PRO TREK

A 20-bar water-resistant line that extends its scope of use to mountains, rivers, and the sea, and is designed not only for mountaineering but also for activities such as fishing, rafting, and kayaking. It features the triple sensor at the core of PRO TREK while emphasizing practicality around water. Whereas CLIMBER LINE offers a more mountain-focused, full-fledged proposition, this line is intended for use across a broader range of outdoor settings.

The top-tier line in the PRO TREK lineup. Named after Manaslu, one of the world’s 14 peaks above 8,000 meters, it brings together enhanced specifications, construction, and finishing suited to extreme environments. Manufactured on Yamagata Casio’s dedicated high-end production line, it most strongly demonstrates the brand’s technical capabilities and craftsmanship compared with the current CLIMBER LINE, MULTI FIELD LINE, and HIKER LINE.

A series of smart outdoor watches derived from PRO TREK, introduced in official materials as the second Smart Outdoor Watch series. Low-power GPS and offline maps made it possible to check the user's current location. The series was offered in the WSD-F20, F21HR, and F30 models, all of which have since been discontinued. Distinct from CLIMBER LINE and HIKER LINE, it served a role centered on maps and connectivity features.

A line within PRO TREK designed for long-distance trails and hiking, with an emphasis on lightness. It brings its functions, size, and design together in a “just right” direction, making it easy to incorporate into everyday life through simple forms and earth tones. Smartphone connectivity also supports travel logs, offering a lighter entry point than the CLIMBER LINE.

A line that plays a central role in PRO TREK’s current lineup. It combines outdoor features, including the Triple Sensor, with designs focused on wearability, operability, and legibility, while offering a wide range of display styles and sizes. It has a distinct role from top-tier lines such as MANASLU, while offering more comprehensive serious outdoor features than the HIKER LINE.
