Looking to get a smartwatch just to mirror notifications to your wrist, measure daily activity, and monitor vitals? There's no reason to shell out hundreds of dollars towards a Wear OS smartwatch; there are dozens of great budget smartwatches that do a lot of the same tasks for a lot less cash.
My favorite is the CMF Watch 3 Pro. The Nothing-owned sub-brand is doing incredible things with its products lately, and the Watch 3 Pro has all the things you need in a smartwatch: it's stylish, has a bright AMOLED panel, tracks 130 workouts, and you'll only need to charge it once a week. In short, if you need a full-fledged smartwatch in under $100, this is the only one to get — and it's selling for just $61 as part of Prime Day.

There's no doubt that the CMF Watch 3 Pro is the best budget smartwatch today. There really isn't anything missing on this model, and if you want a full-fledged smartwatch that doesn't look like a budget model, this is the obvious choice. View Deal
✅Recommended if: You need the best smartwatch under $100.
❌Skip this deal if: You want Wear OS. Honestly, I don't see the utility of Wear OS when you need to shell out at least thrice as much to get a decent smartwatch.
I don't have any negatives to point out with the CMF Watch 3 Pro. I used the smartwatch when it launched, and it has a stylish design that belies its price tag. You even get good color options, and that just adds to its uniqueness.
The best part is that it runs RTOS, a lightweight OS that does a good job with the basics: mirroring notifications, monitoring activity, and so on. You don't get Spotify integration or Google Wallet, but if you just want a good-looking smartwatch that excels at the essentials, the Watch 3 Pro is more than good enough.
I also like that the smartwatch lasts over a week on average, and this is a huge plus point over my Pixel Watch 4. On the whole, I think the Watch 3 Pro is the best sub-$100 smartwatch available today, and it's selling for just $61 as part of Prime Day.
