CASIO PRO TREK PRJ-B001B-1JF Hiker Line Solar Bluetooth Watch

The PRO TREK PRJ-B001B-1JF from the Hiker Line is a lightweight outdoor watch designed for hiking and everyday use. This model features a full black body with subtle yellow accents, enhancing visibility while maintaining a clean and practical design. Reflective dots integrated into the bungee cord band improve visibility in low-light conditions, helping with nighttime safety and reducing the risk of misplacement outdoors.

A unique rotary guard bezel allows two wearing styles. In daily use, the square-style layout covers the buttons to prevent accidental operation. During activities, rotating the bezel by 45 degrees exposes the buttons for easier operation. The breathable bungee cord and cross-band structure provide a secure and comfortable fit, suitable for wearing directly on the wrist or over outdoor clothing.

The watch is powered by Tough Solar technology, allowing it to charge with light and operate reliably during long outdoor activities. Bluetooth connectivity enables mobile link functionality, allowing time and location logs to be recorded via a compatible smartphone app. Major components such as the case are made with biomass plastic, reflecting an environmentally conscious material choice. Combining durability, lightweight construction, and practical functions, this watch is designed to support outdoor activities day and night.
