Apple's latest smartwatch, the Apple Watch Series 6, gives us almost every feature one could ask for in a fitness tracker while reasserting Apple Watch's position as the most fun, connected, and complete smartwatch experience.

To be fair, the Apple Watch Series 5 also held those distinctions in its time. You could argue the same going for annual releases farther back in the Apple Watch's history. But with the Series 6 addition of native sleep tracking and blood oxygen measurements to complement the already solid fitness foundation, there isn't much more you could ask for in a fitness tracker, or smartwatch, at this point. So, to sweeten the deal, Apple finally gave us some fun colors to keep our eyes from wandering. And at the company's recent fall event, Apple also introduced the less-expensive Apple Watch SE.
