Apple Watch Series 6: Better health and more

The Apple Watch Series 6 is the first to offer a blood oxygen sensor. Like the Series 5 before it, the model also has an electrical heart sensor and always-on display. The latter has been "enhanced" for this year. The Series 6 also includes a fresh dual-core S6 SiP.

As the current flagship, the Series 6 is also the only Apple Watch to come in stainless steel, titanium, and Hermès. There are also Series 6 aluminum model exclusives, blue and (PRODUCT)RED. Finally, Series 6 is the only Apple Watch to include a U1 chip. First introduced on the iPhone 11 series, the chip offers improved spatial awareness and accuracy than Bluetooth LE and Wi-Fi.

Who should buy the Apple Watch Series 6

If you're looking for the latest and greatest Apple Watch, the Series 6 is the choice for you. It's the one with the most features and styles. It's two biggest features, the blood oxygen monitor and electrical heart sensor, take wellness to new levels.

Apple Watch SE: Much is the same

With the Apple Watch SE, you still get many of the same features found on the Series 6 but lack the entry-level Series 3. These include 32GB storage, a bigger display, fall detection, international emergency calling, noise monitoring, support for Family Setup, compass, always-on altimeter, Digital Crown with haptic feedback, second-generation speaker, and mic, a ceramic and sapphire crystal back.
