It combines G-SHOCK’s legendary toughness with a modern, refined aesthetic, making it ideal for everything from casual outings to professional settings. The stainless-steel bezel and glass fiber-reinforced resin inner case provide robust protection, while the bezel itself undergoes a precise forging, cutting, and polishing process, with a beautiful circular hairline finish on the top surface and a mirror polish on the sides.

The dial stands out with a high-contrast design for optimal readability, featuring an oblong grid pattern, transparent printing, and a circular hairline finish that enhances the dimensionality of the LCD and inset dial. The metallic textures in the blue model are achieved with vapor deposition, adding a sleek, reflective quality that elevates the timepiece’s visual appeal.

Made with bio-based resin for the case and band, this watch is a step towards more sustainable timekeeping, as the material is produced using renewable organic resources, helping to reduce environmental impact. Additionally, the Super Illuminator (high-brightness double LED light) ensures you can read the watch in low-light conditions with ease.
