Product Information

There are faces a little like this – and I do want to particularly praise the new Artist face in watchOS 7 for being totally left-field in a great way – but they mostly still feel like they're playing it too safe.

We used the oxygen sensor on the Apple Watch in tandem with a medical pulse oximeter to check the accuracy of Apple's sensor. The Watch also protects your hearing, being able to warn you if the ambient volume in your location exceeds safe levels. View image in fullscreen The blood oxygen saturation measurements require you to be still with your arm flat on a table for 15 seconds for reliable readings.The S6 also allows for improved screen brightness—the display still features a maximum brightness level of 1,000 nits, but it's brighter in ambient mode when you look down at your wrist. The new S6 processor in the Series 6 is clearly very fast – everything in watchOS is extremely smooth and responsive. This feature has been around, but it triggered much quicker on this new model, as did the auto-unlock feature for Mac. Each device comes with a 12-month warranty so you can purchase your refurbished Apple Watch with a piece of mind.

The standout feature here is a new sensor that can measure the oxygen saturation of your blood, also known as SpO2. Masimo CEO Joe Kiani took advantage of an interview to slam Apple's implementation of pulse oximetry in the Apple Watch, and confirm that there have not been recent settlement talks.To measure it you have to manually activate it on the Series 6 and stay still with your wrist on a table for 15 seconds.

Apple also sent a matching Atlantic Blue Braided Solo Loop band in size 4, which fits perfectly on my wrist. The Solo Loop is made of liquid silicone rubber, while the Braided version is made of 100 percent post-consumer recycled yarn that is braided around a thin silicone thread. The Apple Watch 6 is more a refinement on the Apple Watch Series 5 that came before it than anything groundbreaking.For more precise metrics as you move, the new always-on altimeter continuously tracks your elevation changes in real time, indoors and out.
