Apple Watch Series 6 GPS, 40mm Blue Aluminium Case with Deep Navy Sport Band - Regular

Product Information

The watch offers information about this metric to help you interpret your data. It says that most people have a blood oxygen level between 95 and 100 percent. The first time I used this feature, the Series 6 said my blood oxygen saturation level was 99 percent. The second time I took a reading, it was after a three-mile beach run, and I was happy to see my SpO2 level was 100 percent. A subscription is required for Oceanic+. Available on the App Store. Always follow diving protocols, and dive with a companion and have a secondary device. You don't need the Series 6 to take advantage of these features. WatchOS 7 is also available on Apple's Series 3, 4, and 5 watches, as well as the new Watch SE. Apple Watch SE has a water resistance rating of 50 metres under ISO standard 22810:2010. This means that it may be used for shallow-water activities like swimming in a pool or ocean. However, Apple Watch SE should not be used for scuba diving, waterskiing or other activities involving high-velocity water or submersion below shallow depth. Water resistance is not a permanent condition and can diminish overtime. For additional information, see support.apple.com/en-gb/HT205000. But before we get to that, let's just remind ourselves what a blood oxygen (or SPO2) sensor actually does. Firing red and infra-red light under the skin, the diodes on the underside of the Apple Watch 6 can read the color of your blood, and work out from that how much oxygen you're pumping around.

In the box with the watch, Apple includes a charging cable, but you don't get a USB power adapter. Apple says it made this decision to help the environment, and it will have the same impact as eliminating 50,000 cars from the roads. Design Placing the Watch higher up our arm helped with the accuracy (as it’s easier for the sensor to read the pulse through the skin here), but it wasn’t comfortable and fell forwards eventually.

Apple Watch Series 6 Blue (aluminum)

Apple Watch Series 1 has a water resistance rating of IPX7 under IEC standard 60529. Apple Watch Series 1 is splash and water resistant, but submerging it is not recommended. You do need to get the gesture right though, and too often we found that Siri wasn’t in fact listening, which turns you off from using a voice assistant instantly, especially if other people can see you. But... for the most part. According to the Health app on the phone, which records this information, there was a moment when our SPO2 level fell to 88% – was that something to worry about? We assumed that, because it wasn't repeated, it was just an outlier reading, but it was still a little disconcerting to see. The Apple Watch 6 is still a strong contender, which is why it's maintained a place in ours best smartwatch round-up, although it's not as high as it once was.

The international emergency calling feature requires an Apple Watch Ultra 2 (Cellular), Apple Watch Series 9 (GPS + Cellular) or Apple Watch SE (GPS + Cellular) model. For a list of supported countries and regions, see apple.com/uk/watchos/feature-availability. We're not sure why Apple isn't offering those alerts, and it makes it hard to say whether the SPO2 meter is particularly useful as a result.One element we didn’t use much was Walkie-Talkie mode – in the last year, we’ve found that the people we would chat to (while hilariously saying ‘over’ at the end of each sentence) using this method has dropped to the point where we now feel like we’re just going to be irritating by requesting a chat. And therein lies the rub with the new SPO2 sensor on the Apple Watch. On the one hand, it can be comforting to see your blood oxygen level sitting nicely where it should be… but equally, Apple is saying the Apple Watch 6 is categorically not a medical device, and should only be used for your own information (which, it should be noted, most wearables on the market with an SPO2 sensor are stating as well). Charge times are from 0–80% and 0–100% using the included Apple Watch Magnetic Fast Charging USB‑C Cable. Testing conducted by Apple in August 2023 using pre‑production Apple Watch Ultra 2 (GPS + Cellular) paired with iPhone; all devices tested with pre‑release software, Apple Watch Magnetic Fast Charging USB‑C Cable (Model A2515) and Apple 20W USB‑C Power Adapter (Model A2305). Charge time varies with region, settings and environmental factors; actual results will vary.

The watch uses data from the barometric pressure sensor, GPS, and nearby Wi-Fi networks to determine your exact location and update your elevation on the fly. You can also add your elevation as a complication on the watch face. On the outside, the Apple Watch 6 continues with the same design language used in previous models – a rounded, metal body with a square display that curves elegantly into the device itself. However, combined with the ability to take an ECG and monitor your heart's regular output, it's still a comfort, and those with heart conditions would probably still gravitate towards the Watch 6 as a result. Apple Watch 6 fitness Compatible hardware and software required. Not all content available in Spatial Audio with Dolby Atmos.The Series 6 also features Apple's signature digital crown on the top right side. Press this button to return to the watch face; press and hold it to talk to Siri; or turn it to scroll, zoom, or adjust. Apple Watch Ultra 2 has a water resistance rating of 100 metres under ISO standard 22810. It may be used for recreational scuba diving (with compatible third-party app from the App Store) to 40 metres and high-speed water sports. Apple Watch Ultra 2 should not be used for diving below 40 metres. Water resistance is not a permanent condition and can diminish over time. For additional information, see support.apple.com/en‑gb/HT205000. The ECG app and irregular rhythm notification require the latest version of watchOS and iOS, and are not intended for use by people under 22 years old. The ECG app is available on Apple Watch Series 4 or later (not including Apple Watch SE). The irregular rhythm notification is not designed for people who have been previously diagnosed with AF. The wake-up screen is nice, showing you the amount of battery left and the weather for the day – so while it is a limited feature, the elements it does have are well executed.

We want to wear the Watch 6 for everything, though, so it would be great if Apple equipped this device with a way to set up interval training, more easily see laps when you're trying to beat a mile PB, or just step up the Workouts app to encourage those who’ve been training with the Watch for years to go to the next level.In fairness, this must be an incredibly hard feature to get to work well – the Watch has to listen for the specific sound of running water at the same time as detecting a very specific hand motion, so it’s actually quite impressive that it works as often as it does. With all the settings turned off you’ll get comparable battery life to the Apple Watch SE, but with more longevity during workouts or listening to music.
