What the G-Shock MRG-D5000 Blue Sapphire
The release, the specs, and the engineering problem Casio had to solve to make it.
The G-Shock MRG-D5000 Blue Sapphire is an $80,000 square G-Shock with a bezel and outer case cut from blue sapphire crystal, limited to 20 pieces worldwide. It is the most expensive production G-Shock Casio has ever sold, and deliveries start in December 2026.
Casio announced it on October 1, 2026, to mark 30 years of MR-G, the flagship metal line that launched in 1996. Casio's own product page titles it the MR-G 30th Anniversary MRG-D5000 Blue Sapphire. Only about six of the 20 are reportedly coming to the United States.
The shape is the DW-5000 square everyone knows. What changed is the material. In a phone photo it looks like a translucent resin G-Shock you could buy at the mall, which is going to cause some confused comments on Instagram. The blue parts are machined sapphire sitting over a black DLC-coated titanium core.
Quick specs
Why a sapphire G-Shock was supposed to be impossible
Sapphire is extremely hard and also brittle. It shrugs off scratches, then cracks under a sharp hit, which is the exact test a G-Shock exists to pass. Kikuo Ibe, the engineer who created G-Shock, showed a sapphire square prototype at the brand's 35th anniversary event in New York in 2017. According to launch coverage, it failed Casio's own shock testing and never went to market.
The fix was getting rid of screws. Drilled screw holes create the stress points where sapphire cracks, so Casio split the bezel and case into multiple sapphire components that lock together around the titanium core with no fasteners at all. Casio calls it the Multi-Guard Structure for Sapphire. Press coverage has compared it to kigumi, the Japanese carpentry method of joining wood without nails.
The rest is full MR-G. A Gallium Tough Solar module, Multi Band 6 radio timekeeping, a sapphire crystal with anti-reflective coating, and a screw-lock titanium caseback with more blue sapphire set into it and each piece's serial engraved. The Dura Soft strap carries a brick-pattern texture that matches the dial.
The short version
Casio just made the most expensive G-Shock in its history. Here is how a dealer reads it, as of October 2026.
- $80,000 in the US and ¥11,000,000 including tax in Japan, with 20 pieces worldwide and about six for the US.
- It is the first G-Shock with a case built from sapphire crystal, assembled without screws so the sapphire survives impact.
- Collectors should care because it finishes a project G-Shock's creator first showed in 2017, in a run of 20 numbered pieces.
- Our forecast is that first-year dealer offers land below what a US buyer pays after tax. Buy it to keep.
- The catch: sapphire has no melt value, the strap is rubber, and the lower Japanese price will cap US premiums.
G-Shock MRG-D5000 Blue Sapphire price
Retail in the US and Japan, and the number that actually leaves your account.
The MRG-D5000 retails for $80,000 in the United States and ¥11,000,000 including tax in Japan. Buy it in Los Angeles and $80,000 becomes $87,800 after sales tax.
That takes the record from the 18k solid gold G-D5000-9 Dream Project, which listed at $70,000 in 2019 across 35 pieces. Casio's US site lists the MRG-D5000 with a registration form for a chance to buy, so expect a draw. In Japan, Casio is selling it by lottery.
The Japanese price works out to roughly $69,500 at the exchange rate used in launch coverage. That is more than $10,000 under US retail before tax, and it matters a lot for resale. We come back to it below.

The two cheaper Blue Sapphire models
Casio launched two siblings alongside it. The MRG-B5000SA is $6,600 and limited to 500 pieces. It uses a Grade 5 titanium case with blue ion plating and sets two 2-carat, facet-cut blue sapphire crystals into the top and bottom of the bezel, with the MR-G 30th anniversary mark and a serial number on the caseback.
The GMW-B5000SB is $770. It is a full-metal square with blue sapphire stones set at four points on the bezel. Both are expected in November 2026 through gshock.com, the G-Shock Soho store, and select retailers.

Why collectors should care about the G-Shock MRG-D5000
Four reasons this matters beyond the headline price.
Casio built a G-Shock out of a material that fails the G-Shock test on its own, then made it pass. That engineering story, in 20 numbered pieces, is what collectors are paying for.
It finishes a nine-year storyline
Collectors love an ending. The sapphire square has been a known prototype since Ibe held it up in 2017, and Casio reportedly ran the production effort under the internal name Blue Rose, a nod to a flower that does not grow naturally. The MRG-D5000 is the payoff, and the first production piece of anything tends to be the one people remember.
Twenty pieces is genuinely small
Most limited editions from large brands run into the hundreds. Twenty worldwide, with roughly six for the US, means most serious G-Shock collectors will never see one on a wrist. The gold Dream Project had 35 pieces and only two for the US, and it became the reference point for G-Shock rarity for the next six years.
It puts G-Shock into the materials conversation
Sapphire cases have mostly belonged to Swiss brands like Richard Mille, Hublot and Bell & Ross, on mechanical watches. Putting one on a solar-powered, radio-synced, 200m digital watch rated for shock is a different kind of flex. It tells the high-end collector that Casio's engineering belongs in the same room.
It is a Japanese-made flagship
Casio lists it as made in Japan, and launch coverage reports each piece is assembled by hand at the Yamagata factory. MR-G has spent 30 years being the line where Casio shows off its finishing. This is the furthest it has pushed.
MRG-D5000 vs the gold Dream Project and the cheaper Blue Sapphire models
The four watches a buyer is realistically choosing between.
If you want the record-setter, it is the MRG-D5000. If you want the blue sapphire look on a watch you will wear every day, the $6,600 MRG-B5000SA is the smarter buy for most people.

