Our take on the Casio G-Shock Digital Red Mens Watch G7900A-4D

The Casio G-Shock G7900A-4D is a digital sports watch built around a tide graph and moon phase display, aimed at surfers, anglers and other tide-dependent outdoor users. It pairs a 52.4mm red resin case and band with shock resistance, 200-meter water resistance and low-temperature operation down to -20°C. Feature depth is its edge over simpler G-Shock models: world time, dual stopwatches, countdown timer, multiple alarms and an EL backlight. Against the GW-7900, it lacks solar charging and radio timekeeping, so it is the more basic version of the same tide-focused design.
