A GPS watch from Scotland landed on the front page of Hacker News the day before yesterday—not because of a faster chip or a more accurate heart rate sensor, but because it lets you swap the battery and screen, charge over USB-C, and gives you an open API.
An “Outdated” Product Idea Gets 206 Upvotes
Recently, a GPS smartwatch called UNA received 206 upvotes on Hacker News and rose to the front page. In HN terms, that score isn’t a breakout event, but it’s enough to show how strongly the tech community resonates with it.
The core reason isn’t how impressive its hardware specs are. In fact, UNA’s spec sheet looks almost spartan in the 2026 smartwatch market: dual-band GPS, a six-axis accelerometer, a barometric altimeter, all-day heart-rate monitoring, 10-day battery life, a 280mAh battery, and IP68 water resistance. Even three years ago, those specs wouldn’t have been top-tier.
Three things set it apart:
Repairable design. The battery and screen can be replaced with a single screwdriver—an extremely rare design in wearables.
USB-C charging. Not a magnetic cable, not a proprietary dock, but the same USB-C cable you use with your phone.
An open developer platform. There’s an SDK and an API, so developers can build custom apps and watch faces.
After a decade of cutthroat competition in the smartwatch industry, these three selling points sound almost primitive—but they hit the industry’s deepest pain points.
The Industry Is Walking Into a Dead End
Consider a few simple numbers: according to Counterpoint, the global smartwatch market shipped more than 160 million units in 2025. Apple Watch held about 30% share, while Garmin, Huawei, Samsung, and Xiaomi split the rest. At the same time, the average lifespan of these devices is getting shorter.
The reason isn’t that the hardware has stopped working. It’s “non-failure obsolescence”:
Battery degradation. Smartwatch batteries usually show noticeable degradation after 18–24 months, but on most products—from Apple Watch Ultra to Galaxy Watch—the battery isn’t user-replaceable. Replacing the battery means replacing the whole device.
Broken screens. Watches are among the electronics most likely to get bumped or dropped, and screen repairs often cost close to—or even more than—the value of the device.
Software drop-off. watchOS gets roughly four to five years of update support, and Android watches often get less. A device with fully working hardware is forced into retirement because it can’t get the next version of the system.
The common outcome of these three situations: a watch that is otherwise intact is discarded because its repairability is zero. This isn’t a quality problem. It’s a byproduct of design philosophy.
Apple Watch’s design choices are completely understandable—chasing extreme water resistance, a thinner body, better sensor integration—but the price is that the whole device becomes a “non-removable capsule.” When the battery’s life is exhausted, what you get isn’t a replacement opportunity; it’s a recycling code.
This is a microcosm of the global e-waste problem. According to the UN Global E-waste Monitor, the world generated about 74 million tonnes of e-waste in 2025. Although wearables are small individually, they are among the fastest-growing categories of all. The EU’s Right to Repair legislation has been advancing for years, and only by 2026 will it gradually cover smartphones and tablets. Wearables remain a regulatory blind spot.
From Framework to UNA: The Business Case for Going Against the Tide
You might say this is a “nostalgia route” that doesn’t work commercially. But Framework’s experience is worth considering.
When Framework launched its first repairable modular laptop in 2021, the mainstream view was that consumers wouldn’t pay a premium for repairability—it was a tiny geek niche. Four years later, Framework hasn’t just survived; its annual shipments have continued to grow, and in 2025 it reached a considerable share of the high-end Linux laptop market in North America. It proved that a serious enough “anti-industry” product can find a loyal, highly sticky user base in the shadow of mainstream brands.
UNA’s design logic is strikingly similar to Framework’s:
It isn’t trying to build a “better Apple Watch”; it’s trying to build a different one. UNA doesn’t compete with mainstream brands on sensor count, chip process node, or screen resolution. It chose a narrow but painful enough niche: people who need a GPS sports watch that can genuinely last for years and that they can maintain themselves.
The 10-day battery life is the result of a design choice, not an engineering limit. When a brand doesn’t need to squeeze body thickness to the absolute limit, it can use a larger battery and doesn’t have to trade “charge once a day” for millimeter-level thinness. And 10-day battery life is a strong enough selling point on its own.
USB-C isn’t a feature; it’s a stance. At a time when Apple Watch sticks with a proprietary magnetic charger—now in its fifth generation, with five different specifications—and Garmin uses its own charging clip, USB-C charging becomes a user need that mainstream brands have deliberately ignored. Its significance goes beyond convenience: it means the product has no intention of creating lock-in through accessories.
Developer Platform: Differentiation or an Extensibility Trap?
Another dimension worth watching with UNA is its developer SDK.
The smartwatch industry’s history with openness isn’t pretty. Pebble was an early pioneer of openness, and Samsung’s Tizen watches tried it too, but neither managed to build a large enough app ecosystem. Apple Watch’s choice was not to open up native apps to third-party developers, allowing only limited widgets and watch-face extensions. Garmin has its own Connect IQ platform, but its developer experience has a so-so reputation in developer communities.
UNA’s choice—an open SDK that lets developers build custom activities, tools, and watch faces—is strategically a way to “use community power to cover the product’s weaknesses.” For a startup team, it’s impossible to fund a software ecosystem team of thousands like Apple does, so trading openness for ecosystem contributions is the most pragmatic choice.
The risk here is just as obvious: maintaining an SDK isn’t cheap over the long run. When Pebble shut down in 2016, what people mourned most was its creative app ecosystem that never became a business. UNA needs to prove it can live long enough for developers to feel their time investment was worth it.
Why Chinese Smartwatch Brands Should Pay Attention
To be honest, UNA won’t become an Apple Watch competitor, and in the short term it won’t pose a real threat to Garmin. But its arrival offers three signals worth learning from for Chinese smartwatch makers:
First, hardware going global needs a differentiated “value anchor.” When Chinese smartwatch brands (Huami, Huawei, Xiaomi, Amazfit, TicWatch) go overseas, they tend to benchmark specs against Apple Watch—more accurate heart rate, longer battery life, higher water resistance. But in mature Western markets, the marginal returns from spec wars are shrinking. UNA’s case shows that “sustainability” and “right to repair” are becoming value labels that some overseas consumers are willing to pay for. This isn’t just a marketing-messaging issue; it’s something product design needs to answer.
Second, modular design may be the right path for midrange sports watches. The high end has Garmin Fenix and Apple Watch Ultra; the low end has Xiaomi bands; and competition in the middle of the GPS sports watch market is intensifying. The trio of “repairable + long battery life + open platform” offers a positioning play different from “competing on sensors and screens.”
Third, “Right to Repair” isn’t an issue unique to Europe and the U.S. Chinese consumers’ awareness of repairable hardware is waking up. Although Framework hasn’t officially launched in China, it has considerable buzz among tech enthusiasts. If a domestic brand were willing to launch a USB-C-charging, battery-swappable smartwatch in the RMB 300–500 price range, it might well find a market.
UNA is a hardware product swimming against the current. Its significance isn’t that its specs beat someone else’s; it’s that it asks again a question the industry has deliberately avoided: who should decide how long a smartwatch lasts?
In an industry rhythm where an Apple Watch gets replaced after two years and a Garmin battery can’t hold up after three, UNA’s chosen path—repairable, open, restrained, sustainable—is never going to be the fastest growth curve. But Framework and Fairphone have already proved that products like this can survive—and keep surviving.
The only question is: when its first users need a battery replacement—probably in the summer of 2028—will UNA still be selling that screwdriver? That is the one test every “anti-industry” hardware product eventually has to face.
