Men’s Silver Metal Watch: Casio G-SHOCK GMWB5000 and GMB2100
Two of G-SHOCK’s most iconic watches, the slim, octagonal 2100 line and the G-SHOCK square 5600/5000 line, now in full metal. Revel in a men’s silver metal watch backed by over 40 years of G- SHOCK protection and design. Packed with Tough Solar charging, Bluetooth® connectivity, and the shock and water resistance you need, the evolution of G-SHOCK’s full metal line is here with the Casio G-SHOCK GMWB5600 and GMB2100 series.

Iconic G-SHOCK Style: G-SHOCK Square with a Full-Metal Upgrade
A square case with a full-metal shock-resistant structure achieved through systematic evolution. The first G-SHOCK square—model DW5000C— was crafted in 1983.
That iconic square design has been reinvented with a full-metal shock-resistant structure and the latest advanced functions, including Bluetooth® connectivity and Tough Solar charging. Known for its superb style and performance, the G-SHOCK GMWB5000 men’s silver metal watch is a tough watch that climbs to greater heights.
Features of the G-SHOCK GMWB5000 Men’s Silver Metal Watch

Shock resistance achieved with a full-metal case.
The new shock-resistant structure
Fine-resin cushioning parts are inserted between the bezel case and the inner case. This redesign grants the protection needed to make a men’s silver metal watch G-SHOCK tough.

Increased airtightness specifications.
Screw-lock case back
The airtight, heavy-duty screw-lock case back, the slanted surfaces are mirror-finished, and DLC (diamond-like carbon) treatment is applied overall for enhanced wear resistance for a men’s silver metal watch.

A fusion of strength and beauty.
Bezel case
After sculpting the form through repeated forging, cutting and polishing, artisans apply mirror polishing and hairline finishing to the surfaces in pursuit of flawless beauty.

Solid feel and superior wearing comfort.
Metal band
The design of the first model’s resin band is reproduced by applying dimple-processing to the stainless-steel band pieces.

Extending attentive workmanship to unseen parts.
Inner case
After a process involving 10 or more forging and cutting steps, a complex form with integrated lugs and complicated shapes comprising various fitted and cushioning parts takes shape.

Maintaining G-SHOCK’s origins without change.
Original square design
The design of the first G-SHOCK model has been maintained continuously from the origin. Casio’s efforts in pursuit of universal usability have encompassed the structure with its undivided attention to shock resistance.

Legacy of the universal ratio.
Display aspect
The LCD’s approximately 16:10 aspect ratio approaches the angle of human vision. Adopted in pursuit of clear visibility, this ratio has been handed down from one model to another since the origin to benefit from its closeness to the Golden Ratio, which is considered to represent the most beautiful proportions in nature.

Features of the G-SHOCK GMB2100 Men’s Silver Metal Watch

Octagonal form with full-metal
design: A genuine evolution of the
original G-SHOCK DNA
Introducing the first full-metal addition to the continually evolving 2100 line, a true heir to the identity of the first-ever G-SHOCK. Boasting luxe full-metal construction while retaining the original streamlined, minimalist design along with the comfortable sizing and fit on the wrist. Also includes Bluetooth® Smartphone Link, Tough Solar, and other features designed for life in the digital age. Many enthusiasts feel the best G-SHOCK men’s silver metal watch is born from this focus on design, materials, and performance.
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 of each men’s silver metal watch 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).
