The GA-2100 is a hugely popular series of analog G-Shocks. It's a fairly recent model and combines the simplicity and spirit of the first analog G-Shock, the AW500, with the octagonal "Casio Square" shape of the first ever G-Shock, the DW5000C. Despite drawing from Casio's own history, the GA-2100 bears a resemblance to another famous watch, which has led people to call this the CasiOak.

The GA-2100 series is among the lightest and smallest of G-Shocks available. This has been achieved with Carbon Core Guard, allowing the size of structural components to be reduced while achieving at least the same strength, probably better.

These watches are popular for a reason, and people modify Ga-2100s with custom accessories made by other manufacturers. It's a solid choice if you want an affordable G-Shock with an analog display. The watch – like all Analog / Digital Casios – has a hand shift feature that reveals the display in case it's block o' clock. Just press Mode and Light together.
