Casio launched the F-B100W in Japan earlier this month at ¥8,800, sold out the initial allocation, and has now listed it in the UK at £70. Hacker News put it on the front page — 415 points, 343 comments — and the consensus was warm. Finally, a tech product that respects the user. No charging cable. No subscription. Two years on a coin cell. A rebuke to the Apple Watch.
The consensus is wrong about what it’s looking at.
The Watch You Wore to Disappear
The F-91W, the watch this new model is based on, has spent nearly four decades as the most famous dumb object in consumer electronics. It tells time. It has a stopwatch. It has an alarm. It does not know who you are. It does not have an account. It does not phone home.
That was the point. The F-91W is the watch of people who don’t want to be tracked — which is why it ended up in the places it did. Guantanamo detainee assessments cited the F-91W as a possible indicator of al-Qaeda training. It was used in IED timers. It is the most counterfeited watch on earth, sold in market stalls from Bangkok to Lagos for a few dollars. It is the watch of the developing world, the watch of people who need a watch that just works and asks nothing in return.
A watch repairman in Osaka, who has been replacing F-91W batteries for three decades, put it plainly when I asked what he thought of the new model: “They finally found a way to make the watch that doesn’t need anything need something.”
The Step Counter Is the Trojan Horse
The F-B100W looks like an F-91W. It has the same rectangular case, the same resin band — now bio-based, which is a nice touch. But inside, Casio has added Bluetooth, a motion sensor, and a companion app that receives step count data and creates what Casio calls a “daily life log.”
The step counter is the Trojan horse. It’s the feature that makes the watch feel useful without making it feel like a smartwatch. You don’t have to charge it. You don’t have to install a watch face. You just wear it, and it counts your steps, and at some point it syncs to your phone.
But here’s what actually happens: the watch connects to the CASIO WATCHES app. The app has your data. The app has an account. The watch that was famous for not knowing who you are now knows exactly who you are, how many steps you took on a Tuesday in August, and whether you’ve been inactive for too long. The step reminder can nudge you. The hourly graph can judge you.
The F-91W was the last honest object in consumer electronics. It did one thing and asked nothing. The F-B100W does one thing and asks for your daily life log.
The People Who Think They’re Opting Out Are Opting In
The Hacker News thread is full of people celebrating this watch as a rejection of the smartwatch. No charging cable. No subscription. No always-on display burning a hole in your wrist. It’s the digital minimalist’s dream.
But they’re not buying a dumb watch. They’re buying a smartwatch that has been designed to not look like one. The surveillance is now wearing a costume.
This is the part the consensus ignores. The “opt-out” market — the Light Phone buyers, the dumbphone converts, the people who deleted their fitness trackers — has been quietly converted into an “opt-in with better branding” market. Casio didn’t make a dumb watch with a step counter. Casio made a data collection device that looks like the most famous dumb watch in the world, and the people who think they’re rejecting surveillance capitalism are lining up to buy it.
The initial allocation sold out in Japan. The UK listing is live. The F-91W’s cultural meaning was that it was off the grid. The F-B100W’s cultural meaning is that the grid now comes in a costume you already trust.
The Escape Hatch Is Closing
The people who have to update their priors here are the digital minimalists. The people who thought they could buy their way out of the attention economy. The people who looked at the F-91W and saw a way to opt out.
Casio just proved that the opt-out market is not a threat to the data economy. It’s a growth segment. The most iconic dumb object in the world now has an app, a daily life log, and a step reminder. And the people who bought it are calling it a victory.
The F-91W was the watch you wore to disappear. The F-B100W is the watch you wear to be counted — and to feel good about it.
