Suppaparts adapters are used to replace your original rubber strap on the Citizen dive watches nicknamed Eco-Zilla and Auto-Zilla, and now the new Depth Meter series (BN2021, BN2024, BN2025, BN2029). This allows you to attach a variety of straps to your watch including a bracelet, leather, nylon zulu or nato, or more flexible rubber straps. We now offer adapters to fit most Casio G-Shock watches. Our Suppa-G adapters will fit the watches that have a 16mm gap in the back once you remove the original strap. Suppaparts is not associated with Citizen Watch Company or Casio G-shock, we are an independent producer or aftermarket parts.
