Calling all lovers of tough urban-cool outdoor gear!

Introducing the second PRO TREK collaboration with White Mountaineering®, the Tokyo fashion brand that celebrates the idea that “the field in which we wear clothes is all outdoors.” Sharing a commitment to bridging outdoor adventures and everyday life, the two brands come together to deliver a sophisticated fusion of design, utility, and technology.

Matte black design all about utility
We start with the White Mountaineering® brand matte black and bring in a design that places utility over flash. Indexes in phosphorescent white, hour and minute hands in white, and a seconds hand in red, all set against a matte black dial create a striking contrast that results in even better visibility and outstanding functional beauty. The iconic White Mountaineering® triangle pattern in translucent printing extends from the dial to the bezel for a sophisticated finish and a dynamic design that captivates from every angle.

New titanium band, lightweight comfort
The rugged case is complemented by an all-new H-link titanium band. Lightweight titanium delivers lasting comfort your wrist will love even on long outdoor adventures.

Advanced timekeeping system
Equipped with both radio-wave time calibration and Bluetooth®, the watch ensures precision timekeeping two ways. Multiband 6 tunes in with high-sensitivity reception to radio-wave time signals transmitted from six stations around the world to keep you on track when trekking far from the Internet.

Long-lasting, worry-free operation
Tough Solar delivers charging you can rely on, even from a weak indoor light source, to get you through long outdoor treks with ease.

True outdoor functionality and safety
The triple sensor keeps you updated with direction, barometric pressure, altitude, and temperature readings. With Location Indicator to check the direction of your destination and Time & Place to keep a record of your activity, your outdoor experiences are that much easier. The fully automatic, double high-brightness LED ensures visibility, even in dark places, and the flame-resistant bio-based resin case frees you from worry around campfires. A watch to help keep you safe, and a great match for how much you care for the natural world.

PRO TREK PRW-B1000WM

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.

Matte black design harmonizes with the triangle pattern

The timepiece takes a cool, functional approach to color, built around matte black — the signature shade of White Mountaineering®. White and red accent colors on the hands and 9 o’clock inset dial enhance visibility. The brand’s original triangle pattern graces both the dial with translucent printing and the stainless steel bezel with ion plating (IP), creating a refined look that changes with the viewing angle.

Solid titanium bracelet balances rugged design with lightweight comfort

Echoing the case design, the sharp-edged H-link titanium bracelet is finished with matte black IP. Titanium’s natural advantages — lighter weight than stainless steel and reduced risk of metal skin sensitivities — keep the watch comfortable even during long wear or when sweating. The clasp uses a secure double-lock, three-fold design.

Special features commemorate a special collaboration

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

Triple Sensor

Measuring compass bearing, altitude/barometric pressure, and temperature, Triple Sensor enables quick access to the accurate environmental data essential for mountain climbing and trekking.

Solar-powered timekeeping with radio control and Bluetooth® connectivity

The watch supports automatic time adjustment via radio signals and Bluetooth®. The solar-charging system reliably powers all functions.

Smartphone Link (app connectivity)

Connecting to a dedicated app enhances outdoor activities with features like Location Indicator for checking the direction to a destination and Time & Place for recording activity logs.

* In China, users are unable to manually set a point in the app.
