Join the G-SHOCK 40th anniversary celebration in luxe quality and style with a limited-edition timepiece from the G-SHOCK flagship MR-G line of timepieces honoring artisanal craftwork. Dedicated to traditional Japanese artisanal techniques handed down over centuries, this timepiece celebrates samurai warrior pride and aesthetics with a design that incorporates the Shougeki-Maru: Gai, the kabuto helmet Casio commissioned for the MR-G line. The bezel captures the maedate crest of this very special helmet with a tiger design and rock-grain relief intricately engraved by metalsmith KOBAYASHI Masao. Each limited-edition timepiece is a one-of-a-kind, hand-engraved by a master craftsman. The pure white Dura Soft fluoro rubber band evokes the look of the white ito odoshi*1 used in crafting traditional Japanese armor. A deep-layer hardening process and dark silver AIP® are applied to the recrystallized titanium case to express the color of the Shougeki-Maru: Gai helmet. An engraved metal plate commemorating the G-SHOCK 40th anniversary on the case side at the 10 o’clock position adds a touch of edgy styling, as do the four lab-grown rubies*2 in the bezel symbolizing 40 years. More than just an homage to tradition, this timepiece provides superior modern functionality, as well. Equipped with Bluetooth® for smartphone connectivity, the watch adjusts to radio-wave time signals for precision timekeeping and comes packed with handy functions powered by original Casio technology. This very special, 40th anniversary-worthy MR-G celebrates both the traditional craftsmanship and modern technologies of Japan — all in a singular samurai-inspired timepiece.　 *1 White ito odoshi: The white string that binds the plates of the shikoro armor together. The pure white color symbolizes the strong determination of a warrior who stays true to their own convictions, unaffected by others (as in the white undyed by other colors). *2 The heads of the screws securing the bezel are set with rubies lab-grown by Kyocera, a material selected out of commitment to ethical considerations. Since ancient times, rubies have been known as the “stone of victory” and were believed to carry the energies of triumph over difficulty and victory.
