The pinnacle of MR-G, expressing the worldview of Japanese swords
The top-of-the-line G-SHOCK "MRG" line has been joined by the addition of the "MRG-B2000GA," a 40th anniversary limited edition model supervised and finished by Gassan Sadanobu, a swordsmith from the prestigious swordsmithing firm Gassan.

This is the pinnacle of G-SHOCK. It showcases the best of Casio's metalworking technology, including a recrystallized hybrid titanium bezel made from laminated 64 titanium with a cedar skin finish. It's Tough Solar. It has a power reserve of approximately five months. It measures 49.8mm wide, 54.7mm long, and 16.9mm thick. It's water resistant to 20 bar. It's limited to 500 pieces. It's priced at 935,000 yen.
One of the highlights of a sword is the texture of the jigane (iron) that is created during the forging process. This model uses "recrystallized hybrid titanium," a combination of wavy laminated 64 titanium and pure titanium, for the bezel, to express Gassan's distinctive "ayasugihada" (golden grain). The bracelet's center link is modeled after the tang (stalk) that fits into the tsuka (handle). Gassan himself filed and filed the tang with the same tang finish, and engraved the character "tempering" (forging) using the "meimeikirikiri" (mei-kirikiri) technique. The bezel, band, and case back are coated with a newly developed blue-gray AIP coating. This is inspired by the blue jigane (iron) of famous swords and the bright white of the forged blade.
Turning your gaze to the dial, the hour and minute hands and indexes are a sharp, bright white, reminiscent of a forged blade. The dial features the texture of the thread wrapped around the handle, while the controls and second hand are gold-colored, reminiscent of the ornamentation on sword fittings. The rough-looking recrystallized titanium case is treated with deep hardening and titanium carbide to enhance the material's strength and abrasion resistance. Its extensive functionality includes Tough Solar, smartphone linking via Bluetooth, and time correction function for standard radio wave reception. The large crown unit and buttons ensure ease of use.

Since ancient times, the Japanese sword has been a practical weapon, but it has also been deeply connected to the spirit of Bushido. G-SHOCK, one of the finest tool watches of the modern era, has attempted to express the worldview of the Japanese sword, which is a fitting step forward in commemorating the 40th anniversary.
