Timeline of older watch models,  1983 DW5000C, 2019 GA-2100, ending with 2022 full metal GM-B2100

A full-metal analogue watch,
heir to the spirit of
the very first G-SHOCK

Now in a full-metal construction, this 2100-line watch features an octagonal form inherited from the DW5000C, the very first G-SHOCK that debuted in 1983. With its screw-back case, bezel and band crafted with stainless steel, the watch offers a streamlined, minimalist design while protecting the module from drops and impacts with its iconic G-SHOCK shock-resistant structure. With its tough, dimensional forged form, the bezel shines with an attractive circular hairline finish on its top surface. Reproducing the dimpled portions of the DW5000C in metal, the band presents enhanced textures with differentiated hairline and mirror finishes.

Slimline module design achieved
with high-density mounting

Employing a slim Tough Solar powered timekeeping module with Bluetooth® connectivity, the watch maintains the same sense of size as the previous GM2100 while offering a wider range of functions and full-metal construction. While delivering high utility with Smartphone Link and Tough Solar functionality, the GMB2100 offers a comfortable fit on the wrist as well.

GM-B2100 parts separated in a stack to highlight sturdy construction and materials

Full metal shock-resistant
structure with precision

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.

Dial finishing achieved with microfabrication technology

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.
