Add to compare

The GDG-B100 is the first Mudman and the third Master of G model with a high-contrast MIP LCD display. It is essentially a beefed up GBD-200 (with a step tracker and Bluetooth), with a bumper guard design featuring a Carbon Core Guard case, a mud-and-dust-resistant button structure that can be operated with gloves, stronger band connections, and a red-colored LED backlight. Other notable features include vibration alerts, phone notifications, interval timer, and measurement for distance, speed, pace, and calories burned, with distance measuring calibration available with a GPS-equipped smartphone for future offline measurements. The GDG-B100 is an October 2026 release in Japan and Asia, with other regions expected to follow.
