Summary

  Both GMA-2100 and GM-2100 are excellent watch models from Casio's G-SHOCK series, excelling in design, materials, and functionality. GMA-2100 emphasizes simplicity and robustness, while GM-2100 focuses more on a metallic aesthetic and fashion elements. Both watches offer robust water and shock resistance, as well as timing functions, suitable for various outdoor activities and daily wear. However, in the realm of modification, the watch cases and modification kits for these two models are not interchangeable. This means that parts and accessories designed for the GMA-2100 cannot be used on the GM-2100, and vice versa. This is due to differences in their design, materials, and construction, which require specific parts to maintain their functionality and aesthetic appeal.
