Over the past five years, smartwatches have transformed into must-have accessories that blend style, health and an array of smart features.

Whether Apple or Android, there’s a smartwatch that fits your lifestyle and budget. If your needs are basic — think exercise, notifications and sleep monitoring — most smartwatches will do. But if you want more advanced tracking, premium models with polished software and health tools, like blood pressure and sleep apnea monitoring, are solid options.

We’ve tested every watch on this list. If you’re looking to make the investment, here are our top picks for the best smartwatches.

Best smartwatch overall: Apple Watch Series 10

The Apple Watch Series 10 takes a winning formula and updates it for the Apple Watch’s 10th birthday. It is slimmer and lighter than earlier Apple Watches, with two new case sizes: 42-millimeter or 46-millimeter. The wide-angle OLED screens make the watch brighter when looking at it off-axis. The LTPO3 technology also brings a ticking second hand to the always-on display.

The Apple Watch Series 10 also comes with sleep apnea notifications, which can detect signs of this potentially dangerous condition over 30 days.

Battery life is still rated for 18 hours, though you can push it to a day and a half with lighter use. The Apple Watch Series 10 now has even faster charging though, which makes up for the battery life somewhat, able to charge to 80% in 30 minutes. Overall, it’s an incredibly polished smartwatch and the best choice for most iPhone owners.

Best Android smartwatch: Google Pixel Watch 3

Google’s Pixel Watch 3 offers one of the most elegant round-screen designs you’ll see on a smartwatch and now comes in two size options to suit more wrists. It also comes with a range of new tools, including AI-generated running workouts, the Morning Brief digest, and more applications for the Daily Readiness Score.

The Pixel Watch 3 is still missing some features you might expect on a Google-branded smartwatch, including Gemini support. Overall, if you’re a runner and want more robust smartwatch features than on a traditional running watch, the Pixel Watch 3 won’t disappoint.

Battery life all-star: OnePlus Watch 3

The $330 OnePlus Watch 3 is a standout smartwatch that outshines other Wear OS contenders with its five-day battery life, sleek design and solid health features. It covers all the essential smartwatch functions while improving on health and fitness tracking by adding more metrics, boosting accuracy and offering deeper workout analysis. Its one-stop wellness check feature measures blood oxygen levels, sleep quality, cardiovascular health and stress levels. The OnePlus Watch 3 is a great choice if your main priority is battery life and durability, but it’s not without a few drawbacks. While its bulky stainless steel design makes it look premium and polished, the 1.5-inch AMOLED screen can easily overpower smaller wrists, and there’s no smaller size available. It also lacks an LTE option, and the ECG feature is disabled in the U.S. and Canada.
