Now is the perfect time to upgrade your smartwatch, with our favorite smartwatch, the Apple Watch Series 10, on sale. The 42mm model is currently priced at $370, down from $399 in Jet Black, while the 46mm model is on sale for $399, down from $429, available in both Jet Black and Silver Aluminum. Released just a month ago alongside new products like the AirPods 4 and iPhone 16, the Series 10 Watch earned a 90 in our review for features like its thinner frame, bigger screens, and onboard speaker for music and podcasts. The battery life of this smartwatch is also slightly improved compared to its predecessor, and it now includes sleep apnea monitoring for tracking sleep patterns. Notably, the Series 10 Watch does not have a Blood Oxygen app as Apple faces copyright litigation.
