There is now a G-Shock that costs more than a car. Casio has unveiled the MRG-D5000, the first production G-Shock with an outer case and bezel carved entirely from blue sapphire crystal — more, as Wired put it, than a Patek Philippe or a Porsche Macan. The price is $80,000, the run is limited to 20 watches worldwide, and each one is hand-assembled by a single master technician at Casio’s Yamagata factory, according to Hypebeast. It is, officially, the most expensive G-Shock ever made.
Nine Years to Make Sapphire Survive a Drop
The idea came from G-Shock creator Kikuo Ibe back in 2017, and it’s easy to see why it took nearly a decade. Sapphire is famously scratch-proof — and famously brittle. The one thing a G-Shock is supposed to survive is a drop. As Fratello reports, Casio’s Blue Rose Project team grew sapphire ingots over several months, selected sections for color and transparency, then engineered an interlocking, screwless Multi-Guard structure inspired by traditional Japanese timber joinery. The sapphire pieces lock together like a three-dimensional puzzle, dispersing impact forces with no drill holes or screws to act as weak points. The case had to grow to 16.45mm thick to make it work — and it still keeps 200 meters of water resistance.
The finishing is pure haute horlogerie: a blue PVD brick-pattern dial referencing the original 1983 square G-Shock, lettering in 24-karat gold, and a Grade 5 titanium caseback set with its own sapphire crystal, engraved “Dream Project” alongside the watch’s individual edition number. Even the strap got its own engineering: rather than the sapphire bracelet of early prototypes, the production watch uses a specially developed Dura Soft rubber strap with the same brick pattern and a new titanium clasp — because a sapphire bracelet would be a beautiful nightmare you’d never want to drop. Inside, the module is pure workhorse Casio — Gallium Tough Solar charging, Multi-Band 6 radio-controlled timekeeping, world time across 38 cities, as Hodinkee’s hands-on details.
The $80,000 Flagship Has Two Siblings
The MRG-D5000 doesn’t stand alone — it crowns a three-watch Blue Rose Project lineup. The MRG-B5000SA-2DR pairs blue sapphire inserts with a Cobarion bezel for $6,600 in a 500-piece run, and the full-metal GMW-B5000SB-1A2ER brings sapphire accents to the bezel for $770 with no production limit. All three land in November and December, and all three keep the classic square silhouette.
Buying the flagship won’t be a casual purchase: in Japan it sells by lottery from December 1, and it’s now listed on Casio’s US site, where hopeful buyers must register for eligibility through a “Register for the Opportunity” link, according to G-Central.
Why this matters
In the smartwatch era, watch technology is supposed to get cheaper and faster every year. Casio just proved the opposite is possible: take the humble digital watch — the same 1983 square silhouette that once cost pocket money — and through a decade of materials engineering, make it worth more than most Rolexes. The MRG-D5000 isn’t a gadget you buy; it’s proof that G-Shock’s idea of “toughness” can be translated into sapphire, titanium and gold without losing its soul.
And here’s the part that actually matters for the rest of us: the $770 sibling. Blue sapphire on a G-Shock you can walk into a store and buy in November. The halo watch gets the headlines; the affordable one gets the wrists.
