Casio Debuts Blue Sapphire G‑SHOCK in 20‑Piece MR‑G Limited Run

Overview

• Casio announced Thursday that the MRG‑D5000 will be released in a 20‑piece limited edition and that two additional blue‑sapphire‑accented models will join the drop.
• The watch achieves shock resistance by using a proprietary, screwless Multi‑Guard Structure that assembles multiple interlocking sapphire components to avoid stress at screw holes and disperse impact.
• Key G‑SHOCK functions are retained: the new models are water‑resistant to 200 meters, use solar charging (Gallium Tough Solar), and include radio timekeeping plus standard timers and alarms.
• Media reports place the flagship MRG‑D5000 at about $80,000 (WIRED) and £67,000 (British GQ), making it the most expensive G‑SHOCK to date while the two lesser models carry much lower price points.
• Production will be tightly constrained because sapphire ingots take months to grow and the new outer‑case assembly requires specialized jigs and skill at Yamagata Casio, a factor that will reinforce scarcity and boost collectibility.
