Casio says a screwless, multi-component case and bezel structure is designed to protect the brittle material while retaining G-SHOCK shock resistance. Announced regional allocations and prices differ, and the U.S. interest-registration campaign does not guarantee a chance to buy.
What makes the MRG-D5000 Blue Sapphire different?
Casio announced the MRG-D5000 on October 1, 2026, describing it as the first G-SHOCK to achieve a shock-resistant structure using blue-sapphire-crystal components. The bezel is entirely blue sapphire crystal, rather than a conventional metal bezel decorated with a few sapphire accents. Casio also describes sapphire components as difficult to process and vulnerable to cracking around stress points.

To address that challenge, Casio says its Multi-Guard Structure divides the case and bezel into multiple components assembled without screws that could create cracking points. The company says it analyzed the forces transmitted to sapphire during impact and designed the structure to protect the material. Those are manufacturer engineering claims; the published materials do not provide independent impact-test results. Casio’s global product page and its U.S. Blue Rose campaign page describe the construction.
The U.S. campaign compares the case-and-bezel assembly to kigumi, a traditional Japanese timber-frame construction method. It also says the dial lettering includes pure 24k gold, while the dial’s brick pattern refers to the original G-SHOCK motif. These details add to the design story, but the central distinction remains the sapphire bezel and the structure developed around it.

What are the MRG-D5000’s specifications?
Casio’s global product page lists the following specifications. They are manufacturer-published figures, not independent test findings. Source: Casio global product page.

- The product video shows "fluorine elastomer band", but this product is a composite band (resin x fine resin with metal parts embedded). It also features a double locking one-push tri-fold clasp with an extension mechanism that allows you to easily adjust the band when wearing a wetsuit
- G-SHOCK "Frogman" series analog display model with ISO standard 200 m submersible waterproofing to support underwater missions
- Dive mode / Tide graph mode to support diving activities: Dive mode to show diving time and surface rest time. Tide graph mode displays tide information anywhere and current time in that city. Analog display of useful functions for diving activities
- Bluetooth Radio Solar: Support Bluetooth, standard radio wave time correction. Equipped with tough solar, it is stable to drive various functions
- Smartphone Link: Dedicated app allows you to easily set tide data around 3000 locations around the world in the app. You can also check the dive logs on your smartphone and enjoy the data measured on the watch side
How many are being made, and how are regional allocations described?
Casio says the edition totals 20 watches worldwide. The announced regional figures describe separate allocations, not competing global totals:

The regional announcements do not account for the remaining pieces, so they should not be read as a complete breakdown of where all 20 watches will be offered.

How much does the MRG-D5000 Blue Sapphire cost?
Published figures are region-specific and are not a single universal retail price. Casio Japan lists a suggested retail price of ¥11,000,000, including tax. Casio America states a value of $80,000 per U.S. piece. The Japanese figure is a tax-included suggested price; the U.S. release calls its figure a value.

Does U.S. registration guarantee a chance to purchase?
No. The U.S. Blue Rose campaign invites people to register interest, but Casio says availability, eligibility, the selection process, and the purchase window are subject to final official terms. Registration does not guarantee selection or purchase. Check the official U.S. campaign page for current information rather than treating registration as a reservation.

- Directly descended from the first-ever G-SHOCK , the GMW-BZ5000 carries on the evolution of function and material in a transformative, unprecedented design
- They kept the iconic form of the original G-SHOCK, while developing a new structure that extends the case all the way to the lugs to even further mitigate shock transmission
How does it differ from Casio’s other sapphire-themed G-SHOCKs?
Casio’s announcements also mention two other models with sapphire elements, but their construction is distinct from the MRG-D5000:
