You’d think a guy with a net worth hovering around $150 billion would have something crazy on his wrist. Maybe a Patek Philippe Grandmaster Chime or a custom Rolex encrusted with conflict-free diamonds. But no. If you look closely at the wrist of Microsoft co-founder Bill Gates during his TED talks or casual interviews, you’ll see something surprisingly humble. It's a Casio. Specifically, it is usually the Casio Duro Marlin MDV-106-1A1V.
He wears a watch that costs less than a decent steak dinner in Manhattan. It’s wild.
The Bill Gates watch Casio choice isn't just about telling time; it’s a massive signal about his philosophy on wealth and utility. While other tech titans like Jeff Bezos have been spotted with high-end pieces (Bezos famously wears a Ulysse Nardin Dual Time), Gates sticks to the quartz movement of a mass-produced Japanese tool watch. It’s reliable. It works. It doesn't need a winding machine or a five-figure insurance policy. Honestly, there is something deeply relatable about a billionaire who doesn't want to worry about scratching his watch while he’s out saving the world from polio.
The Specific Model: What Exactly Is the Bill Gates Watch Casio?
The most famous "Gates" watch is the Casio Duro MDV-106.
It’s a diver’s watch. For the uninitiated, "Duro" is Spanish for "tough" or "hard," and it lives up to the name. This thing is water-resistant up to 200 meters. That is technically deep enough for actual scuba diving, though most people just use it to track how long their pasta has been boiling.
The watch features a 44mm stainless steel case, which is actually quite large for most wrists, but Gates pulls it off because he’s relatively tall. It has a black dial, a unidirectional rotating bezel (the clicky ring on top), and a simple date window at the 3 o'clock mark. The most iconic part of the original MDV-106 is the little Marlin fish logo on the dial. Interestingly, Casio actually lost the rights to use that Marlin logo in some regions recently, making the "Gates version" with the fish a bit of a collector's item among watch nerds who enjoy irony.
He has also been seen wearing even cheaper models. At a Politico event, he famously flashed a Casio W214H-1AV, which is a digital sports watch that retails for about $20.
Think about that for a second. Twenty bucks.
Why the Duro?
The Duro is widely considered by watch enthusiasts—people who usually talk about "horology" and "in-house movements"—as one of the best value-for-money watches ever made. You get a screw-down crown and a screw-lock back. These are features usually reserved for watches in the $200-$500 range.

Gates isn't just being cheap. He’s being efficient. He’s choosing a tool that performs its primary function (tracking time) with a 99.9% accuracy rate thanks to its quartz crystal.
The "Quiet Luxury" That Isn't Luxury at All
There’s this trend lately called "quiet luxury." You know the vibe—billionaires wearing $600 plain white T-shirts that look like they came from a three-pack at Target. But Gates isn't doing that. He’s doing "No Luxury."
By wearing a Bill Gates watch Casio, he bypasses the entire game of status signaling. It’s the ultimate power move. When you are one of the most influential humans in history, you don't need a gold watch to tell people you’re important. In fact, wearing a $50 watch makes you seem more grounded, even if you’re flying in a private jet to get to your next foundation meeting.
It’s about "Frugality Theater" to some extent, but mostly it's just practical.
I’ve seen plenty of analysts try to break down his psyche through his wristwear. Some say it's about his public image for the Bill & Melinda Gates Foundation. If you’re asking governments to donate billions to global health, you probably shouldn't be wearing a watch that costs more than a village hospital. It’s good optics. But if you track Gates back to the 80s and 90s, he’s never really been a "bling" guy. He’s a software engineer at heart. He likes things that are logical.
Comparing the Duro to Other "Billionaire Watches"
The tech world is split into two camps: the "Watch Guys" and the "Function Guys."
- The Watch Guys: Think Larry Ellison of Oracle. He’s been seen with a Richard Mille, which can cost $200,000 or more. These are mechanical marvels, basically wearable engines.
- The Function Guys: This is where the Bill Gates watch Casio fits. Tim Cook obviously wears an Apple Watch (company man). Mark Zuckerberg used to wear nothing at all, though he's recently started sporting some higher-end pieces as he leans into a "style" era.
The Duro stands alone because it’s not even "smart." It’s "dumb" tech that works forever. The battery lasts about three years. If it breaks, you don't repair it; you just buy another one. Though, knowing Casio, it probably won't break.
The Cult of the Casio Duro
The "Gates Effect" actually drove sales of this specific model. Amazon often sees spikes in search terms for "Bill Gates Casio" whenever a new high-profile interview drops.

