Casio G-Shock Mudman watch, black and turquoise, GDG-B100-1A3ER
Black Casio G-Shock Mudman Watch with Turquoise Bio-Based Plastic Strap and 200 m Water Resistance
The Mudman is G-Shock's mud-resistant and shock-resistant model, with an angular black case shaped after the bumper structures of off-road vehicles. The case is made of bio-based plastic, and the turquoise bio-based plastic strap fits a 145–215 mm wrist. The watch measures 63.6 × 49.6 × 16.2 mm and weighs 66 g.
Under the mineral glass is a digital LCD display, and a red LED light helps in the dark. A step counter, distance, speed and calorie measurement, an interval timer and lap times make the watch suitable for training. The Bluetooth connection updates the time automatically and brings phone notifications to your wrist. Water resistance is 200 m / 20 atm, so the watch withstands swimming, water sports, snorkeling and free diving, but it is not suitable for scuba diving. The CR2032 battery of the quartz movement lasts about 2 years.
