The Pixel Watch 3, 4, and 5 are now getting a free upgrade

  • A free update is rolling out to the Pixel Watch 3, 4, and 5
  • It adds blood pressure and insulin resistance trends with monthly reports
  • Sleep breathing quality metrics are being introduced too

The best health and fitness wearables are racing to pack as many features as possible into their small form factors, and the three most recent Pixel Watch models — the Pixel Watch 3, Pixel Watch 4, and Pixel Watch 5 — are now getting a major upgrade.

As announced by Google, the free update rolling out now to devices will let users monitor blood pressure trends, sleep breathing metrics, and (something the Apple Watch doesn't have yet) insulin resistance trends.

When it comes to blood pressure and insulin resistance, these aren't instant clinical readings — these smartwatches aren't quite advanced enough for that yet — but longer-term patterns, with assessments popping up once a month.

We knew these features were coming too, because they were announced alongside the Pixel Watch 5 unveiling back in August. What wasn't clear was exactly when the features would land, and now we know.

Lots and lots of data

Google says the insulin resistance trend model has been trained on more than a trillion data points gathered from over 5 million users, while the blood pressure model was built with billions of minutes of raw heart and movement data.

With the sleep breathing quality trends feature, you'll get a report each morning on how your breathing varied over the night. This can help you assess overall sleep quality and figure out the best routine and environment for optimal sleep.

Meanwhile, Pixel Watch 4 and 5 models are also getting Breathing Emergency Detection in select European markets (including France, Germany, Ireland, and the UK). This can spot dangerous drops in oxygen saturation and even place a call to the emergency services.

If you're a Fitbit Air user rather than a Pixel Watch user, you'll get blood pressure and insulin resistance trends on your device "later this year," but you'll need a Google Health Premium subscription to access them, which isn't the case with the Pixel Watches.

Save up to 60% on lightweight down jackets from top-quality brands — here are the deals I'd buy

Lightweight down jackets really start to come into their own in the fall. These jackets pack up small and light, and deliver a surprising amount of cosiness for their bulk and weight. They're also great for layering, if you need a little extra protection against the elements.

A number of big outdoor retailers are running deals events right now, with some particularly good discounts on down (and synthetic down) jackets. I've rounded up my top recommendations below — including a number of my favorite brands from my time spent reviewing outdoors kit.

Some of these are pretty major discounts, so it stands to reason they're selling quickly. I've tried to stick to options where there's still a good range of sizes left, but if you're in the mood for some digging around, there are more excellent down jacket deals (with limited stock and sizes) available on each retailer's site. Pick one up now and you'll thank me when the cold weather really sets in.

Garmin fans could soon get ‘muscle oxygen’ readings in future devices

  • Garmin may have bought a fitness company aimed at serious athletes
  • The purchase could add ‘muscle oxygen’ stats to future Garmin products
  • The acquisition has not yet been officially confirmed

The best Garmin devices can do a lot, but there are a few ways they fall short right now. But if a new rumor is correct, Garmin fans could expect to see an interesting new feature for dedicated athletes in future products.

That idea comes from the5krunner, which recently published a report claiming that Garmin has quietly snapped up specialist fitness firm Moxy Monitor, with that impression supposedly confirmed by “a source with direct knowledge of the transaction.”

Moxy Monitor makes muscle oxygen (SmO2) sensors that are used by elite athletes to help them train more effectively. It’s a market that Garmin has apparently been considering entering, with the company filing a patent for an algorithm to measure SmO2 data earlier this year, the 5krunner says.

The report adds that a response by Moxy Monitor’s founder to the outlet’s questions “implicitly confirms the deal.” That’s because Moxy Monitor’s founder directed questions towards Garmin rather than his own company’s press office. Garmin itself has made no comment on the rumored acquisition.

Keeping up with rivals

If you’re a high-level athlete, the revelation of Garmin’s rumored purchase might be an exciting one. If it proves to be accurate, future Garmin wearables might be able to integrate SmO2 measurements and help serious sportspeople improve their performance.

As the5krunner points out, the deal could also lead to Garmin releasing new devices. Since you can’t take SmO2 readings from your wrist and instead need to use a near-infrared spectroscopy sensor, the5krunner says that new hardware would be required if Garmin were to put Moxy Monitor’s tech to good use.

And the report points out that Garmin competitor Whoop has patented its own SmO2 strap. That means that Garmin’s purchase of Moxy Monitor gives it a way to keep up with its rivals in this area without having to build an entirely new system from scratch.

