"PRO TREK", which pursues usability in the outdoors and is particular about functionality and operability, and the Nature Conservation Society of Japan*, which investigates, protects, and utilizes various natural environments from mountains all over Japan to the sea. The 5th collaboration model of
*(Nature Conservation Society of Japan, "By the power of nature, open tomorrow
”, we are an NGO that aims to create a society where people and nature live in harmony, where everyone from babies to the elderly can live in beautiful and rich nature and live with smiles.
From the mountains to the sea, we continue to research, protect, and utilize nature all over Japan.

[Environmental Consciousness Model] As part of sustainable social activities, this model aims to raise awareness of environmental protection by interweaving a watch case using materials derived from living organisms and a band made of recycled materials.

[Triple sensor] Azimuth, barometric pressure/altitude, temperature can be measured with one push
[Standard radio wave reception] A small antenna with high sensitivity to receive standard radio waves with time information, and multi-band 6 compatible with standard radio waves in Japan (2 stations), North America, the United Kingdom, Germany, and China.
[Other product specifications] Water resistance to 10 bar / Low temperature resistance (-10 ° C) / STN liquid crystal boasting high visibility / Tough solar / Automatic needle position correction function / Full auto double LED light This model focuses on "playback" With the rise of environmental awareness, review of product materials is spreading as an action starting from familiar things.
By interweaving a watch case using materials derived from living organisms and recycled materials into the band, we aim to raise awareness of environmental protection, and as part of sustainable social activities, it is a model to enjoy nature close to nature.
Eco-friendly biomass plastic is used for the case, urethane band, and resin back cover.
In addition, a replaceable cross band made of recycled PET material is included.
The camouflage pattern is based on the motif of Japan's "satoyama" and the creatures that live there, which the Nature Conservation Society of Japan values.
With the number of animals and plants in danger of extinction increasing, we want people to be interested in the nature of satoyama and its conservation activities.
Such thoughts are included
Biomass plastics are polymer materials obtained by chemically or biologically synthesizing substances derived from renewable organic resources as raw materials.
The back cover is engraved with a design based on the motif of the endangered hawk "Grey-faced buzzard" as a creature that symbolizes the nature of Satoyama.
On the dial, a neon illuminator lights up when the light shines in the dark, and the indexes emit green light reminiscent of fireflies.
It is highly practical, including a triple sensor that can measure direction, atmospheric pressure/altitude, and temperature with a single push, multiband 6 that supports standard radio waves from 6 stations around the world, and tough solar that stably drives various functions.
Supports various activities with fully automatic lights that automatically turn on just by tilting your arm in dark places
This is a collaboration model between the Nature Conservation Society of Japan, which aims to create a society in which people coexist with nature, and the professional outdoor watch PRO TREK, which continues to evolve as a gear for those who love nature.
・STN liquid crystal boasting high visibility ・Triple sensor capable of measuring direction, altitude, atmospheric pressure, and temperature ・Receives standard radio waves from 6 stations around the world (2 stations in Japan, China, USA, UK, Germany) and automatically adjusts the time Multi-band 6, Tough solar, Atmospheric pressure tendency display function, Atmospheric pressure tendency information alarm, Low temperature resistance specification (-10℃), Hand position automatic correction function, Hybrid mount structure to improve the durability of the movement, Altitude, atmospheric pressure, and temperature If the needle overlaps the liquid crystal during measurement, the needle retraction function automatically moves the needle from the digital display temporarily ・Full auto double LED light (Dial: neon illuminator, liquid crystal: LED light)
・Tough solar (solar charging system) *Driving time without solar power generation from full charge: about 6 months when using the function, about 25 months when using the power saving mode ・Water resistant to 10 bar ・Radio wave reception function : Automatic reception (up to 6 times/day) (Chinese radio waves up to 5 times/day)/manual reception, received radio wave: JJY, frequency: 40kHz/60kHz (Fukushima/Kyushu compatible model) received radio wave: WWVB, frequency: 60kHz reception radio wave: MSF/DCF77, frequency: 60kHz/77.5kHz reception radio wave: BPC, frequency: 68.5kHz
In addition, the time difference is set by the selected city
*When radio wave reception is not performed, it operates with normal quartz accuracy (average monthly difference ± 15 seconds)

・ Hand position automatic correction function
・ World time: 29 cities around the world (29 time zones, with daylight saving time setting function) + UTC (Coordinated Universal Time) time display, UTC direct call function, home time city replacement function
