October Prime Day is almost here -- again. Amazon's annual sale is now semi-annual, with the next one taking place tomorrow. This event is officially called Prime Big Deal Days and lasts for two days.
We can expect Amazon to cut 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.

Apple Watch Series 10 42mm for $329 Save $70 Nina Raemont/ZDNET Current price: $329
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 Apple debuted last week, 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. But if you want to score even steeper deals on the device, you might want to wait until tomorrow's October Prime Day, when the watch's price could go lower. Still, 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
Google Pixel Watch 3 for $211 Save $11 Kyle Kucharski/ZDNET Current price: $239
Original price: $250 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. Show more View now at Amazon View now at Best Buy
