New Casio Pro Trek premium collab watch launches with titanium band, sapphire crystal, and Tough Solar
Casio and the Japanese fashion label White Mountaineering have finally confirmed the February 2026 launch of their second collab timepiece, the high-end Pro Trek PRW-B1000WM-1. Moving away from the resin builds used in some previous watches, this iteration is based on the relatively new PRW-B1000 chassis, using a solid titanium band and advanced technical sensors. The model is priced at approximately ¥140,800 (~$900) and features a matte black utility design with White Mountaineering’s signature triangular pattern etched into the ion-plated stainless steel bezel.
The PRW-B1000WM-1 is the first Pro Trek series to use Tough Solar power, Bluetooth smartphone connectivity, and Multiband 6 radio-controlled time adjustment and pack it all into a single unit. The watch is great for high-altitude environments, thanks to its a "Triple Sensor" suite that can measure altitude, barometric pressure, temperature, and compass bearing. A dedicated "Location Indicator" at the 9 o’clock sub-dial, which is modeled after a traditional climbing piton - works in tandem with the Casio Watches app to display direction and distance to saved waypoints.
Material-wise, the watch's highlight is its durability - it weighs 120 g with its H-link titanium bracelet. The center case is constructed from flame-retardant bio-based resin, and the dial is protected by a scratch-resistant sapphire crystal with an anti-reflective coating. It comes with a 100-meter water resistance rating and is specified for low-temperature operation down to –10°C.
