Casio Pro Trek × White Mountaineering PRJ-B001WM-1 – Limited Collaboration Model

Ready for the wild. Refined for the everyday. Built with purpose.

Introducing the Casio PRJ-B001WM-1, a bold evolution of the Pro Trek series in collaboration with Japan’s trailblazing fashion house, White Mountaineering. Designed with outdoor elegance and engineered for adventure, this exclusive timepiece merges high-performance features with environmentally conscious materials.

🏕️ Minimalist Design, Maximum Function

Featuring a stealthy matte black chassis accented by a sophisticated triangle motif and the discreet White Mountaineering logo, the PRJ-B001WM-1 speaks in visual whispers—but performs with thunderous capability. The rotary guard bezel allows seamless transition between modes: keep buttons hidden for urban sleekness or reveal them for rugged outdoor use.

🌍 Sustainable Craftsmanship

Built with flame-retardant bio-based resin, the band is more than just eco-friendly—it’s built for resilience and ready for the rigors of trail trekking and campfire cooking. Casio’s commitment to sustainability echoes throughout the design, aligning perfectly with White Mountaineering's philosophy of responsible innovation.

🚀 Performance-Driven Essentials

Packed with Tough Solar power for long-lasting reliability and 100M water resistance for versatile durability, this watch is made to adapt from cityscapes to summit climbs. Every feature—from the dual-mode bezel to the co-branded signature detailing—embodies the spirit of purposeful craftsmanship. The PRJ-B001WM-1 is a limited-edition release, blending advanced tech and rugged charm in one wearable package.

🧭 Purposeful Collaboration

This watch is more than gear—it’s a philosophy on your wrist. Whether you're navigating urban streets or unmarked trails, Casio and White Mountaineering deliver performance with style and conscience.
