G-Shock Introduces the “Extra-Thin” GA-2100 Carbon Core Guard

Lightweight and wearable.

The new G-Shock GA-2100 is likely the most wearable in the line-up, being the thinnest G-Shock ever. Its compact dimensions – and analogue hands – gives it the feel of a conventional watch, avoiding the extremely oversized style of many G-Shocks.

Just 11.8mm high, the GA-2100 is thinner than the Omega Speedmaster Moon Watch (13mm) and the Rolex Daytona (12.2mm). The case diameter is 45.4mm, though it looks and feels substantially smaller.

Though reduced in size, the GA-2100 has the traditional G-Shock case construction that includes an inner protective bumper around the electronic module.

Visible around the steel case back, the bumper is made of carbon composite – which Casio has named the Carbon Core Guard – which is a dark marbled grey and distinct from the black resin outer case.

The octagonal bezel is immediately reminiscent of the Royal Oak, but according to Casio it is actually a reworking of the bezel of the original G-Shock of 1983, the DW-5000C, which was octagonal, albeit one with unequal sides.

The GA-2100 has an analogue displays for the time and day of the week, but also all the usual electronic functions of a G-Shock in two LCD windows, including multiple time zones, stopwatch, alarm, countdown and calendar.
