Inspired by the art of forging Japanese katana swords, the MRGB2000JS embodies the majestic strength and gorgeous beauty of the Juryoku-Maru: San, the katana commissioned by Casio for the flagship MR-G line of timepieces that feature carefully selected colors, materials, and finishes. The timepiece epitomizes the katana world and Japanese aesthetics, imbued with the soul of craftsmanship and incorporating cutting-edge technology throughout. The bezel is made of recrystallized hybrid titanium to evoke the distinctive temper pattern of the sword blade, and the textured band in aogai blue shell lacquer is inspired by the look of Japanese sword scabbards. The MR-G line is all about fusing tradition and innovation, and this vision is reflected in every detail of this very special limited edition of just 800 pieces worldwide. The design of the MRGB2000JS1A is the result of a remarkable collaboration between Casio and two celebrated Japanese artisans. Teruhira Kamiyama, a rising star in modern Japanese swordsmithing, is renowned for his award-winning craftsmanship, including receiving the Chairman's Award in the Sword Making Section at the 2023 Craftsmen's Competition in Japan. His contributions to the MRGB2000JS1A include the intricate blade pattern and the special engraving "San," which pays homage to the artistry of traditional sword-making. Mamoru Nomura, a "Traditional Master Craftsman" certified by the Japanese government in 2001, brings his expertise in the ancient "Raden" technique to the design. This delicate lacquer craft, using blue shellfish, is reflected in the intricate detailing that adorns the timepiece, highlighting the centuries-old traditions that influence its creation.
