We here in the Gadget Lab (and millions of people around the world) agree: If you have an iPhone, the Apple Watch is the best wearable to go with it. But which version should you buy? Apple is expected to announce the Series 8 next week along with a new Pro watch. And the company is still selling the Series 7 and the SE, as well as the aging Series 3 for now. But the much-loved Series 5 and 6 have gotten the boot (though you may still find them on sale). All these watches look pretty similar and share a rotating stable of features. Here, we break down which one is best for you, and whether older models are worth the price.

Be sure to check out our other buying guides, like our Best iPad, Best Smartwatch, and Best iPhone roundups.

Updated September 2022: We removed the Series 3 and added information on possible upcoming watches.
