Looking to refresh your Casio G-Shock GA2100, aka the Casioak?

This is a 100% genuine Casio replacement set for the band and bezel, all in that classic stealth black.

The rubber material feels just like the original because it is the original—same softness, same durability.

The band width is 16mm, designed to fit perfectly with the GA2100 series.

Everything comes new with tags attached, so you’re getting authentic parts that haven’t been worn or handled.

Whether your current strap is worn out or you just want to switch up the look, this kit gives your watch a fresh, factory-style finish.
