Casio Unveils $80,000 Blue Sapphire G-Shock, Its Most Expensive Watch Ever

A watch that costs eight times what a Rolex costs
The MRG-D5000 represents Casio's dramatic shift from affordable sports watches to ultra-luxury positioning.

So Casio made a watch that costs eighty thousand dollars. That's the headline. But why does that matter? Isn't Casio just chasing luxury like every other brand?

Mimi

Not quite. G-Shock built its entire identity on being cheap and tough. This watch is the opposite of that DNA. It's saying the brand is big enough to mean something at every price point.

Luke

But we should be careful here. The source material tells us the watch exists and costs eighty thousand dollars. It tells us it's made of blue sapphire. What it doesn't tell us is how many they're making, whether they've actually sold any, or what the actual demand is.

Mimi

Fair. We know the material is real and the price is real. We know it costs eight times what a Submariner costs. That comparison alone is striking because it puts Casio in conversation with Rolex.

Mark

Does the sapphire actually justify the price, or is it just marketing?

Mimi

The source material suggests it's a genuine engineering challenge—growing the sapphire, shaping it, assembling it so the watch still functions. That's not nothing. But whether consumers see it as worth eighty thousand dollars is a different question.

Luke

Exactly. We can report that Casio made this choice and priced it this way. We cannot report that it will succeed or that the market accepts it. That's still being written.

Mark

So this is Casio taking a real risk.

Mimi

Yes. They're betting that G-Shock is a strong enough brand to stretch upward. That's either brilliant or it's a very expensive mistake.

Luke

And we won't know which for a while.

  • Casio has priced its new G-Shock at $80,000 — eight times the cost of a Rolex Submariner — a figure that stops the watch world cold.
  • The entire case, bezel, and crystal are made from blue sapphire, a technically demanding material choice that goes far beyond cosmetic luxury.
  • The launch creates real tension: G-Shock's loyal base was built on affordability and toughness, and an ultra-luxury pivot risks fracturing that identity.
  • Casio is framing the release not as a novelty but as a strategic declaration — a signal that G-Shock intends to compete at the very summit of the watch market.
  • The critical unknown is whether luxury collectors will accept a brand historically associated with construction sites and backpacks as a legitimate prestige object.

For decades, the G-Shock name has meant something specific: resilience without pretense, durability at a democratic price. Now Casio has introduced the MRG-D5000 'Blue Rose Project' — an $80,000 watch constructed entirely from blue sapphire — and in doing so, asked a quiet but profound question about whether a brand's identity is fixed or merely a starting point. The move places G-Shock in direct conversation with heritage luxury watchmakers, not as an imitator, but as a challenger staking new ground.

Casio has released an $80,000 G-Shock. The model, called the MRG-D5000 and nicknamed the 'Blue Rose Project,' is constructed entirely from blue sapphire — case, bezel, crystal, all of it — making it both the most expensive G-Shock ever made and a genuine feat of materials engineering.

The price demands context. A Rolex Submariner, one of the most sought-after mechanical watches on earth, sells for around ten thousand dollars. The new Casio costs eight times that. G-Shock built its reputation on the opposite premise: tough, affordable, unpretentious watches you could wear anywhere without worry. That identity was the brand's foundation for decades.

Blue sapphire changes the equation entirely. The material is prized for its hardness and clarity, but using it as the primary structural element of a watch case is rare and technically demanding — lab-grown, precision-shaped, and carefully assembled. This is not a marketing gesture. It represents a real engineering commitment and a deliberate move toward a different kind of consumer.

What Casio is signaling is intent. The MRG-D5000 is not a limited-edition stunt or a celebrity collaboration. It is a statement that G-Shock believes it can occupy the uppermost tier of watchmaking, competing with brands that have spent generations earning their luxury credentials.

Whether collectors will accept that repositioning is the open question. The 'Blue Rose Project' name suggests Casio is framing this as something aspirational — even romantic. But an $80,000 G-Shock asks buyers to fundamentally reconsider what the name means: not a tool, but an object of desire. Casio has placed its bet. The market will decide whether the brand's identity is elastic enough to reach that high.

Casio has released a watch that costs eighty thousand dollars. It is a G-Shock, the brand that built its reputation on affordable, durable sports watches for everyday wear. The model is called the MRG-D5000, and it carries the nickname "Blue Rose Project." What makes it extraordinary is not just the price but the material: the entire watch—case, crystal, bezel, all of it—is constructed from blue sapphire.

For context, a Rolex Submariner, one of the most coveted mechanical watches in the world, typically sells for around ten thousand dollars. The new Casio costs eight times that amount. The comparison alone signals something significant about how the company is positioning itself. G-Shock has spent decades as the watch you buy when you want something tough and cheap, something you can throw in a backpack or wear to a construction site without worrying about damage. The brand's identity was built on that premise: durability without pretense, function without luxury markup.

The shift to blue sapphire changes the entire equation. Sapphire crystal is prized in watchmaking for its hardness and optical clarity, but using it as the primary structural material for an entire watch case is rare and technically demanding. The stone must be grown in a lab, shaped with precision, and assembled in a way that maintains the watch's integrity. This is not a marketing flourish. The material choice represents a genuine engineering challenge and a commitment to a different market segment entirely.

The MRG-D5000 appears to be Casio's deliberate entry into ultra-luxury watchmaking. This is not a limited edition novelty or a one-off collaboration. It is a statement of intent. The company is signaling that it believes G-Shock can occupy space at the very top of the watch market, competing not with mid-range sports watches but with heritage luxury brands that have spent generations building their credentials.

What remains to be seen is whether collectors and luxury watch enthusiasts will accept this positioning. G-Shock's strength has always been its accessibility and its no-nonsense approach to design. The brand has earned trust through consistency and value. An eighty-thousand-dollar G-Shock asks consumers to recalibrate their understanding of what the name means. It asks them to see the watch not as a tool but as an object of desire, not as something you use but as something you own.

The "Blue Rose Project" name suggests Casio is aware of this transition and is framing it as something aspirational, even romantic. Whether that framing will resonate with the watch-buying public remains an open question. What is certain is that Casio has made a clear bet: that the G-Shock brand is strong enough to stretch upward, that sapphire and precision engineering can justify a price point that would have seemed absurd just a few years ago, and that there is a market willing to pay it.
