Expressing the beauty of Japanese armor and helmets with the traditional kurogane-iro hue: Melding tradition and innovation for a regal sense of presence

Kurogane-iro (literally “iron color”) is a rich, dark blue-green hue that iron takes on when heated. Revered as a traditional Japanese hue imbued with refined elegance, this distinctive tone is brought to life on the titanium exterior components using a meticulous process combining deep-layer hardening and a green DLC coating. This finish not only enhances the material’s strength but also achieves a profound depth of color, embodying the essence of Japanese aesthetic sensibilities. The result is a bold yet understated presence that captures the MR-G spirit — an unwavering pursuit of both strength and beauty.

Recrystallized titanium is employed for the bezel, showcasing a distinctive crystalline pattern to evoke the nie crystals visible in the temper pattern of Japanese swords. A green DLC coating is applied to the bezel, as well as the titanium case. Flexible fluoro rubber offering outstanding durability is used for the band, which features a geometric bishamon kikko tortoiseshell pattern — a time-honored symbol of strength appearing on the warrior-deity Bishamonten’s armor and helmet.
