GA-2100 Metal Mod Kits: Turn a CasiOak Into a Steel Watch
In short
A GA-2100 metal mod kit replaces the resin case cover and band of a G-SHOCK GA-2100 with stainless steel parts, so the watch looks like a full-metal piece while keeping its own movement and dial. We carry plain steel and frosted steel kits, one of them in silver, black, gold and rose gold. A kit is the metal parts only: you supply the GA-2100.
What is a GA-2100 metal mod kit?
A metal mod kit is a set of stainless steel parts made for the GA-2100: a metal case that takes the place of the resin bezel, and a steel band that takes the place of the resin strap. The result is an octagonal steel watch with the GA-2100's analog-digital dial.
Mod kit or moissanite bezel?
A moissanite bezel changes the bezel only and adds stones; the watch keeps its resin band. A mod kit changes the bezel and the band and gives the whole watch a metal look, with or without an iced finish. Choose a bezel for sparkle and a kit for a full metal watch.
Mod kit or a Casio GM-2100?
Casio's own GM-2100 has a stainless steel bezel over the same octagonal shape and weighs 72 g in stock form, against 51 g for the resin GA-2100. It keeps a resin band. A mod kit goes further, with a steel band as well, but it is an aftermarket part, not a Casio product, and a steel kit makes the watch noticeably heavier than stock.

These are the kits currently in the catalog.
Fitting a mod kit
Fitting a kit has more steps than a bezel swap, because the band changes too. Follow the instructions that come with the kit, or have a watch repair shop fit it. Custom modifications can affect water resistance, so confirm with us before swimming with a modified watch.
Common questions
Does a GA-2100 mod kit include the watch?
No. A mod kit is the stainless steel parts only. You need a GA-2100 to fit it to.
Do GA-2100 mod kits fit the GA-2110?
One of our steel kits lists both the GA-2100 and the GA-2110. Check the fit line on each kit's product page, and contact us if your model is not named.
Is a mod kit made by Casio?
No. Mod kits are aftermarket accessories. GshockVendor is an independent store and is not affiliated with Casio.
