Casio Japan announced a new Master of G series featuring a vintage-inspired black and gold color scheme. Like the previous analog-based Black and Gold Master of G Series, this new series features a land, sea, and air theme with Mudmaster (GG-1000GB-1A), Gulfmaster (GN-1000GB-1A), and Gravitymaster (GA-1100GB-1A) models but features the more affordable Twin Sensor battery-powered versions. All three models feature shock resistance, 200-meter water resistance, world time, stopwatch, timer, 5 alarms, full auto calendar, and LED light.
