It delivers the shock-, dust-, and mud-resistant structure that defines the MUDMAN identity while also providing a superbly comfortable fit on the wrist.

The MIP LCD delivers outstanding readability, even in direct sunlight. The red LED backlight enhances watch visibility during nighttime activities while also helping preserve the eyes’ natural adaptation to the dark.

G-SHOCK GDG-B100

Bumper guard design for an even tougher and more refined piece of gear

The exterior design evokes protective structures used on off-road vehicles and survival gear. The design places the centre case between the multifaceted front bezel and back bumper bezel to help absorb shock from all directions. In addition, the bezel and band interlock to increase the strength of the band connections. With its combination of components featuring intricately moulded forms, including dimensional moulding of the back bumper bezel into a shape made to fit comfortably on the wrist, the structure delivers both the practical utility needed in the field and a solid, rugged design sensibility.

Mud-resistant structure to withstand use in the harshest conditions

Carbon fibre-reinforced resin increases the rigidity of the case, resisting damage and deformation to ensure an airtight seal. The button shafts are fitted with gaskets to prevent the intrusion of mud and dust. The case back is engraved with the iconic MUDMAN mole character racing across harsh terrain. The rugged tread pattern from the mole’s boot is echoed on the watch face and band, symbolically expressing the mud resistance that defines the MUDMAN identity.

MIP LCD with red LED backlight ensuring around-the-clock readability

The watch features an MIP LCD that provides high-definition display of the time, measurement data, and more, delivering outstanding readability even in bright outdoor spaces and direct sunlight. An auto LED backlight ensures visibility in low-light conditions as well. The red LED, which is gentler on the retinas, helps users’ eyes stay adapted to seeing in the dark, making it ideal for nighttime activities.

Training functions to support active lifestyles

In addition to stopwatch timing, the watch measures distance,* speed, pace, and calories burned. The watch also stores up to 100 lap times and includes an interval timer for training, while also offering step counting via an accelerometer. Measurement data can be sent to a paired smartphone, where the app helps manage daily exercise logs.

Vibration alerts for important updates

Watch vibrations can notify users of elapsed time, calories burned, and more during training, as well as incoming calls, emails, and social media notifications from a Bluetooth®-connected smartphone.

Smartphone Link

Connects to a smartphone via Bluetooth®. The app makes it easy to configure various watch functions, manage training data, and more.
