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.

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.

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.

Samsung unveiled its Galaxy Watch 8 earlier this summer. The device comes with a day’s worth of battery, further AI integrations thanks to Gemini, an AI running feature that I’d recommend to anyone embarking on their first or next race, and an Antioxidant Index to measure nutrients in the skin. Wearing the watch was comfortable, and it comes with a flat build and a bright screen with 3,000 nits.

The deal only subtracts $35 off the smartwatch, but for Android users looking for a new smartwatch, this could be an attractive buy.

Google just unveiled its fourth-generation Pixel Watch, which comes with significant upgrades to the smartwatch. Luckily, some of the announced upgrades, like a revamped Fitbit Premium app that’s coming to all Google-owned devices, will hit the Pixel Watch 3. If you’re in the Android ecosystem and looking for a high quality and nearly-new watch, this could be the deal for you. 

The smartwatch comes equipped with a 24-hour battery life, so you can work, exercise, and sleep with it before dies on you. It’s also packed with AI features, like Gemini, for advanced queries and task management. While not the steepest discount, this — in the champagne gold colorway — is still marginally better than buying at full-price.

The Apple Watch SE is a great smartwatch for first-time buyers and for kids. If you’re in the Apple ecosystem and have wanted to try out a smartwatch but don’t necessarily want to shell out several hundred dollars, the SE is a great option. While it lacks some of the bells and whistles of the Series 10 and Ultra models, it still includes all of the essentials, like the ability to make calls, send texts, and use Siri, as well as health features like heart rate monitoring and Fall and Crash Detection.

Prime Big Deals Day takes place from Oct. 7 through Oct. 8 this year. During the sale, the retailer cuts prices on thousands of products (and many products from brands it owns, like Kindle, Alexa, Ring, and more). 

Are smartwatches really cheaper on Prime Day? 

You might not see the same substantial deals you’ll see on Amazon-owned devices, like Kindle or Alexa devices, on smartwatches. Still, retailers like Apple, Samsung, and Google, just debuted their new lineup of products, and as demand rises for the newer generations of smartwatches, the demand for older generations declines. This is great for budget-conscious consumers not interested in the newest and shiniest devices. 

How did we choose these Prime Day deals?

ZDNET only writes about deals we want to buy — devices and products we desire, need, or would recommend. Our experts looked for deals that were at least 20% off (or are hardly ever on sale), using established price comparison tools and trackers to determine whether the deal is actually on sale and how frequently it drops. 

We also looked over customer reviews to find out what matters to real people who already own and use the deals we’re recommending. Our recommendations may also be based on our own testing — in addition to extensive research and comparison shopping. The goal is to deliver the most accurate advice to help you shop smarter.
