Built for Mud and Shock

The GG10001A3 Mudmaster is a men’s sports watch with a 55.3mm resin case and matching resin band. Quartz movement drives an analog and digital display with index markers at 12, 3, 6 and 9 o’clock. The green colourway uses a buckle fastener and the band is adjustable for adult wrists.

Check Strap Length and Display Preference

Band length is 8 inches and the buckle allows resizing, so confirm the fit suits your wrist. The watch combines analog hands with a digital window, so decide whether you want both formats before ordering. Water resistance is rated to 200 metres, making it suitable for swimming and surface water sports.

Suits Outdoor Workers and Field Navigators

Digital compass shows 16 bearing points with 1-degree resolution and bearing memory, while the thermometer reads -10 to 60 °C in 0.1 °C steps. World time covers 31 zones across 48 cities plus UTC, and five daily alarms plus hourly signals keep schedules on track. Buyers who want a slimmer profile or a purely analog face should look elsewhere.

Questions about this item

What comes in the box and do I need to buy a strap or tool separately?

The watch ships with its resin band already fitted and a buckle fastener, so no extra strap or sizing tool is required.

Should I choose the 55.3 mm or 56.2 mm case version?

Both figures refer to the same model; the 55.3 mm case diameter is the standard spec and the 56.2 mm highlight is an alternative measurement of the same watch.

How accurate is the digital compass when I am actually hiking?

The compass reads direction in 16 points with 1-degree resolution across 0 to 359 degrees, supports bidirectional calibration and magnetic declination correction, and stores a bearing memory for navigation.
