Introducing a new model with an earth color theme from PRO TREK, a brand of authentic outdoor gear aimed at nature lovers and designed for outdoor usability.
The PRW-35Y-3BJF features a green band and black bezel and case, giving it a stylish yet highly visible design.
Like the base model PRW-35, the case, band, and resin back cover are made from biomass plastic, which is expected to reduce the environmental impact, demonstrating consideration for the environment.
In terms of functionality, the triple sensor allows you to measure direction, air pressure/temperature, and altitude.
In addition, it also comes with practical features such as a radio-controlled clock and Tough Solar, making it highly functional and practical for use in a variety of situations.
In addition, the PRJ-B001-5JF and PRJ-B001B-5JF use different earth colors for the band, bezel, case, buttons, and back cover, making them easy to wear for everyday use.
Like the base model PRJ-B001, it is equipped with Tough Solar and Bluetooth® smartphone connectivity.
By operating the buttons on the watch, the current time and location can be recorded on a map in the dedicated app, allowing you to manage your activity log.
This allows you to look back on memories of scenic spots and keep a record of places you want to visit again, expanding the ways you can enjoy the outdoors.
The main resin parts, such as the case and band, are made from biomass plastic, which is expected to reduce the burden on the environment, making this a lightweight model that matches a light and comfortable outdoor style.