Garmin products can already read SmO2 data from third-party straps, and that will likely to continue to be refined with Moxy Monitor on board. That might be the most immediate change we see, with new hardware further out on the horizon.

Whatever the outcome, anyone wanting to get more serious fitness metrics from their Garmin devices might just get a boost if this acquisition turns out to be the real deal. But with Garmin not confirming anything for now, we’ll likely have to wait for confirmation before knowing exactly how this could play out.

Amazfit's new solar-powered AMOLED smartwatch aims to rival Garmin

  • Amazfit has unveiled the T-Rex Dual Solar smartwatch
  • It offers solar charging on an AMOLED watch — a feat not even Garmin has managed
  • As well as charging from the front, the innovative back plate allows the wearer to invert the watch for maximum light absorption

In a world in which most smartwatches now have the same features and similar specs, it's always nice to see something innovative. The Amazfit T-Rex line is a range of rugged adventure-focused smartwatches that are generally — like almost all of Amazfit's products — great value alternatives to more expensive wearables such as the best Garmin watches.

Despite focusing on solar charging, as seen on some top-tier Garmin watches such as the Fenix 9 Pro, the T-Rex Dual Solar brings innovation all of its own. Amazfit's newest smartwatch not only provides battery-lengthening solar charging from the front, but also a secondary, more efficient solar charging plate on the back of the watch. With enough sunlight, this back plate can reportedly revive a completely flat battery. That means if you're out of power, you could invert the watch and wear it inside-out, or leave it on a rock with the back plate facing the sun, to bring it back to life.

Amazfit says that "for those who adventure at the edge of the map, solar offers something more: a way to bring a completely depleted watch back to life using sunlight when traditional power isn’t available, helping users regain access to essential functions like maps and route information."

However, the most interesting bit is that Amazfit has finally cracked what Garmin has not been able to, as yet: bring solar charging to an AMOLED watch. The Amazfit Dual Solar, as its name suggests, charges from both sides, even though it's got a bright AMOLED screen, as long as you're in conditions of 50,000 lux or more for three hours or more. Without exception, Solar charging Garmin watches uses lower-power memory-in-pixel displays in conjunction with Garmin's Power Glass solar charging tech.

Sara Webster Wylie, VP of Global Marketing at Amazfit, says: “With T-Rex Dual Solar, we didn’t want users to have to choose between the bright, premium display they want every day and the battery endurance they need outdoors. Bringing AMOLED and solar together for the first time lets us deliver both.”

Other specs & pricing

In normal conditions, the watch packs up to 25 days of battery life, extended up to 35 days in optimal solar conditions, and 41 hours of use in 'accurate GPS mode'. A flashlight with red and white modes is built into the titanium casing, while its sapphire crystal screen is capable of up to 3,000 nits of brightness.

With full color preloaded maps (including ski maps), intelligent route planning with turn-by-turn directions and Apple Watch Ultra-style waypoints, and LiveShare (Amazfit's equivalent of Garmin's LiveTrack location-sharing feature), it's certainly a powerhouse of a watch.

Unusually for Amazfit, it's also very expensive, priced at $649.99 in the US. Other regions' pricing is TBC, but that's around £500 / AU$900. Having seen what Amazfit can do with budget devices such as its five-star Amazfit Active 3 Premium, I'm excited to get my hands on a high-end model.

What shoes do marathon winners wear? These 7 pairs of running shoes have all graced the podium at the world's top races

We're gearing up for the second wave of major marathons this year: runners will be heading for the start line in Berlin at the end of the week (27 September), with the Chicago marathon following on 11 October and New York rounding out the season on 2 November.

Perhaps you're wondering what kind of footwear is propelling elite athletes to these kinds of times? I've hunted out the shoes worn by a selection of marathon winners, and rounded up the results below.

The Adidas Adios range crops up time and time again. Sabastian Sawe and Yomif Kejelcha both sprinted to stunning sub-2 hour success at the 2026 London marathon while wearing Adidas Adizero Adios Pro Evo 3 shoes (currently sold out in the US, but a restock is coming in the UK on 24 September.) Sawe wore Adidas Adios Pro Evo 2 to take the gold at the Berlin 2025 marathon, as did Benson Kipruto for his 2025 New York win.

Hot on Kipruto's heels in Berlin 2025 was Alexander Mutiso Munyao, wearing the Adidas Adizero Adios Pro 4. Incidentally, women's champ Rosemary Wanjiru was also wearing Adios Pro 4. In Chicago 2025, Hawi Feysa took the gold in the women's race wearing Adidas Adios Pro Evo 1.

