Introducing the PRW-6900BF, from the PRO TREK climber line, authentic outdoor gear for nature lovers, which uses eco-friendly materials and is finished with a rough outdoor style theme.
The PRW-6900BF has a design inspired by bonfires, which are popular in outdoor scenes such as camping.
Luminescent lights that emit red light in the dark, reminiscent of the red flames of a bonfire, are placed on the tips of the hour, minute and second hands, and on the indexes on the dial.
In addition, the surface of the metal bezel is forged with an uneven texture to create a rough texture reminiscent of a cast metal such as a Dutch oven that is exposed to fire.
The case, band, and resin back cover are made of biomass plastic resin, which is expected to reduce environmental impact, making environmental consideration a reality.
Equipped with triple sensors, it can measure direction, altitude/barometric pressure, and temperature.
In addition to the measurement function, the watch also has practical functions such as multi-band 6 that receives radio waves from 6 stations around the world and tough solar.
This model is packed with high functionality and practicality that can be used in a variety of situations, with a strong design typical of outdoor gear that matches scenes such as bushcraft.
