Casio has introduced the MR-G MRG-D5000, a new MR-G flagship with a full sapphire exterior and 64 titanium inner case. The piece explains how the project, begun in 2016, took about 10 years and required abandoning G-SHOCK’s usual shock-absorbing logic in favor of a tightly fitted, multi-part structure.

Why it matters (interpretation): This shows Casio pushing G-SHOCK’s materials and engineering into unusual territory for the brand. The full-sapphire construction also signals how far MR-G is being positioned as a halo line rather than a conventional tough-watch platform.