Nike's winning line is the Alphafly. Jacob Kiplimo won the 2025 Chicago marathon in Nike Alphafly 3 — also the running shoe of choice of record-breaker Eliud Kipchoge.

It's not all about Adidas and Nike, though. John Korir has won two Boston marathons in a row while wearing prototype versions of the Asics MetaSpeed Sky, and Sharon Lokedi wore Under Armour Veliciti Elite 3 to defend her crown at Boston 2026. Hellen Obiri took the women's crown at the 2025 New York marathon in On LightSpray Cloudboom Strike — particularly notable for their laceless, 'spray-on' style.

If you're a keen runner and find yourself gripped by marathon fever, perhaps these are some models worth considering for your next long-distance race. But a couple of important caveats, before we start: First, if you're already in training for one of the upcoming marathons, you definitely don't want to be switching up your footwear in the run-up to the event. Second, these shoes are aimed at experienced long-distance runners; if you're not at that stage yet, head to our general best running shoe roundup for more beginner- and intermediate-friendly recommendations.

The Apple Watch 12 just got its first-ever discount at Amazon — see why Apple calls it an ‘ultimate device for a healthy life’

Apple unveiled the Apple Watch Series 12 earlier this month, and it's now officially available to order. While we normally have to wait for holiday sales like Prime Day and Black Friday to score a discount on new Apple devices, Amazon has surprised us with a first-time price cut.

• Shop more daily deals at Amazon

The retailer has the GPS-only Apple Watch Series 12 on sale for $389.99 (was $399) thanks to a rare $10 discount on the Olive Sport Band. That's the best and only deal we've seen on the smartwatch that doesn't require a trade-in.

The Apple Watch Series 12 is touted as the 'ultimate device for a healthy life' thanks to new features like Apple's advanced health sensors, which Apple claims are the most accurate heart rate sensing in a wearable.

6 fitness trackers that do something different — including the viral retro Casio with hidden depths, and a tracker with a 400-day battery

Today's best smartwatches are ultra-capable, feature-packed powerhouses. But is it just me, or are they all starting to feel kinda samey? Casio recently made headlines with its delightfully retro F-B100W, which takes your classic, rubbery, blocky Casio watch and adds in step-counting features. That sent me off on a hunt for other smartwatches and fitness trackers that do something a bit different, and I was not disappointed with the results. I've rounded up my favorites below.

There's the new-out Huawei Watch D3, which looks like your standard, modern smartwatch, but has a secret, in-built blood pressure cuff. For those who prefer a traditional watch aesthetic, there are the Garmin Instinct Crossover and Withings Scanwatch 2, both of which have smartwatch features but also mechanical hands. Neither is especially new, but both have maintained popularity by their seamless blending of digital and analog.

Finally, a couple of especially intriguing options from outside the big watch brands. The Jaye band is an ultra-minimalist smartwatch that displays only the most important notifications on its tiny screen to minimize distractions. And then there's the LightInk, which can run for an absurd 400 days on a single charge. Such a lengthy runtime is achieved by adding solar charging, swapping your average vibrant AMOLED display for a low-energy, monochrome e-ink one, and stripping the smart features right, right back. It's open source, so with the aid of a 3D printer and a few basic components, anyone could own one.

A camera in a toothbrush? Dyson tells us why it combined 'WiFi, AI, intelligent sensing and fluid dynamics with a highly engineered brushing experience' to create the Dyson Camerajet

The Dyson Camerajet arrived 10 years after online rumours emerged that Dyson had filed a patent application for an electric toothbrush with water jet. True to form, it has surpassed the rumours with a toothbrush that goes one step beyond the norm and is packed with innovation. Having trialled it a week prior to launch, I was among the first journalists to give the Dyson Camerajet a hands-on review.

As the only smart electric toothbrush and water flosser with a built-in camera, the CameraJet uses imaging, machine learning and precision fluid dynamics to identify gaps between teeth and deliver a jet of mouthrinse. The CameraJet has received much attention since its launch, with many praising Dyson for pushing the boundaries with new innovation in oral health, and others questioning its price, reporting faults online, and asking whether we need a camera in a toothbrush at all. But for a brand that revolutionised the vacuum with cyclonic suction, restyled the hair dryer and pioneered bladeless fan technology, the Dyson CameraJet was never going to be an obvious product.

Back in May 2026, I visited Dyson’s factory and global HQ in Singapore to take a first look at the Dyson CameraJet. I went behind the scenes in Dyson’s oral health care labs where six years of research, development and engineering for the CameraJet had been taking place and spoke to Rich Bacon, head of product development at Dyson, to find out what makes the CameraJet so unique. I also asked him about the potential security implications of having a smart camera in the bathroom, and how Dyson hopes to improve our oral health.

Why now?

When I first saw the CameraJet I immediately wanted to know why Dyson is branching into attempting to make one of the best electric toothbrushes and why now?

The Dyson team said it likes to start with a problem people experience every day and ask whether they can solve it better through engineering. “Oral care is an area where many people want to improve their routines, but often struggle with consistency, technique, or understanding how effectively they're brushing,” Bacon explained. “Dyson research shows 9 in 10 people do not floss as regularly as they should, reinforcing the need for a solution that helps target the gaps between teeth as part of an everyday routine.

“The technology is now at a point where we can combine WiFi, AI, intelligent sensing and fluid dynamics with a highly engineered brushing experience, making this the right time to bring the product to market.”

By combining two devices – a toothbrush and water flosser – in one, the CameraJet has the potential to save us time in our daily routines and also help us brush for the recommended time. “In our research we found that a lot of people brush for 45 seconds, but the optimum time is for two minutes, or ideally three,’ says Bacon. ‘When I’m using this device myself for three minutes, it’s much more convenient than having separate devices to clean your teeth.”

What excites Bacon most about the CameraJet is its sophisticated engineering combined with a simple user experience. “There’s a huge amount of technology working behind the scenes here from the camera and machine learning, to its Gap Optical Targeting and precision fluid dynamics,” he says. But the user doesn't need to think about any of that. As engineers, that's always our goal: solving complex problems in a way that feels effortless for the person using the product.”

Bacon believes that this technology has the potential to make oral care more consistent and personalised. “Many people brush their teeth in exactly the same way every day without really knowing if they are cleaning effectively, and many are not flossing as regularly as they should. Dyson CameraJet brings brushing, precision-flossing and mouth-rinsing to your routine to target the gaps between teeth where plaque can build up.”

Privacy included

But in an age of AI, the internet of things and relentless data collection, having a camera in your bathroom is a natural cause for concern. For Dyson, privacy was also a key consideration, however. Bacon reassures me that the camera is only active during live viewing or auto-jetting; no images are recorded or stored on the product or in the cloud, and images remain private to the user.

“We take privacy very seriously,’ he says. “The MyDyson app is a great companion piece and comes with unique cleaning insights such as location coverage. Through the app, you can also access guided cleaning, coverage mapping and personalised feedback so you have a better understanding of where you are cleaning well and where you may be missing.”

The app is a closed ecosystem, but could it one day become a broader health-data platform, similar to how people use Oura or Apple Health? “The app has been designed as a platform that can evolve over time, and the immediate focus is on useful, evidence-led insights that help people understand their brushing and interdental cleaning habits,” says Bacon. “There is an opportunity to help make those behaviours easier to see, understand and improve. Any future information or guidance would need to be grounded in robust evidence and developed responsibly, but our ambition is to empower users with helpful, accurate feedback about their oral care. We're always exploring how technology can help people get more from our products.”

Teething problems

Since its launch, there have been reports on Reddit of a small number of early production batches malfunctioning, so TechRadar reached out to Dyson for comment.

‘We are aware that a small number of early batches of Dyson CameraJet products may have experienced a component issue,’ says a spokesperson for Dyson.

‘We are isolating those batches and are taking all the necessary steps to support our customers. We have had a very positive reaction to the new Dyson CameraJet and are experiencing strong demand globally and we are seeing some shortages of supply as we are in the process of scaling up production.’

Whether or not you’re tempted to try a toothbrush with a built-in camera and smart app, it’s exciting to see Dyson engineers paving a way with new innovations in oral health. And for that, I think we have a reason to smile.

The Huawei Watch Fit 5 Pro is made from titanium, looks like an Apple Watch, performs really well against a top-tier Garmin watch — and is currently under £200

While all eyes this week were on the launch of the Apple Watch Series 12, there are plenty of other wearables out there receiving tempting discounts that might turn your head. As we slowly march towards peak deals season, culminating in Black Friday, we're likely to see discounts on watches from Samsung, Garmin, Huawei and more.

