As expected, Apple has unveiled the next model of Apple Watch — the Apple Watch Series 6 — in some flashy new colors, as well as a less-expensive alternative, the Apple Watch SE. As with other recent Apple Watch updates, the Series 6 is focused primarily on adding new health monitoring features, like blood oxygen monitoring, as well as personal customization options, while the Apple Watch SE offers a faster, newer alternative for those looking to spend a bit less. Both can now work without being paired to an iPhone via Apple’s new Family setup feature.

Powered by Apple’s new S6 processor, the Series 6 has a dual-core processor based on the company’s A13 Bionic chip. Along with a faster processor, we have an improved always-on display that’s two times brighter than the Series 5. Rounding out the new hardware is an always-on altimeter.

All this upgraded hardware powers announced features like the Blood Oxygen app. This lets users measure their blood oxygen saturation in just 15 seconds and takes readings periodically throughout your waking and sleeping life. All of this is aimed at keeping track of respiratory and cardiac health, as with asthma symptoms and potential heart problems, for example. Apple’s also partnered to help develop three new research studies, including early onset warning for COVID-19 infection.
