The Casio G-Shock GMA-S2100GA-1AER men’s watch combines analogue and digital displays in an octagonal case with a black dial. Its battery-powered movement and exterior construction with an inner carbon-fibre structure help make it shock-resistant. Water resistance to 20 ATM makes it suitable for diving.
The display features a double LED light and Neobrite coating, while the hands move out of the way to keep the digital display easy to read. The automatic calendar runs until 2099, while the world time function covers 31 time zones and 48 cities, with automatic daylight saving time adjustment.
