G-SHOCK/BABY-G has been creating collaborative models with various environmental organizations since the late 1990s and continues to support them.
In 2023, under the theme "Love The Sea And The Earth," we will continue to support EARTHWATCH, which supports a wide range of environmental conservation and research, including endangered ecosystems, marine and biological diversity, and climate change. I will go
The collaboration model uses MUDMAN from the Master of G series, and is designed with the motif of the Hiroobi Fiji iguana*, which is endangered due to deforestation etc.
The characteristic green and blue body colors of the Hiroobi Fiji iguana are boldly expressed with colored resin and all-over printing.
The stainless steel parts of the front buttons are coated with brown IP to resemble the eyes of an iguana.
EARTHWATCH's slogan "Change the World. Yourself." and the EARTHWATCH logo are printed on the band and ring.
This model features detailed designs throughout, such as the logo appearing on the LED backlight and the "Love The Sea And The Earth" symbol engraved on the back cover.
In addition, it uses biomass plastic as the material and is equipped with tough solar power that can be powered even by a small amount of light such as fluorescent lights.
The packaging uses a special box made of recycled paper.

*The altimeter is a relative altimeter that converts changes in atmospheric pressure into altitude.
If the atmospheric pressure changes due to weather conditions, the altitude of the measured value will also change.
*When measuring the outside temperature, remove the watch from your wrist to prevent it from being affected by body temperature, sweat (water droplets), direct sunlight, etc.
