This is the G-SHOCK MASTEROF G series "Rangeman" GPR-H1000, which is designed for use in harsh environments.

Equipped with a heart rate monitor and GPS function, this is a survival toughness watch that can handle extreme situations such as piles of debris and dirt.

In addition to a dirt-resistant mud resist structure that prevents the intrusion of fine dust and sand, it also features a high-definition, high-contrast, easy-to-read MI P liquid crystal display.

The screen can be customized to suit the situation, supporting activities in harsh environments.

The rectangular watch body is strongly protected by left and right metal parts, and has a built-in GPS antenna and six sensors, making it suitable for a variety of occasions including trekking.

The trekking function allows you to check your heart rate during your activities, allowing you to keep track of your own exercise status.

Also equipped with a tide graph that shows the ebb and flow of the tide.

The texture of the band surface makes it difficult to slip even with wet fingers due to sudden rain.

The case, bezel, and band are made of biomass plastic, which is expected to reduce environmental impact.

The back band parts that enhance the fit on the arm are engraved with Rangeman's traditional wildcat silhouette, expressing the world view unique to MASTER OF G.

Bluetooth® linkage with smartphones allows for automatic time adjustment, email and phone notifications, and various data transfers.

We have adopted two charging methods, USB charging and solar charging, in pursuit of practicality.

Supports functions such as GPS measurement, heart rate monitor, notifications, and smart functions such as step counting with USB charging.

Even when the amount of charge is low, the time display can be driven only by solar charging, supporting land missions.

G-SHOCK aims to be a professional gear that can stand up to harsh environments.
