G-Shock GA-2100 “CasiOak” is the slimmest G-Shock

G-Shock GA-2100

G-Shock releases a retro-inspired analog-digital watch with the Carbon Core Guard…

The all-new G-Shock GA-2100 series is coming to Japan in August 2019. Like the recent GA-2000, the GA-2100 is a Carbon Core Guard model, but unlike other recent carbon models, it has a retro G-Shock look thanks to its octagonal bezel and traditionally shaped resin bands. The GA-2100 is actually inspired by the design and shape of the first-ever G-Shock DW-5000C but in a combination analog and digital form. At 11.8 millimeters, it is the thinnest current G-Shock watch and thinner than the DW-5600 and GW-M5610..

The GA-2100 will debut with three models: the black and gray GA-2100-1AJF, the blacked-out GA-2100-1A1JF, and the red GA-2100-4AJF. Each model has a list price of 13,500 JPY plus tax.

Features include shock resistance, 200-meter water resistance, needle withdrawal function, world time, 1/100 second stopwatch (less than 1 hour, 1-second stopwatch for one hour or more, 24 hours with split), timer (1-second, 24 hours), 5 alarms, hourly time signal, full auto calendar, 12/24 hour format, operation sound on/off, double LED lights (Super Illuminator with afterglow, 1.5/3 seconds, with LED backlight for LCD display), and estimated 3-year battery life. (The GA-2100-1A and GA-2100-4A also have Neo-Brite luminous hands.) The dimensions are 48.5 x 45.4 x 11.8 millimeters and the weight is 51 grams.

Update: Casio America released the GA2100-1A1 and GA2100-4A with a list price of $99 USD.

Update 2: The GA-2100 series has earned the nickname “CasiOak” among watch enthusiasts, due to the bezel shape’s similarity to Audemars Piguet’s Royal Oak watches.
