White Mountaineering® collaboration model: Solid style dressed in all black
Introducing a PRO TREK collaboration with White Mountaineering®, a Tokyo fashion brand that designs clothing based on three elements — design, utility, and technology — rather than market trends, under the concept that “the field in which we wear clothes encompasses all of the outdoors.” PRO TREK timepieces pioneer all-new terrain in outdoor gear, making for a natural pairing of two brands that explore the connections between the great outdoors and everyday life. The solid form of the PRJ-B001 is dressed in all black and subtly incorporates the White Mountaineering® triangle pattern, the two brands’ logos, and more. With meticulous attention to detail, the timepiece expresses a worldview of simplicity and style.
LINEUP
Bluetooth® / TOUGH SOLAR

The Japanese fashion brand White Mountaineering® debuted with its 2006 autumn-winter collection. The brand brings to life designer Aizawa Yosuke's concept of creating fashionable clothing with a focus on outdoor activities. Achieving this vision requires a whole new approach to manufacturing that focuses not only on design, but also on utility and technology. Bringing the three conceptual pillars of design, utility, and technology to fashions that do not submit to market trends, White Mountaineering® is a Tokyo brand that is highly appreciated for its incredible attention to materials and detail.
FEATURES
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.

Attention to materials: Bio-based resin
