October Prime Day is here -- again. Amazon's annual sale is now semi-annual, and this one runs through Oct. 8. This event is officially called Prime Big Deal Days and lasts for two days.
Amazon typically cuts prices on its company-owned brands, such as Kindle, Ring, and Alexa devices, during this sales event. But more retailers, including Apple, Samsung, Oura, Google, and Garmin, also slash prices on their smartwatches and health trackers to participate. This makes October Prime Day a great opportunity to buy a wishlist item you've been putting off or complete your holiday shopping early.

I'm rounding up some of the best smartwatch and fitness tracker deals on sale during October Prime Day. I'm only including products I have either tested myself or that a ZDNET colleague has tested and recommended, like Apple, Samsung, and Google's top watches and a Galaxy Ring, too. Because I know readers don't have time for random product mentions -- and neither do I.
Best Prime Day smartwatch and fitness tracker deals 2025
Apple Watch Series 10 42mm for $279 Save $120 Nina Raemont/ZDNET Current price: $279
Original price: $399 One of the best Apple Watches you can buy right now isn't from Apple's 2025 smartwatch lineup. It's a great time to buy a Series 10. That's because many of the updates coming to newer Apple Watch models, including the Series 11, Ultra 3, and SE 3, also arrive through software updates available on Series 9 and later. This includes Sleep Scores and Hypertension Detection. Between Series 9 and Series 10, I'd recommend the 10 thanks to its slimmer build that's more comfortable for exercise and sleep. The Series 10 gets several of the same upgrades the Series 11 receives, with the only exception being a longer battery life. If you don't use your watch around the clock or you are on top of charging ahead of your smartwatch dying, this is a great watch to buy right now. Also: Which Apple Watch should you buy? I tested every model, and here's which is best for you You'll get 18 hours of battery life and fast-charging with the Series 10 watch. At $279, this is an attractive deal I'd recommend to anyone who doesn't need the newest smartwatch but still wants an equally capable device. Show more View now at Amazon
