Metal Elegance: Silver Full-Metal G-SHOCK GMB2100D-1A Watch
Elegance expressed in forged steel beating with the heart of G-SHOCK’s water and shock resistance: that’s the GMB2100D-1A. The silver full-metal construction undergirds an array of performance tech and radiates sophistication. The polished metal offsets the vapor deposition finish of the black dial, demanding equal attention between the metal bezel and the detail of the dark watch face. The full-metal GMB2100D-1A is a powerhouse of performance, style, and durability.
The G-SHOCK GA2100 series was released in 2019, and the popularity of the series has spawned innovative iterations. The Full Metal GMB2100 series is one such iteration, conceiving the GA2100 as a full-metal construction. But the innovation isn’t only aesthetic. We upped the ante by including Tough Solar charging and Bluetooth connectivity.
How does one create a full-metal watch and yet offer shock resistance? We crafted resin buffer components between the metal elements to ensure the GMB2100D-1A lives up to the G-SHOCK standard in shock protection. Stainless steel ensures the watch is resistant to corrosion, and the protection features are rounded out with 200m water resistance (wr 20 bar).
That’s G-SHOCK.

Features of GM-B2100 Series
PROMOTION MOVIE
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.
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.
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.
DETAILS

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.

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).
