The sharp, strong form of the mid-size octagonal metal G-SHOCK is the hallmark of its original design. With stainless steel surrounded by a hairline finish, this tough bezel is extremely stylish. The face is finished with a metallic opaque finish and detailed details that match the classic metal G-SHOCK. The addition of a rough, angular surface on the band gives the casual urethane material a fresh edge. Choose your message in silver, blue, gray, or gray and red.

Ever evolving toughness:
Metal-clad shock-resistant structure

A stainless steel bezel with excellent rigidity and an inner case made of resin reinforced with glass fibers are resistant to damage and deformation. Protects the module. A small protrusion on the inner case reduces surface contact with the bezel to absorb impact from the module. Cutting-edge technology has been applied to G-SHOCK's unique hollow structure concept to create a shock-resistant structure with a metal exterior.
The bezel features the octagonal design that G-SHOCK has used since the first model. Through careful molding, cutting, and polishing, the bezel is precisely constructed, from the delicately shaped face to the design of the back, which is the main factor in accurately producing the inner case. A rounded hairline finish is applied to the top surface and the glass surfaces and sides, giving the bezel a beautiful glossy sheen.

Octagonal form exudes toughnes

Minimalist beauty of form:
Wafer-thin design

We achieved shock resistance from a minimum case thickness by employing an impact-resistant metal structure. The installation of a high-density circuit board structure allowed the module size to be further reduced. The result is a slim design excellent for an analog-digital combination model with a metal case and a comfortable fit on the wrist.
Casual Style:
Patterned Strap
The watch's urethane strap uses a square dot pattern in detail. Advanced casting technology is used to achieve the delicate pattern with gradual changes in the size of the dots. The slider makes it easy to put on and take off the strap.
Exquisite details:
The dial has a metallic vapor deposition.
A mirror finish and a hairline finish have been applied to the dial surface to create the pattern of the metal model, maintaining the high level of attention to detail.
Unique IP colors
The watch comes in three color options: silver, which highlights the metal pattern (GM-2100), IP dark blue (GM-2100N), and IP dark gray (GM-2100B). These classy colors elevate the watch to true fashion item status.
2019: The GA-2100
The first GA-2100 model was released in 2019, expanding the possibilities of analog toughness and style. The GA-2100 utilizes the latest technology to express its identity in a new physical form. It inherits the conceptual design structure of the DW-5000 and AW-500, which set a new standard for G-SHOCK, and reuses the concept from the point of advantage of the brand's inception. It has now been 30 years since the release of the AW-500.

New style of G-SHOCK watch

DESIGN
1983: DW-5000
The first G-SHOCK, the DW-5000, was released in 1983. Its timeless design, perfected from the ground up, was born from the pursuit of extreme toughness to avoid external limitations.
1989: AW-500
The design concept was inherited by the first analog G-SHOCK, the AW-500, released in 1989. This concept is reflected in the robust design that appears to be carved from a single block of resin, eliminating all unnecessary elements.
New technology, new design
Development Concept: Slim and Compact The commitment to avoid external limitations is not only evident in the design, but also in the size, using revolutionary new technologies, from the slim module to the carbon core guard structure. In order to achieve this concept, by refining the original DW-5000 design, the watch presents a newly created form that perfectly blends with contemporary lifestyle and fashion.

Paris, Hamburg, New York, and Shanghai have all been impressed by design works from all over the world. Countless sketches and designs were reviewed in a painstaking trial and error process. Finally, a new watch was born. It features a minimalist design with an octagonal frame.

I have been using it for about 2 days now, even when washing hands, taking a shower or exercising, it still works fine. I haven't tried swimming yet, but I watched a video where he dipped the watch in water for 1 hour and it still worked fine. I am very impressed with the waterproof feature.

Very impressed with this watch, didn't expect it to have so many interesting functions. It's worth experiencing Casio G Shock products.
