First introduced in 2019, the G-SHOCK 2100 series quickly gained popularity due to its recognizable octagonal case.
Since then, Casio has expanded the range of models united by this distinctive design. For several years, the brand offered luxury versions of the 2100 series within the premium MR-G line, but the 2026 release takes the style to a new level in a more accessible segment. The Casio G-SHOCK Luxe Black collection includes four models from the 2100 series with black elements and sleek metallic accents.
Design and Features of the G-SHOCK Luxe Black Collection
The four models in the collection are based on the original 2100 series design, debuted in 2019, but they are not just new color options. All watches feature matte black dials with a fine texture that absorbs light and reduces glare. Elongated hour markers and thinner hands create an elegant execution of the analog-digital GA2100 display. To enhance sophistication, the hour markers are coated with a metallic finish, adding a subtle shine that contrasts with the model's inherently sporty and rugged nature.
Models with Plastic Bezel: GA2100LXB-1A and GA2100LXB-1A9
The first two models in the collection - GA2100LXB-1A and GA2100LXB-1A9 - are based on the classic GA2100 case with a plastic bezel. With a diameter of 45.4 mm, a thickness of 11.8 mm, and a lug-to-lug length of 48.5 mm, the watches have an inner carbon composite case covered by a matte black plastic bezel. The top of the case is protected by flat mineral glass, and the case back is made of stainless steel secured by four screws. The straps are made of black bio-based resin with a classic channel pattern, emphasizing the overall style.
The main difference between these two models is the metallic accents on the dial. The GA2100LXB-1A features a restrained design with silvery hour markers on a matte black background, which continues on the bezel and strap. In contrast, the GA2100LXB-1A9 offers a more expressive look with gold-toned hour markers and gold details on the day-of-the-week indicator at the '9 o'clock' position. Enhancing the color scheme, the GA2100LXB-1A is equipped with a traditional inverted LCD display, while the GA2100LXB-1A9 features an inverted screen with amber numerals. These nuances and updated dial proportions create a more refined version of the classic GA2100 with a plastic bezel.
Models with Metal Bezel: GM2100LXB-1A and GM2100LXB-1A9
The other two models in the collection - GM2100LXB-1A and GM2100LXB-1A9 - are based on the more premium GM2100 version with a metal bezel. In these watches, the plastic bezel is replaced with a black stainless steel bezel with ion plating, significantly elevating the style. Additionally, thin metallic rings are applied to the inner side of the mineral glass by vapor deposition, highlighting the outer edges of the display.
Like the models with plastic bezels, the GM2100LXB-1A and GM2100LXB-1A9 have stainless steel case backs, but their straps feature a checkered texture instead of channels. All four models in the collection offer shock resistance and water resistance up to 200 meters, meeting G-SHOCK standards.
The GM2100LXB-1A is executed in a monochrome color scheme with a matte black dial, silver hour markers, an inverted LCD display, and a bio-based resin strap with a checkered texture. A notable visual detail is the silver metallic ring around the glass. The GM2100LXB-1A9 stands out with golden elements on the LCD display, dial accents, and metallic ring, but unlike its plastic counterpart, the hour markers here are not gold-toned.
Technical Specifications and Functionality
All four models are equipped with module No. 5611, powered by two SR726W batteries with a lifespan of about three years. Despite the lack of solar charging and Bluetooth, the module offers a useful set of features:
- stopwatch with 1/100-second accuracy;
- countdown timer;
- five daily alarms;
- world time mode with presets for 48 cities;
- dual LED lighting.
Module No. 5611 is also used in the original G-SHOCK GA2100, so the new models retain the familiar interface and functionality while offering a more refined and minimalist design.
Conclusion: Affordable Luxury in Classic Octagonal Design
In recent years, Casio has added elegance to the G-SHOCK 2100 series through the MR-G line models, but they are targeted at enthusiasts and come at a high price. The G-SHOCK Luxe Black collection offers refined details and premium accents in a more accessible segment, retaining the recognizable octagonal silhouette. Thin hands, elongated hour markers, and concise color solutions give the watches a more formal and stylish appearance.
All four models in the collection are based on the GA2100 and GM2100, ensuring their accessibility within the overall G-SHOCK range. Models with plastic bezels (GA2100LXB-1A and GA2100LXB-1A9) are priced around $145 USD, while the versions with metal bezels (GM2100LXB-1A and GM2100LXB-1A9) cost approximately $260 USD. Thus, Casio offers brand fans and a wide audience stylish and functional watches with a recognizable design at a moderate price.
