Scale even steeper heights with the PRO TREK PRW-B1000, built to take on some of the most extreme outdoor adventures. The square stainless-steel bezel, inspired by the iconic vertical rock formation of Yosemite’s El Capitan, calls you to take on similar challenges. The indicator hand of the inset dial at the 9 o’clock position evokes the old-school piton once used in rock climbing — honoring a spirit of adventure and respect for nature. This watch climbs far beyond ease and style. Tough Solar delivers charging you can rely on, even from a weak indoor light source, and you can count on radio-controlled calibration and LED lighting to get you through long treks and overnight trips. PRO TREK watches deliver triple sensor measurements to keep you updated with direction, barometric pressure, altitude, and temperature readings. This PRO TREK is the only one equipped with both Bluetooth and Multiband 6, two ways to ensure precision timekeeping. With Multiband 6, even when far away from the Internet, the PRW-B1000 tunes in to radio signals to calibrate the time in places as far flung as Japan (2 stations), China, North America, the UK, and Germany. The fully automatic double LED light illuminates both the analog and digital displays with just a tilt of the wrist — perfect for when your hands are full or visibility is low. Large buttons designed for easy operation even when wearing gloves are sure to make this timepiece a favorite. Sync with your smartphone via Bluetooth for automatic altitude correction, use the Location Indicator feature to check the direction of your destination, and count on the Time & Place to keep a record of your activity. Simply tap on the app to effortlessly manage alarms and timers. The watch is made with recyclable and environmentally considerate materials — the case with flame-resistant bio-based resin and the band with lightweight, high-strength cellulose nanofiber (CNF) — in keeping with your love of nature. Also with 100-meter water resistance, the PRO TREK PRW-B1000 is ready to take on anything from weekend camping to demanding mountain climbs.

Specifications
Solid design inspired by iconic Yosemite rock face
Yosemite’s iconic rock formation is the very image of the steep rock faces that climbers revere. Its form is echoed in the sharp edges, multifaceted form, and corner slits, representing cracks in the rock face, of the stainless-steel bezel. Large metal components for the side buttons and crown give the timepiece a solid look and feel. The multilayered dial structure emphasizes a sense of depth, while large watch hands and raised indexes deliver enhanced readability. The indicator in the inset dial at the 9 o’clock position evokes the piton — a symbol of the evolution of climbing gear in the 1970s.


Dura Soft band (CNF-reinforced rubber) for wearable comfort as well as functional utility
This is the first Casio watch with a band reinforced with CNF, a functional bio-based material turning heads around the world. CNF kneaded into rubber resin creates a band that retains its lightweight flexibility, while adding the strength and durability to withstand environmental factors that adventurers need when heading outdoors. The band is designed with just the right thickness to ensure a great fit.
Cellulose nanofiber (CNF)
A bio-based material made from wood-derived fibers refined to the nanometer level. In addition to high tensile strength and the ability to withstand hydrolysis and low and high temperatures, this environmentally responsible material can be processed with either material or thermal recycling.
1: Hydrolysis resistance (crack resistant)
2: Low-temperature resistance (remains flexible down to –20ºC [–4ºF])
3: High tensile strength (more durable than silicone)
4: High-temperature resistance (stands up to heat better than conventional urethane bands)


Flame-retardant case for peace of mind by the fire
The center case is made from flame-retardant resin produced from bio-based resin. With this certified V-0 grade UL94 material, flames self-extinguish when the ignition source is removed, preventing them from continuing to burn. A safety precaution to free you from worry when sparks are flying from the cook stove or the campfire.
V-0 grade UL94 material
A standard for flame retardancy in plastic materials set by Underwriters Laboratories (UL), a U.S.-based product safety certification organization. The flame-retardant resin used for this watch meets the V-0 certification standards awarded to materials with self-extinguishing properties that stop burning when the ignition source is removed.


Location Indicator guides adventures out in the field
The watch is equipped with Location Indicator, a useful function for outdoor activities to help you locate where you are and where you’re headed. The indicator hand in the inset dial at the 3 o’clock position shows the direction of a point set on the app map,* and the LCD displays the distance from your current location. You can also save your current location on the map using the watch. This is useful for finding your way back when you descend a mountain or need to locate your parked car. Used in conjunction with the digital compass, which indicates north via the watch’s seconds hand, this feature delivers reliable guidance in any number of outdoor scenarios.
* In China, users are unable to manually set a point in the app.

Triple Sensor (digital compass, barometer/altimeter, and thermometer) senses natural changes

Attention to materials: Bio-based resin
Key resin components used in the case, case back, and more are made with bio-based resin, a material expected to help reduce environmental impact.

Tough Solar powered for converting light to energy
Generates ample power for smooth operation of various power-hungry functions, from sunlight or low indoor lighting. No charging equipment needed, enabling convenient and reliable use in outdoor environments.

Radio control and Smartphone Link enhance outdoor usability
With time calibration signals transmitted from six stations around the world and support via Bluetooth®, the watch automatically adjusts to guide your outdoor activities and keep you on precision time. Sync with the dedicated app for even more functions that deliver what you need in the great outdoors. Tap into the app to automatically adjust the altitude reading on the watch or track altitude and route traveled on the map within the app for even more convenient utility and fun outdoors.

Super Illuminator (high-brightness full-auto double LED light) for maintaining watch readability in the dark

Scratch-resistant, highly transparent sapphire crystal with an anti-reflective coating
