Casio G-Shock GA-2100 Series

The budget G-Shock model with an octagonal case and the latest Carbon Core Guard protection. The GA-2100 form factor resembles the first G-Shock DW-5000C, but with a pronounced octagonal shape and more streamlined corners – this way the Japanese pay tribute to the glorious past of the high-impact direction. The carbon fiber that is used in the GA-2100 case makes the watch more durable and lighter, not to mention the case thickness of 11.8 mm – the series can be called the thinnest among all G-Shock with an analogue dial. An additional window shows the current day of the week, and more detailed information about the date can be viewed on the digital display. The set of features here is only basic [world time, timer, stopwatch, alarm clock, calendar], but they are enough for most everyday tasks.

Official Marketing Focus from Casio

Ever since the first DW-5000C went on sale back in 1983, G-SHOCK has continued to push the limits of timekeeping toughness while creating new and original designs. These new models embody these efforts in an attractively thin configuration.
These new models inherit the octagon form that was also employed for the original DW-5000C. Analog-digital timekeeping comes packed into a no-nonsense simple design without sacrificing G-SHOCK level toughness.
High-strength resin material, which is reinforced with carbon fibers, makes it possible to create a case that is a mere 11.8 mm thin, which is the thinnest among G-SHOCK combination models.
