Casio to Release G-SHOCK with Octagonal
Metal Bezel Metal watch based on popular GA-2100 with a slim profile and streamlined design

Norderstedt, July 15, 2021 — Casio Europe GmbH announced today the latest addition to the G-SHOCK line of shock-resistant watches. The new GM-2100 is based on the GA-2100, which is popular for its octagonal shape and streamlined design, but now incorporates a metal bezel for an even more stylish look.
Released in 2019, the base-model GA-2100 inherited the concept of the DW-5000C, the very first G-SHOCK, but was a digital-analog combination model with a slim profile and streamlined design. With its distinct octagonal shape and straightforward design, the GA-2100 has been a popular choice worldwide, particularly among young people.
The new GM-2100 retains the streamlined form and slim profile of the GA-2100, but adds a new forged metal bezel to give the watch a sharper look. A round hairline finish is applied to the top surface of the bezel and a mirror polish to the sides, giving it a beautiful metallic gleam. Options with blue-gray IP (GM-2100N) and dark gray IP (GM-2100B) bezels are available, to suit any smart style. The dials are treated with a vapor deposition finish in new navy blue, green, and red hues to achieve appealing metallic color schemes. The watch band employs a square dot texture with incremental variations in dot size, resulting in a sharp look to match the face design.
