Collection: Index Rings for G-Shock GA2100

Add a new dimension to your mod with our custom index rings for the Casio GA2100 series. Often called the chapter ring, this component sits between the dial and the crystal, framing your watch face. Replacing the stock plastic ring with a custom version is one of the most effective ways to give your "CasiOak" a premium, high-end luxury feel.

Our index rings are precision-molded to ensure a perfect alignment with the GA-2100, GA-B2100, and GMA-S2100 modules.

Customization Options:

• Luminous Indices: Features high-performance lume on the hour markers for a stunning glow-in-the-dark "diver" aesthetic.

• Metallic & Brushed Finishes: Available in silver, gold, rose gold, and gunmetal to match your metal bezel and bracelet.

• High-Contrast Colors: From "Tiffany Blue" to vibrant "Interstellar" gradients and "Rainbow" palettes.

• Stealth Designs: Matte black rings for a sleek, tactical appearance that minimizes reflections.

Pro Modding Tip: Replacing the index ring requires removing the module and crystal. We recommend pairing this with a Sapphire Crystal upgrade to complete the transformation of your watch's "face."