Specs from Casio and launch coverage. Bracketed cells were unconfirmed as of October 7, 2026.
The gold watch is the obvious comparison, and the differences matter for value. Gold is heavy, recognizable and carries melt value. The MRG-D5000 weighs 121g, looks like resin from across a room, and its material has no scrap value at all. One is a bar of gold shaped like a G-Shock. The other is an engineering trophy.
MRG-D5000 Blue Sapphire resale value, our forecast
What we expect the secondary market to do, and the data behind it.
We expect marketplace asking prices above retail and real dealer offers below it. If you win a US allocation at $80,000, plan to own it, because a first-year sale will most likely lose money after tax.
Nothing has traded. Deliveries begin in December 2026 and the US pieces reportedly arrive on a staggered schedule through June 2027. This forecast is built on the closest precedent we have, and we will update it once real pieces change hands.
MRG-D5000 secondary market forecast
WatchGuys estimates as of October 7, 2026, for a complete set with box, papers and matching serial. No MRG-D5000 has changed hands yet.
Run the math at the middle of our dealer range. A $70,000 offer against an $87,800 purchase leaves a first-year seller in Los Angeles $17,800 short. Asking prices on marketplaces will look exciting. Asking prices are not money.
The gold Dream Project is the precedent
The G-D5000-9 retailed for $70,000. A Hong Kong dealer listed one at HK$880,000, about $113,000, and it was still listed years later. When Phillips offered one in its TOKI auction in November 2024, the published estimate was roughly $26,000 to $51,000. A pre-sale estimate under retail tells you what auction specialists expected bidders to pay, and that was a watch with gold value underneath it.
Three things that cap the upside
The Japanese price comes first. At about $69,500 with tax, any lottery winner in Japan who sells can undercut a US seller and still profit. That puts a lid on US premiums.
Then there is the missing floor. Gold always has a melt price. Sapphire is worth exactly what the next collector will pay, nothing more.
Last is the buyer pool. People willing to spend $90,000 or more on a quartz digital watch are a small group, and many of them entered the same draws you did.
What could push it higher
Twenty pieces, a first-of-its-kind material, the Ibe story and the MR-G 30th anniversary are a strong combination. G-Shock has also started showing up at serious auction houses, with both Phillips and Sotheby's putting the gold Dream Project in front of bidders. Low serials, especially 1/20 and 20/20, will likely carry a premium over the rest. If G-Shock collecting keeps growing the way it has, a clean MRG-D5000 could clear retail in five to ten years. Treat that as a bet.
What we will check when one crosses our counter
The caseback serial against the warranty card first. Then every sapphire edge under a loupe, especially the corners and button guards, since chips on a brittle material do not polish out. We will confirm radio sync and solar charging, look for wear where the rubber strap meets the clasp, and make sure the glass presentation box is complete and uncracked.
Risk flag
If a sapphire bezel component chips, Casio is the only realistic place to replace it, and parts pricing has not been published. Before buying one secondhand, ask for close-up photos of every sapphire edge and confirm the serial matches the papers.

Should you buy the MRG-D5000 Blue Sapphire?
Our position, and who should ignore it.
Buy it if you collect G-Shock seriously, win an allocation, and plan to keep it for years. Everyone else should buy the $6,600 MRG-B5000SA or put the money into a watch with a deep resale market.
Who should buy it
The collector who already owns the MR-G squares, the full-metal GMW-B5000 variants and maybe a Frogman, and wants the one piece that ends the set. If $80,000 is discretionary money and you will wear it, this is the most interesting thing Casio has ever made. Try for a US allocation and enter the Japanese lottery if you have a way to.
Who should look elsewhere
Anyone hoping to flip it. Our numbers say a quick sale loses money. Anyone who wants app connectivity, since Casio's spec sheet for the MRG-D5000 lists no smartphone link while the cheaper MRG-B5000SA has it. And anyone who wants a mechanical movement with decades of resale data at this price. For that money, our Rolex watch market report shows what actually holds value, and if you are thinking of trading in, we will buy your Rolex the same day.
