Enhanced structural rigidity – reduces flex compared to resin
The alloy is lighter than steel while providing similar durability-
Perfect Fit for 3229 Module Square Series – Specifically engineered for the Casio 3229 movement – the workhorse caliber found in:
GM-5600 – the metal-bezel square series
DW-5600 – the iconic classic
GWB5600 – Bluetooth-equipped variants-
Compatible with 3229 module cases measuring 49.6 × 43.2 × 12.9 mm-
Lightweight Aluminum Construction – Crafted from high-quality aluminum – providing an ideal balance of weight and strength. Factory GM-5600 models weigh approximately 73g-. This aluminum inner case maintains that lightweight feel while offering enhanced durability compared to standard resin.
Essential for Watch Restoration & Customization – Perfect for:
Replacing damaged or worn factory resin inner cases – restore structural integrity
Custom watch builds – the ideal foundation for square G-SHOCK projects
Upgrading from resin – achieve a more premium internal structure
Keeping a spare module shell – essential for modders and repair professionals
Compatibility Note – Confirm Before Ordering – The GM-5600 features larger buttons than the standard DW-5600-. While the 3229 movement is common across square models, inner case dimensions may vary. Please confirm compatibility with your specific model before ordering – GM-5600 inner cases are not identical to DW-5600 cases.
OEM-Spec Alternative – Precision-crafted to match original Casio specifications. A cost-effective solution compared to sourcing OEM service parts. Note: These are aftermarket replacement parts, not genuine Casio® parts. The aluminum inner case is a modding upgrade – factory GM-5600 models use resin inner cases-.