Watch collectors love it because it’s a "safe" watch. You can wear it to the beach, get it covered in sand, and not care. It’s also a "strap monster." If you take off the somewhat cheap-feeling rubber strap it comes with and put it on a $15 nylon NATO strap, it suddenly looks like an Omega Seamaster from a distance.
Is It Just an Act?
Is Bill Gates secretly hiding a collection of rare vintage Patek Philippes in a temperature-controlled vault in his $130 million mansion, "Xanadu 2.0"?
Probably not.
People who have worked closely with him often remark on his lack of interest in "stuff." He spends his money on land, books, and massive infrastructure projects. The watch is a tool.
There is a famous story from an interview where he was asked about the watch. He laughed and said it was a $10 watch. He was actually underestimating the price—or maybe he got a great deal. Regardless, the point was clear: he doesn't care.
The Technical Specs (For the Nerds)
If you're looking to buy the Bill Gates watch Casio, here is what you are actually getting. It’s not just a cheap piece of plastic.
- Case Material: Stainless Steel. This gives it a decent weight. It doesn't feel like a toy.
- Movement: Japanese Quartz. It’s remarkably accurate, losing maybe a few seconds a month.
- Lume: The hands glow in the dark, though to be honest, Casio’s lume isn't as bright as a Seiko.
- Size: 44mm diameter, 48mm lug-to-lug. It’s a chunky boy. If you have very small wrists, it might look like you're wearing a wall clock.
- The Bezel: 120-click unidirectional. It feels surprisingly crisp.
It’s basically the Toyota Corolla of watches. It’s not fast, it’s not flashy, but it will still be running when the sun expands and swallows the Earth.
How to Rock the "Gates Look"
If you want to adopt this vibe, you don't need a billion dollars. You just need about fifty bucks and a lack of ego.

Most people who buy the Duro immediately swap the strap. The "resin" band it comes with is functional but a bit stiff. If you put it on a brown leather strap, it looks like a dress watch. Put it on a "Bond" striped nylon strap, and you're 007 on a budget.
It’s the ultimate "stealth wealth" piece because it proves you have nothing to prove.
Where to Buy It
You can find the MDV-106 at almost any major retailer—Amazon, Walmart, or Target. Because of the logo changes, look for the "Marlin" (the fish) if you want the exact Gates version. The newer version (MDV-107) is the exact same watch but lacks the fish on the dial.
Moving Beyond the Hype
The fascination with the Bill Gates watch Casio says more about us than it does about him. We are obsessed with the idea that the ultra-wealthy are "just like us." When we see him wearing a watch that we can afford, it bridges the gap. It makes the man who revolutionized computing and global philanthropy feel a little more human.
But it’s also a lesson in consumerism. We are constantly told we need the next iPhone, the newest car, or a luxury timepiece to be successful. Gates is a walking (and talking) rebuttal to that idea.
Success is measured by your output, not your accessories.
Actionable Insights for the Aspiring Minimalist:
- Audit your "status" purchases: Are you buying things because they work well, or because of what they say about you?
- Invest in the Duro: If you need a "beater" watch that can survive a hike, a swim, or a board meeting, the MDV-106 is a genuine horological icon.
- Swap the strap: A $10 NATO strap can change the entire aesthetic of a budget watch, making it look ten times more expensive than it is.
- Focus on utility: Like Gates, look for products with a high "utility-to-cost" ratio. Reliability usually trumps luxury in the long run.
