Important Notes
Always confirm your Casio G-Shock model number before purchasing to ensure compatibility with the listed models. While this set is designed for the specified G-Shock variants, it may not fit other models or generations. Use only the provided cross-head screwdriver or a precision driver of equivalent size to avoid damaging the screw heads. Over-tightening can compromise the case seal or strip the threads—apply even, moderate pressure during installation. Store the screws and tool in a dry, cool environment to preserve their condition over time.
