G-Shock G-Steel 2100 Series. GM2100YM-8A - The "Mirror Mirage" CasiOak

The GM-2100YM-8A is a masterclass in Optical Depth. Designed in collaboration with the Tokyo graphic artist YOSHIROTTEN, the watch explores the theme of "Music and Light." The stainless steel bezel features a sophisticated vertical hairline finish that gives it a raw, industrial "brushed" texture, which then transitions into a high-mirror-polished dial.

The dial itself is a work of art: it features a vapor-deposition finish that reflects light like a calm sea or a silver screen, accented by a single, vibrant orange data line that cuts across the face—inspired by the neon glow of a digital sunset.

Key Performance Features

Forged Stainless Steel Bezel: A solid metal cover forged and polished to provide an elite, "executive" weight and a light-catching octagonal profile.

Translucent "Smoke" Resin Band: A semi-transparent grey strap that provides a ghostly, "Cyber-Tech" frame for the heavy silver metal head.

Mirror-Finish Dial: A specialized metallic coating that makes the analog face look like a liquid mirror, creating a 3D effect as the hands move above it.

Orange "Afterglow" Accents: Minimalist orange-tinted graphics on the dial evoke the "high-tech data" aesthetic found in Tokyo’s most modern digital districts.

Carbon Core Guard Structure: An internal carbon-fiber-reinforced resin case ensures the watch remains incredibly slim (11.8 mm) while maintaining "Unbreakable" shock resistance.

Double LED (Super Illuminator): Features high-intensity white LEDs for both the analog face and the digital display, making the mirror finish pop in the dark.

200m Water Resistance: Fully professional-grade protection—this "Designer Piece" is still a tank in the water.
