Casio G-Shock Watch, 2100 Series, GA2100-1A1, Monochrome Black

The GA2100 family of watches was unveiled in 2019, and they’ve since become some of G-SHOCK’s best sellers. The octagonal bezel and boldly raised hour markers are popular design features. The G-SHOCK GA2100-1A1 in monochromatic black often appeals to those who don’t need a watch that announces its presence, but instead need a watch that’s admired when noticed.

Built with a Carbon Core Guard structure, the GA2100-1A1 offers incredible strength that lives up to the G-SHOCK standard in shock resistance. That strength is delivered with a slim case and compact form, an engineering feat that Casio proudly details in its history of the GA2100. The slim design is not only tough, it boasts 200m water resistance (wr 20 bar) with a case that’s only 11.8mm thick. It's clear that the GA2100-1A1 delivers impeccable performance in a sleek and compact form.

The GA2100-1A1 also conquers the dark. It houses a double LED lighting system: a Super Illuminator for the analog face is coupled with a Super Illuminator for the digital display to ensure an easy read in the dark.