Today it's Huawei's turn, with the excellent Huawei Watch Fit 5 Pro. Right now, you can get the Huawei Watch Fit 5 Pro discounted from £249.99 to just £199 at Amazon, in its black color. Orange and white options are available, but the discounts aren't quite as good. Check out the deal in full below:

Today's best Huawei Watch Fit 5 Pro deal

Save over £50 on the Huawei Watch Fit 5 Pro in its black color. It's a great alternative to an Apple Watch: in our Huawei Watch Fit 5 Pro review, we said it "succeeds, from a hardware perspective, in every way that matters". Its high-quality titanium case, accurate metrics, and a week's worth of battery life seal the deal. View Deal

Why get this deal?

I personally tested this watch, running around the streets of Paris and comparing its stats to a top-tier Garmin Fenix 8 Pro on the other wrist, which costs around £1,000 (or did at the time). The Fenix 8 Pro is the best Garmin had to offer (or was, until the Garmin Fenix 9 Pro arrived), with its Elevate V5 premium heart rate sensor. Comparing the two watches, their respective average heart rate measurements differed by just 1bpm.

I can confirm that it's an accurate watch; the titanium casing looks and feels great to wear, and it's ideal for runners in particular due to a rich feature set. It's got virtual pacers with snappy animations to keep your runs on time, which is perfect for training through your winter arc, ready to hit some races in Spring.

I gave the watch 4.5 stars out of 5 in my Huawei Watch Fit 5 Pro review. It's a great value package, and it's now cheaper than ever, making it easy to recommend.

It's also easily mistaken for an Apple Watch at first glance, so if you're after a Series 12 but don't want to pay launch prices, this is an ideal buy over the Apple Watch SE 3. The only sticking point is that it doesn't work with third-party apps like Spotify and WhatsApp as well as other smartwatches do, and you have to sideload apps via Huawei's AppGallery.

A street photographer took Dyson's camera toothbrush on a photo walk — and the lo-fi images are otherworldly

  • Instagram creator All Gear No Skill has used Dyson's CameraJet toothbrush to shoot street photos
  • The $499.99 / £419.99 / AU$799 brush uses a 100k-pixel (0.1MP) camera to find the gaps between your teeth
  • Shots were grabbed by screenshotting the live feed in the MyDyson app

You may have heard the phrase "the best camera is the one you have with you", but what if that's a toothbrush? Instagram creator All Gear No Skill (@allthegearnoskill) has taken Dyson's new CameraJet out of the bathroom and onto the streets, using its tiny built-in camera to capture a series of gloriously odd street photos.

Launched at the start of September, the CameraJet is Dyson's first foray into oral care, and it costs a jaw-clenching $499.99 / £419.99 / AU$799. Tucked just below the brush head is a 100k-pixel macro camera that feeds a machine learning system Dyson calls Gap Optical Targeting. It analyzes at 28fps to spot the gaps between your teeth, then fires a cone-shaped jet of mouth rinse at each one, so you're effectively flossing while you brush.

The same camera doubles as a dental endoscope, streaming a live view of your molars to the MyDyson app (which, as TechRadar writer Emily Peck found in her Dyson CameraJet review, can be a little more revealing than you might like).

Point, shoot, rinse, repeat

That live view is the key to "taking photos" with the toothbrush. Dyson says the CameraJet doesn't save images on the brush or in the cloud, and there's no capture button in the app, so the process is refreshingly low-tech. You point the brush head at your subject, watch the feed on your phone, and take a screenshot when the composition looks right. It's like a $500 / AU$800 remote viewfinder with bristles.

As you'd expect from a sensor designed to peer at incisors from a few millimeters away, the results won't have anyone trading in their Leica: the macro lens bends everything into a fisheye-style bubble, 100k pixels works out to a mere 0.1MP resolution, and the colors and white balance wander all over the place, lending the shots a strange, almost infrared look. For me, the photos instantly brought to mind the otherworldly, hallucinatory AI-driven image generation from a few years ago: think Will Smith eating spaghetti.

The CameraJet surely won't be the last unlikely gadget to get this treatment, either, because cameras are turning up in all sorts of devices that have nothing to do with photography. Your car may have several for parking and driver assistance, robot vacuums use them to dodge kids' toys and charging cables, and some smart fridges and ovens will let you peek at what's inside via your phone. Not to mention robot lawn mowers and VR headsets.

Plenty of these offer a live feed in a companion app, so there's a house full of accidental point-and-shoots out there waiting for someone with a sense of humor. Personally, I can't wait for the first portrait series shot entirely on a fridge.
