both in the matching orange hue.

In addition to the non-tapered cloth strap, which has a monochromatic Mammut Alpine print with views of snowy mountains, there’s also a tapered black rubber strap. And like the case and caseback, both straps are made from eco-friendly materials. Specifically, the cloth band is made of recycled PET material from plastic bottles and other plastics, while the soft urethane band is made from biomass plastics using raw materials from castor seeds and corn. The case and case back are also made of biomass plastics.

This special Pro Trek is powered by solar power, which can use sunlight and some artificial light to recharge the battery, which like the manufacturing, is eco-friendly because the battery rarely needs to be replaced.

The marquee technical features of Casio x Mammut Pro Trek PRW61MA-1A are the compass, altimeter/barometer, and thermometer, which use Casio’s Triple Sensor Technology and provide crucial calculations for climbing and hiking terrain that has dangerous and continuously changing weather conditions.
