G-Shock GA-2100 Rating by G-Central
Size & Weight
The GA-2100 was an absolute sensation when it launched and resulted in a worldwide shortage of the GA-2100-1A1. This was surprising to many fans as well as to Casio, as there was not a lot of buzz about it in advance. The GA-2100 came at the right time, when people were starting to prefer smaller watches again. In just a few short years, the GA-2100 has become one of G-Shock’s bestselling models ever. It brought many new fans to the brand, many of them from the younger generation, and Casio is now fully committed to expanding the 2100 line with more advanced models, premium metal models, and smaller models for women. With a familiar yet refreshed style and clean dial layout, G-Shock has created another iconic timepiece that is suitable for both casual fashion and rugged outdoor use.

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. (Update: The G-Shock GMA-S2100 (11.2 mm) and GM-S2100 (11 mm) are now slimmer, but the GA-2100 remains the slimmest men’s model.)
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 and fans, due to the bezel shape’s similarity to the Audemars Piguet Royal Oak watches.
Based on the following photo, these watches are equipped with quick-release bands.
