Casio G-SHOCK GM-B2100

The best-selling G-SHOCK 2100 series from Casio now welcomes a full-metal variant, the GM-B2100.

GA-2100 was introduced in 2019 as a modern interpretation of the very first G-SHOCK, the DW-5000C. Thanks to its streamlined, minimalist design and the attractive octagonal bezel design, this model became a highly sought-after contemporary timepiece.

The new “CASIOAK” with metal design proudly features iconic octagonal bezel of the 2100 line. The Casio G-SHOCK GM-B2100 watch employs stainless steel as the exterior material for the case, band, and bezel.

In order to ensure shock resistance, the shock-resistant structure created for the iconic shape of the full-metal GMW-B5000 was adopted for the screw-back case, band, and bezel joints of these watches as well, with buffering components made of fine resin installed between the bezel and case.

Solid and stylish, the octagonal bezel of G-SHOCK GM-B2100 was made using multiple processes: forging, then cutting and polishing.

To accentuate the beauty of the metal, the components are treated with different finishes — the bezel with a circular hairline finish on its top surface, the band with a vertical hairline finish, and the bezel bevel, buttons and case back with a mirror finish.

The dial is composed of multiple parts to create depth and dimension, while the inset dial ring at the 9 o’clock position and the index marks are treated with a vapor deposition finish.

The new Casio G-SHOCK GM-B2100 watches are powered by a Tough Solar charging system that eliminates the need to regularly replace the battery.
