The Metal series introduces stainless steel into G-Shock's carbon core architecture, producing a case that holds to every toughness standard the brand is known for while offering a surface that reads differently from standard resin. The GM-2100 and GM-B2100 apply a brushed and polished steel bezel and caseback over the octagonal platform shared with the CasiOak collection, creating a watch that belongs to both the design conversation and the tool watch tradition simultaneously. Several references in the Metal range are powered by Tough Solar technology, drawing energy from ambient light and removing the battery replacement cycle entirely — for a broader look at how this works across brands, the solar movement collection at Watchello gathers the key references. Water resistance is rated at 200 metres, and the shock-resistant structure meets the same impact standards as every other Casio G-Shock. The mineral glass protecting most of these dials is one of several crystal types discussed in the Watchello guide to watch crystals. For those who approach the Metal series from the broader quartz watch category, it sits at the most considered end of the segment — technically rigorous, visually precise. The watchmaking glossary covers the construction terminology in full. Watchello ships every Metal reference internationally with warranty documentation on every order.
