The "MASTER OF G" series is a line of G-SHOCK watches developed for use by professionals working in extreme environments. This series is divided into three categories based on the area of activity: "Sea," "Air," and "Land." Among these, the models specifically designed for harsh land environments are commonly known as "Land G." This article introduces the features of Land G watches, which keep accurate time even in muddy, sandy, and dusty environments, and presents three recommended current models. We will explain the functionality of these tough watches, which pursue practicality as survival tools.
The strength of "RikuG," which specializes in demanding land-based activities.
A key technology representing the "G-Shock" series is its "Mud Resist" structure, which prevents mud, fine sand, and dust from entering the watch's interior. In mountainous areas, deserts, and places where rubble is piled up, fine particles can get into the gaps of the watch's buttons, causing malfunctions. The G-Shock series employs a unique structure to maintain reliable operation even in such harsh environments.
Each button's operating area is designed to easily drain muddy water and is protected by a cylindrical stainless steel part. Furthermore, a gasket is provided on the button shaft to physically block the entry of mud and dust. Some models also feature a case made of carbon material to increase rigidity and suppress deformation due to impacts, ensuring high airtightness for the entire watch.
This mud-resistant structure prevents damage to the interior even in situations where it is covered in mud and debris, and allows dirt to be removed by washing with water.
Furthermore, the lineage of G-Shock watches can be broadly divided into the "Mudman," which primarily features a digital display, and the heavily armed "Mudmaster," which combines a digital display with a digital display. In particular, many Mudmaster models are designed for use with heavy machinery such as heavy equipment and drills, and feature a "vibration-resistant structure" in which the internal module of the watch is covered with cushioning material such as Alpha Gel.
This structure, which maintains accurate time display and stable operation of various functions, is the core toughness performance of the Land G, supporting missions on land.
Operation and sensors that support survival
The Riku-G also boasts excellent operability, ensuring reliable access to its various functions. The buttons on the side of the watch are designed to be large, allowing for reliable operation even when wearing thick work gloves or when fingertips are covered in mud. Furthermore, the surface of the buttons is knurled for grip, preventing accidental presses even in low-visibility conditions, relying solely on tactile sensation.
The usefulness of this reliable button operation can be truly appreciated when checking the various information displayed by the group of small sensors. The Land G model is equipped with a "triple sensor" that measures direction, barometric pressure/altitude, and temperature.
The "direction measurement" helps determine direction in mountainous or desert areas without landmarks; the "barometric pressure measurement" detects rapid changes in atmospheric pressure to predict worsening weather; and the "temperature measurement" provides a numerical understanding of the current environment. The data obtained from these sensors provides valuable information to support the wearer's safety and decision-making regarding the next course of action. The practicality of the Land G is evident in its ability to instantly access this environmental data even while wearing gloves.
Top 3 Recommended G-SHOCK MASTER OF G (G-Shock) Current Models
"GWG-B1000TLC-1A"
Tough Solar. Operates for approximately 24 months on a full charge (power save mode). Carbon fiber and stainless steel case (58.7mm x 52.1mm, 16.2mm thick). Water resistant to 20 bar. Price: 143,000 yen (tax included).
This is a collaboration model with "Team Land Cruiser Toyota Auto Body," which competes in the Dakar Rally. The case and bezel are made of biomass plastic and stainless steel, and the carbon core guard structure ensures shock resistance, dust resistance, mud resistance, and vibration resistance. In addition to a triple sensor that measures direction, barometric pressure/altitude, and temperature, it is equipped with radio wave reception function (multi-band 6) and Bluetooth smartphone link function. This allows users to use a "mission log function" that records altitude acquired by the watch and route acquired by the smartphone's GPS, and a "location indicator function" that displays the direction and distance to a destination set in the app on the watch, by linking with a dedicated app. This is suitable for users who want to combine a special design with the ease of use of mobile connectivity.
"GW-9500-3"
Tough Solar. Operates for approximately 26 months on a full charge (power save mode). Resin case (56.7mm x 52.7mm, 14.8mm thick). Water resistant to 20 bar. Price: 24,200 yen (tax included).
The current latest model of the Mudman, released in 2023, is the first new Mudman model in 12 years since the GW-9300 in 2011. By revising the glass cutting and bonding methods and adopting a carbon core guard structure, a slim design with a case thickness of 14.8mm has been achieved. This reduces interference with equipment around the wrist and clothing cuffs, resulting in the advantage of not hindering movement during activities. In addition, it employs a dual-layer LCD (duplex LCD), and the upper LCD can display a large compass graphic, making it practical in situations where instant visibility is required to confirm direction of travel, such as mountain climbing and trekking. The case, bezel, and band are made of biomass plastic derived from renewable organic resources, demonstrating consideration for reducing environmental impact. Equipped with a triple sensor and Tough Solar, it is an option for people who prioritize mobility and visibility.
"GWG-2000-1A1"
Tough Solar. Approximately 25 months of operation on a full charge (in power-saving mode). Resin and stainless steel case (61.2mm x 54.4mm, 16.1mm thick). 20 ATM water resistance. 115,500 yen (tax included).
The Mudmaster GWG-2000 is a model that achieves both lightness and high rigidity by using "forged carbon," which is made by mixing finely crushed carbon fibers into resin and heat-pressing it, in part of the bezel. The complex pattern unique to this forged carbon, combined with scratch-resistant sapphire glass, gives it a sophisticated appearance despite being a tough watch. The various buttons use a mud-resistant structure that combines stainless steel pipes and silicone cushioning material. This model is suitable for those who want to include practical functions such as triple sensors and radio-controlled solar power, while not compromising on the quality and design of the watch.
The most reliable tough watch for land-based work.
The Riku G series features practical specifications designed for harsh land environments, including a mud-resistant structure to prevent foreign objects from entering the interior and a triple sensor to measure changes in the surrounding environment.
From professional use in civil engineering and rescue operations exposed to mud and muddy water, to outdoor activities such as mountaineering, camping, and motorsports, these watches maintain stable operation in a wide range of environments. In addition to the robust exterior, such as the carbon fiber case structure and scratch-resistant crystal, the operability that allows for precise handling even when wearing thick gloves is an important element that directly supports the wearer's activities.
With its unique structure that prevents malfunctions caused by mud and sand, and powered by solar energy and radio wave reception, the Riku-G watch keeps accurate time, providing reliable peace of mind as a tool watch from everyday use to harsh work environments. It is the perfect and recommended tough watch for professionals working in hard-to-reach places with mud and dust, as well as for those who take on serious mountain climbing and trekking, or for anyone who needs an instrument that can be used without worrying about weather or impact in harsh outdoor environments such as muddy camping or off-road competitions.
