Casio PRO TREK × White Mountaineering Black Bluetooth Sport Watch PRJ-B001WM-1

White Mountaineering® Collaboration Model: Elegant All-Black Design

We are excited to introduce the PRO TREK collaboration with White Mountaineering®, a Tokyo-based fashion brand known for creating clothing that emphasizes design, utility, and technology over market trends. Their philosophy, “the field in which we wear clothes encompasses all of the outdoors,” aligns perfectly with PRO TREK's mission to explore new frontiers in outdoor gear.

The PRJ-B001 timepiece is a testament to this partnership, featuring a solid all-black design that seamlessly integrates the White Mountaineering® triangle pattern, along with the logos of both brands. With meticulous attention to detail, this watch embodies a vision of simplicity and style, capturing the essence of both the great outdoors and everyday life.

Brand worldview expressed in color & design

This timepiece adopts the all-black color scheme inspired by the White Mountaineering® brand image and incorporates the clothing house’s original triangle pattern across the entire dial. An all-new design was employed to create a watch hand shape suitable to the White Mountaineering® style. These details come together to project a sharp look. Centered across the top of the watch face are the White Mountaineering® and PRO TREK logos.

Fire-retardant cloth band made from bio-based materials

The cloth band is made with bio-based materials produced using castor oil plants. In addition to the expected reduction in environmental impact, these plant-derived raw materials also provide excellent abrasion resistance, chemical resistance, and flexibility at low temperatures. The surface of the band is treated with flame retardant to hold up even when hit by sparks from cooking or campfires, resisting burn marks.

Special features to commemorate a special collaboration

The PRO TREK and White Mountaineering® logos are engraved on the case back. The watch comes in environmentally responsible packaging made with recycled materials to help preserve the environment.

Rotary guard bezel lets you switch things up

Turn the rotating bezel to switch between two distinct styles. The button-covering position prevents accidental button presses while out walking or in town. A 45-degree turn of the bezel ensures easy button access.

Time & place function gives you more ways to enjoy the outdoors

Pressing a button on the watch records the current time and position on a map within the dedicated smartphone app, making it useful as an activity log. Find new ways to appreciate the outdoors by reminiscing about breathtaking scenic spots and taking note of places to revisit.

Key resin components used in the case, case back, and more are made with bio-based resin. Produced using renewable organic resources, this material is expected to help reduce environmental impact.
