PRJB001WM-1 | PRO TREK PRJ-B001 Series Black - Casio

Calling all lovers of tough urban-cool outdoor gear! Introducing a PRO TREK collaboration with White Mountaineering®. The Tokyo fashion brand’s principal concept is that “the field in which we wear clothes is all outdoors. One, design. Two, utility. Three, technology. The imagination to fuse these elements together. The attitude of not submitting to sales or market needs.” PRO TREK timepieces pioneer all-new terrain in outdoor gear, making the two brands natural partners for exploring the connections between the great outdoors and everyday city life. The solid PRJB001 form is dressed in all black with subtle White Mountaineering® details like the brand’s diamond pattern, as well as both brands’ logos and more. With meticulous attention to detail, the timepiece expresses a worldview of simplicity and style. The flame-retardant cloth band is made of bio-based materials produced using castor oil plants. These plant-derived raw materials are not only expected to reduce environmental impact, but also provide excellent abrasion resistance, chemical resistance, and flexibility at low temperatures. The surface of the band is treated with flame retardant to resist burn marks and free you from worry around sparks from cooking or campfires. More than just design fashion, this watch offers utility and technology, too, with Tough Solar charging and Bluetooth® to pair with a smartphone. Press a button on the watch to record date, time, and position on a map within the app, a useful way to log your activity. Reminisce about the breathtaking places you’ve been, and take note of places you want to go again. The lightest PRO TREK yet charts your course to all-new ways of appreciating the great outdoors in White Mountaineering® outdoors-inspired streetwear style. White Mountaineering® The Japanese fashion brand White Mountaineering® debuted with its 2006 autumn-winter collection. The brand brings to life designer Yosuke Aizawa’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.
