Casio released full-metal G-SHOCK in gleaming Yellow-Gold Hue - TGH Technology and Business Portal/Blog

Casio Computer Co. Ltd recently announced the release of a new watch addition to the G-SHOCK brand of shock resistant watches. The new GM-B2100GD-9A features a full-metal design with an iconic octagonal bezel, now in stunning and gleaming new yellow-gold hue.

GM-B2100GD-9A is the new model announced, it’s a shock resistant timepiece presented in a glittering yellow-gold hue, offering a new colour option for those GM-B2100 models. Yellow-gold IP is applied not only to the bezel and band, but even to minute facets of the design such as the side buttons and screws. Separate applications of a hairline finish to the top surface of the bezel and a mirror finish to its subtly sloping sides enhance the textural look of the gorgeously gleaming metal.


The yellow-gold colour exudes a subtly distinctive character, making it versatile and suitable for casual or formal occasions.
