Imagine a smartwatch that doesn’t just hug your wrist to track your health but invites you to tap its side with your fingertip for a deeper dive into your vitals. That’s the pitch for Huawei’s Watch 5, a sleek wearable that’s making waves in Europe and the UK with its innovative “multi-sensing X-TAP technology.” It’s a fancy name for a side-mounted sensor array that promises to measure everything from your heart’s electrical signals to your blood oxygen levels in a snap. But while Huawei’s latest gadget sounds like a health nerd’s dream, it’s not without quirks—and you can’t even buy it in the US.

Smartwatches have long relied on sensors pressed against your wrist to monitor your heart rate, stress, or sleep. The Huawei Watch 5 doesn’t ditch that approach—it’s got the usual wrist-based optical sensors—but it adds a twist: a side-mounted sensor you activate with your fingertip. Huawei calls this X-TAP, and it’s essentially a mini health lab packed into the watch’s edge. It includes an EKG electrode to measure your heart’s electrical activity, an optical sensor for heart rate and blood oxygen (SpO2), and even a pressure sensor to gauge how firmly you’re pressing.

Why the fingertip? It’s a hotspot for accurate readings. Your fingertips are rich with capillaries and have excellent blood flow, which is why medical-grade pulse oximeters—the kind you see in hospitals—often clip onto your finger. Huawei claims this setup delivers a signal quality 10 to 50 times better than traditional wrist sensors. That’s a bold statement, and while independent testing is needed to verify it, the logic tracks. Fingertip-based devices, like the Wellue O2Ring or even those clunky pulse oximeters at your doctor’s office, are known for their precision.

The payoff is speed and scope. The Watch 5 can measure blood oxygen in just 10 seconds—faster than most smartwatches, which often take 15–30 seconds for a spot check. It also powers a “one-tap health glance,” a 60-second scan that delivers a dizzying array of metrics: average heart rate, heart rate variability (HRV), blood oxygen, skin temperature, stress, EKG, arterial stiffness, respiratory overview, and sleep disturbance awareness. If that sounds like a lot, it is. Most of these features were already on the Watch 4, but HRV—a measure of the variation in time between heartbeats, often linked to stress and recovery—is a new addition. Arterial stiffness, which can hint at cardiovascular health, is another standout, though it’s not unique to Huawei (Samsung’s Galaxy Watch series has offered similar metrics).

Here’s where things get murky. The Watch 5’s fingertip sensor is undeniably cool, but its real-world value depends on how often you’ll use it. Unlike wrist-based sensors that work passively in the background, the X-TAP requires you to actively press your finger against the watch. That’s fine for occasional checks, but it’s not as seamless as, say, the continuous heart rate monitoring on an Apple Watch or Fitbit. If you’re someone who loves diving into health data—maybe you’re training for a marathon or managing a chronic condition—this could be a fun tool. For the average user, though, it might feel like overkill, especially since many of these metrics (like SpO2 or HRV) are hard to act on without medical context.

Huawei’s not alone in chasing fingertip tech. The Withings ScanWatch 2, for instance, has an EKG sensor that requires you to touch the watch’s bezel, and Samsung’s Galaxy Watches can measure blood pressure and EKG with a similar finger-on-sensor approach. But Huawei’s decision to cram multiple sensors into one spot is ambitious, and it could set a precedent for future wearables. The question is whether users will embrace the extra step of tapping the watch or stick to wrist-based tracking for convenience.

The Watch 5 isn’t a complete overhaul of its predecessor, the Watch 4. It’s more of a polished evolution with a few shiny upgrades. The display, for starters, is brighter—peaking at 3,000 nits, which puts it on par with high-end watches like the Apple Watch Ultra. It also has slimmer bezels for a more modern look. The watch comes in two sizes: a 42mm model (aimed at smaller wrists) and a 46mm version for those who like a bolder presence. Battery life is solid, with the 42mm lasting up to three days (two with the always-on display) and the 46mm stretching to 4.5 days (three with AOD). That’s better than most Apple Watches but not quite as long as some fitness-focused brands like Garmin.

Huawei’s also thrown in two new gesture controls: a “double slide” (sliding your thumb against your finger) and a “double tap.” These sound like nice additions for navigating the interface, though it’s unclear how intuitive they’ll feel in practice. The watch supports cellular connectivity, so you can leave your phone behind, and it plays nice with both Android and iOS devices—a rarity in a market where Apple and Samsung often lock you into their ecosystems.

Design-wise, the Watch 5 is a looker. The 42mm model comes in stainless steel with color options like beige, gold, white, and green. The 46mm offers black in stainless steel, plus titanium versions in brown, silver, and—Huawei’s proudest flex—a “purple” variant. More on that purple in a moment.

Huawei’s marketing team seems downright giddy about the titanium purple option for the 46mm Watch 5. Titanium is notoriously hard to colorize, often requiring anodization (a process that uses electric currents to create a colored oxide layer). Huawei says it used “advanced methods” involving “oxidation parameter adjustment and hue deviation” to craft an “exact purple with an opaline effect.” They claim this purple has a subtle blue-gray sheen, unlike the “solid, high-saturation purple” you might see elsewhere.

As someone who owns multiple purple phone cases and a lavender keyboard, I was intrigued. But the press photos? They’re a letdown. The “purple” looks more like a muted silver with a faint lilac tint—think the iPhone 14 Pro Max’s Deep Purple, which was about as purple as a cloudy sky. Huawei’s poetic description might resonate in person, but based on images alone, it’s hard to call this a win for purple enthusiasts. If you’re buying the Watch 5 for its bold color statement, you might want to temper your expectations or opt for the green or gold instead.

Here’s the kicker: if you’re in the US, the Watch 5 is off-limits. Huawei’s ongoing trade restrictions, stemming from national security concerns raised by the US government, mean the company can’t sell its devices stateside. You might be able to import one, but that’s a hassle, and you’d likely miss out on full software support or warranty coverage. For Americans, the Watch 5 is a tantalizing glimpse at what could have been—a reminder of Huawei’s knack for pushing boundaries in a market dominated by Apple, Samsung, and Google.

For those in the UK and Europe, the Watch 5 is available for preorder starting May 19, 2025, with an official launch on May 26. It’s priced at £399.99 in the UK and €499.99 in Europe—roughly $550 USD, though currency conversions don’t tell the full story due to taxes and regional pricing. That puts it in the same ballpark as a Galaxy Watch7 or an Apple Watch Series 10, making it a premium option but not outrageously priced for what it offers.

The Huawei Watch 5 is a fascinating mix of innovation and iteration. Its fingertip sensor is a bold move that could inspire other brands to rethink how wearables collect health data. The speedy SpO2 readings and comprehensive health glance are impressive, even if they’re geared more toward data geeks than casual users. Add in a bright display, solid battery life, and cross-platform compatibility, and you’ve got a compelling package—assuming you’re okay with its purple shade being more “meh” than “marvelous.”

But the lack of US availability stings, and the fingertip sensor’s usefulness hinges on how much you value active health checks over passive tracking. If you’re in Europe or the UK and looking for a stylish smartwatch with a unique health twist, the Watch 5 is worth a look. Just don’t expect it to reinvent the wheel—or to be as purple as Huawei claims.
