Casio America has unveiled the MRGD5000 Blue Sapphire, a new MR-G luxury timepiece that is the first G-SHOCK watch to achieve a shock-resistant structure using components made with blue sapphire crystal. The watch uses Casio's proprietary MR-G Multi-Guard Structure, with a bezel and case assembled from multiple separate components without the screws that can cause sapphire crystal to crack, and it will be available in a limited edition of only 20 pieces worldwide. Six of the 20 MRGD5000 Blue Sapphire timepieces, valued at $80,000 each, will arrive in the U.S. with staggered availability between December 2026 and June 2027. Casio also announced two additional blue sapphire crystal timepieces: the MRGB5000SA, a 500-piece limited edition MR-G priced at $6,600, and the GMWB5000SB, a full-metal G-SHOCK priced at $770, both available beginning in November 2026 at gshock.com, the G-SHOCK Soho Store, and select retailers. The MRGD5000 also features blue sapphire crystal set into the screw-lock case back, engraved with an individual serial number for each of the 20 limited-edition pieces, and a module incorporating Gallium Tough Solar.
