Full metal shock-resistant structure with precision refinement

Buffering components made of fine resin are installed between the stainless-steel bezel and case to protect the module from shock. Undergoing meticulous processes of forging, cutting, and polishing, the bezel and case are precisely crafted down to the intricately shaped face, and also to the back, which is the key to the precision fit. Additionally, a three-pronged structure is employed for the lugs on the case to disperse shock to the connective part of the band.




Three distinctive IP colors for full-metal design                                                                            

In addition to brilliantly gleaming silver (GMB2100D), two other options are offered: all-black IP for an intrepid look (GMB2100BD) and fashionable rose gold IP (GMB2100GD)


Solar-powered timekeeping with Bluetooth® for enhanced accuracy and reliability

Dual-layer dial construction is employed to present the inset dial and LCD portion with distinct finishes of their own. With a minute grind-mark finish and vapor deposition applied to the inset dial ring, laser welding used to secure it to the dial, and more, precision die moulding technologies applied by Yamagata Casio deliver an intricate form and meticulously detailed surface finish. In addition, the vapour deposition applied to the dimensional index marks and the indicator hand emphasises the metallic texture for a dial design that complements the watch’s metal exterior.
