Casio to Release MR-G Crafted in Blue Sapphire Crystal
The watch uses a screwless sapphire-crystal structure and is capped at 20 pieces worldwide, Casio said.
- On Thursday, October 1, 2026, Casio Computer Co., Ltd. unveiled the MRG-D5000, a flagship G-SHOCK timepiece featuring a screwless, multi-component structure made with blue sapphire crystal and limited to only 20 pieces worldwide.
- Casio developed a specialized, screwless Multi-Guard structure to protect the brittle sapphire material from impact, requiring such precision that only one person at Yamagata Casio, the company's 'mother factory,' can currently perform the assembly.
- The timepiece is water-resistant to 200 meters and solar-powered, sharing durability features with the MRG-B5000SA-2, limited to 500 pieces, and the GMW-B5000SB, which features blue sapphire stones set at four points on the bezel.
- While makers like Hublot and Richard Mille utilize sapphire in high-end watches, Casio defies convention by applying this material to its shock-resistant collection, consistent with the brand's 'Breaking Ground' philosophy since 1996.
- Each of the 20 limited-edition units features an individual serial number engraved on the screw-lock case back, while the design incorporates Gallium Tough Solar technology to ensure durability and efficiency under intense light.
