Casio is expanding its popular Pro Trek lineup with the new Pro Trek PRW-61D-2, a premium outdoor watch that blends rugged functionality with a dial design inspired by a striking natural event in Japan. Built on the established PRW-61 platform, this release keeps the tools Pro Trek fans expect, but adds a more story-driven look that’s meant to stand out beyond the usual utilitarian styling.
At its core, the Casio Pro Trek PRW-61D-2 is designed for the outdoors. It features Casio’s dependable Tough Solar charging system, Multi Band 6 radio-controlled timekeeping for accurate automatic time updates, and the brand’s Triple Sensor suite. That sensor package covers key backcountry and travel essentials, including an altimeter, barometer, digital compass, and thermometer. Alongside those headline features, the watch also includes everyday functions such as world time, a stopwatch, countdown timer, multiple alarms, and 100-meter water resistance.
What makes this model feel different is the execution. Casio draws inspiration from Japan’s seasonal “Dragon Eye” phenomenon found at Mount Hachimantai, where melting snow and ice create an eye-like formation. The PRW-61D-2 reflects that scene with a textured dial pattern that evokes thawing snow and ice, paired with a deep blue bezel meant to mirror the ring of water that forms around the “eye.” The end result is a Pro Trek that still looks like a serious tool watch, but with a more intentional, nature-inspired aesthetic.
Casio also steps up the materials on this version. The PRW-61D-2 uses a sapphire crystal with an anti-reflective coating, improving scratch resistance and helping visibility in bright conditions. It also includes a screw-down crown for better sealing. In a nod to sustainability-focused materials, the case and caseback are made from bio-based resin.
The strap is another notable upgrade. Instead of a standard resin band, Casio uses a carbon fiber-reinforced bio-based material, similar in concept to what’s been seen on certain higher-end Pro Trek models. The goal here is improved rigidity and long-term durability while keeping the watch comfortable for daily wear and outdoor use.
Visibility is clearly a priority as well. The dial, hands, and indices receive generous lume, and the backlight supports both the digital display and the analog elements. For hikers, campers, and anyone who checks the time before sunrise or after dark, this should translate to above-average nighttime readability for the segment.
As for pricing and availability, the Casio Pro Trek PRW-61D-2 is expected to come in at about $500 based on its Japanese price of ¥79,200. For now, it has been announced for Japan, with sales set to begin in May. A broader international release seems possible, but has not been confirmed yet.
