Apple just announced the all-new Apple Watch Series 6. It has a similar design form factor to Series 5 from last year. But it includes some new sensors that allow it to measure blood oxygen level and improved sleep tracking.

All it takes is 15 seconds to measure the amount of oxygen in your blood. The Series 6 comes with a new S6 processor that is 20 percent faster than previous gen.
Apple is also not including a power adapter for the Series 6 in an effort to reduce carbon footprint.

The display is 2.5 times brighter than the previous-gen as well. Apple Watch Series 6 will be available starting at $399. You can get one starting today. Color options include gray, silver, gold, and blue aluminum finishes and a new Product (RED) version as well.
