Preserve Your G-SHOCK’s 200m Water Resistance – G-SHOCK watches are rated for 200 meters (20 BAR) of water resistance-. The case back gasket is the critical component that maintains this waterproof rating-. Over time, rubber gaskets can dry out, harden, crack, or lose their elasticity-. Replacing a worn gasket restores the water-resistant seal, protecting your watch from moisture damage.
Essential for Watch Service & Battery Replacement – Perfect for: Routine battery replacement – replace the gasket when servicing your watch; Restoring water resistance – after years of wear, gaskets degrade and lose sealing ability-; Complete watch restoration – the essential seal for any G-SHOCK service project; DIY watch repair – a straightforward replacement for experienced enthusiasts. When replacing the gasket, apply a thin layer of silicone grease to the seal to enhance its waterproofing properties-.
Proactive Maintenance – Extend Your Watch’s Lifespan – Watch manufacturers typically recommend replacing waterproof seals every 2 years to ensure optimal water resistance-. A degraded gasket is one of the most common causes of water damage in G-SHOCK watches. Replacing it proactively prevents costly moisture damage to the movement and dial. A small investment in maintenance that extends the life of your timepiece.
OEM-Spec Alternative – Precision-crafted to match original Casio specifications. A cost-effective solution compared to OEM service parts. Note: These are aftermarket replacement parts, not genuine Casio® parts. However, they are engineered to the same specifications as the original gaskets used in Casio G-SHOCK watches. Please confirm your watch’s full model number before ordering – model numbers are engraved on the case back-.
