How to find a verified modder for Casio G-Shock watches
CasiOak and full-metal custom builds. We connect you with verified workshops — not anonymous resellers.

Why Casio G-Shock modding matters
The GA-2100 "CasiOak" created a second modding universe: ultra-thin G-Shock core inside steel or titanium cases, integrated bracelets, and luxury-inspired bezels. Unlike Seiko, mods are mostly aesthetic — but demand for professional assembly and finishing is rising fast.

FAQ — G-Shock modding
Answers collectors ask before commissioning a modder.
Which G-Shock is best for modding?
The GA-2100 CasiOak is the most modded model worldwide. Its slim profile accepts hundreds of aftermarket metal cases and bracelets. The classic DW-5600 square is a simpler entry point for strap and bezel customisation.
Do I need a modder for a CasiOak metal kit?
Many kits are marketed as DIY, but professional assembly ensures proper button alignment, water resistance, and scratch-free finishing. If you invested in a premium kit, a modder protects that spend.
Will modding void my G-Shock warranty?
Opening the case or installing third-party parts typically voids Casio's manufacturer warranty. Reputable modders document their work and may offer their own short warranty on assembly.
Are G-Shock mods waterproof after a metal conversion?
Water resistance depends on gaskets, case integrity, and assembly quality. Ask your modder whether they pressure-test and to what depth — do not assume 200 m ratings from kit marketing alone.
How much does a CasiOak mod cost?
Budget €50–120 for basic bezel or strap mods, €80–180 for popular Royal Oak-style kits (parts only), and €150–350+ with professional assembly and premium finishes.
