Ascent speed warning function that alerts you when you ascend at a speed of 10m / min or higher Product introduction Supports professionals who are active in harsh environments -A collaboration model with "Antarctic Survey ROV&quot
appears from SHOCK

This model is Casio Computer Co., Ltd. and Tokyo Marine University / Goto as a navigation device for a small underwater unmanned spacecraft (ROV) used in the joint use research of the 59th Antarctic Area Observation Team in January 2018. Collaboration model that was realized based on joint research by Dr. Shinpei

The base model adopts "FROGMAN", a master of G with specs that diving professionals demand

Completed the coloring and design with the full cooperation of Tokyo University of Marine Science and Technology, which conducts surveys of lakes in Antarctica using ROV

The colors are ROV's red, black, orange and blue, which challenge the investigation in harsh environments, and the back cover, backlight, band, and special packages are designed with silhouettes of Antarctica.

Tokyo University of Marine Science and Technology develops and operates ROV that operates stably even in the special environment of Antarctica, and conducts surveys of Antarctic lakes with the National Institute of Polar Research

In order to perform observations in the polar regions, it is necessary to transport ROVs manually, and downsizing and weight reduction are major issues, and equipment for measuring depth and orientation was no exception.

Therefore, in order to reduce the weight as much as possible, FROGMAN, which is a lightweight and compact size watch, can measure the correct direction even in water where the posture is not stable, and boasts high waterproofness.

This is a special collaboration model created by joint research between ROV and G-SHOCK for Antarctic research that confronts extreme environments.

[What is a Remotely Operated Vehicle (ROV) for Antarctic research?] Tokyo University of Marine Science conducts observation projects in the Antarctic region with the National Institute of Polar Research as one of the marine education and research.

The 59th Antarctic Regional Observation Team conducted a three-dimensional mapping survey of moss bowfish (organisms mainly composed of algae, mosses, and cyanobacteria) living in the Antarctic lakes.

The small underwater vehicle used in this survey was required to be robust and thoroughly lightened in order to achieve stable operation in a special and extreme environment called the South Pole.

The development is being carried out by a research team led by Shinpei Goto, assistant professor at Tokyo University of Marine Science and Science, and supports ecosystem surveys in Antarctic lakes with many areas that have yet to be elucidated.

・ Operation sound ON / OFF switching function
・ LED backlight (with full auto light, super illuminator, afterglow function, afterglow time switching (1.5 sec / 3 sec))
・ Driving time without solar power generation from full charge: When using functions / approx. 7 months, when using power saving / approx. 23 months * When radio waves are not received, normal quartz accuracy (average month Operates with a difference of ±
15 seconds)

Brand introduction G-SHOCK has built a new concept of toughness on watches

It all started with a developer's passion for creating a watch that would not break even if dropped, and a reckless challenge that overturned the common sense of the time.

Over 200 prototypes have been repeated, and about two years have been spent, and the shock-resistant structure has been completed.

It is the birth of technology to play the core of toughness

Since then, G-SHOCK has continued to evolve endlessly

Structure, material, function

Pursuing further toughness in every aspect

Model Number: GWF-D1000ARR-1JR
