Specifications
Features of GM-B2100 Series
Now in a full-metal construction, this 2100-line watch features an octagonal form inherited from the DW-5000C, 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 DW-5000C 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 GM-2100 while offering a wider range of functions and full-metal construction. While delivering high utility with Smartphone Link and Tough Solar functionality, the GM-B2100 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 vapour 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 colours for full-metal design
In addition to brilliantly gleaming silver (GM-B2100D), two other options are offered: all-black IP for an intrepid look (GM-B2100BD) and fashionable rose gold IP (GM-B2100GD).

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