I really liked the CMF BY NOTHING Watch 3 Pro. It has a good design, the screen looks great, and the battery lasts for several days. It accurately tracks heart rate and sleep, and the GPS works perfectly. Plus, you can make calls via Bluetooth without any problems. A very good option for the price.

The CMF by Nothing Watch 3 Pro exceeded all my expectations! The sleek dark grey finish looks modern and premium, and the display is bright and smooth. It’s packed with features you’d only expect from much more expensive smartwatches. Bluetooth calling works flawlessly and the AI assistance is surprisingly helpful. I really love the Energy Score, which gives a clear picture of how ready I am for the day based on sleep and activity — super motivating! Heart rate tracking, sleep insights, and GPS are all accurate, and having 130+ sports modes is perfect for fitness lovers like me. It pairs seamlessly with both Android and iOS, and the battery life lasts noticeably longer than other watches I’ve tried. Plus, the IP68 water resistance gives peace of mind for workouts and everyday use. Overall, this watch delivers premium performance at a great price. If you’re looking for a stylish, powerful, and health-focused smartwatch — this is it! Highly recommend! 👌⌚

The watch itself is actually really nice. it feels well-built, comfortable fit to wear all day, and looks great on the wrist. For the price, I think it's a solid value in terms of hardware and overall design. The item works fine with the Nothing App, and my workouts show up correctly in both that app and Apple Health. However, the Exercise ring in the Apple Fitness app doesn’t update, even though the workouts meet all the usual criteria. Permissions are set, and other activity like walking is tracked with no issues. If you’re someone who relies on closing your Apple Fitness rings, this might be a dealbreaker. I really hope they fix this in a future update, because the watch itself is great otherwise and definitely worth the money.

So I am coming to this watch from an absolutely ancient Apple Watch 2. The battery on that finally bit the bullet and wouldn't charge anymore. Not wanting to spend the 200+ dollars on a new lower end Apple Watch, I decided to take the chance on this one after reading reviews and doing some research. First in terms of looks - This looks fantastic. The watch faces are modern and there are so many options - from more minimal to hyper functional - displaying most of the metrics you would want to see in a smart watch/fitness tracker. I got the dark grey version and it is very clean. There is minimal branding with small text displaying "CMF by Nothing" on the rim around the watch face, but it is barely noticeable. The screen is bright, and I always have mine set on adaptive brightness. I haven't had any issues seeing the screen during a bright day yet. The biggest plus for me is battery life! This thing will not die! The biggest issue I had with the Apple Watch was the battery life. Mine would die near the end of the day, even when the battery wasn't cooked from age. I had to constantly have it on the charge at the end of the day and never used its sleep tracking because the watch would be dead in the morning if I did. This definitely does not have that problem. I've worn this watch 3 days in a row without a charge, and even with pretty frequent use/checking it was still at 60ish percent. I usually charge it by putting it on the charger while I'm getting ready for work in the morning. It will go from 80ish percent to 95+ in the time I'm getting ready. I'm looking at the battery life right now - it is 2:30 in the afternoon and I've had the watch on me since I charged this morning around 6:30 - 95% battery life! In terms of tracking I can't speak much to the accuracy of the workout tracking, as I haven't really approached it with a hyper analytical eye. To me it seems pretty accurate. Sleep tracking seems pretty good, maybe a few minutes off, but that is negligible for my use case. Heart rate sensor seems pretty good, and in that case I was able to actually test it against another device made just for heart rate tracking, and it was only a few beats off, so pretty good there. In terms of using the device I've found it to be a pretty intuitive and easy to use smart watch. Swipe gestures to move around menus, it's very responsive, and the haptics are satisfying. Turning the crown control knob to scroll through menus has a very satisfying buzz at certain increments. It shows my notifications and allows for customization of what notifications come through. I have not used it to take phone calls on the watch itself - still prefer doing that on my actual phone. The only thing I did change about the watch is swapping out the wrist band for a more elastic nylon sport band - I've found silicon bands get a bit stuffy on my wrist and I like breathability of the nylon bands more. I also added a screen protector to the watch face to help prevent scratching. I have this watch connected to an IPhone 17 base, and have had no issues with connectivity or health tracking. You use install the Nothing app and connect the watch via bluetooth to the phone and app. My IPhone health app still shows the daily health metrics from the watch, and I haven't had any issues so far with errors or missing data. All in all, if you are looking for a more budget friendly smart watch or fitness tracker. I would definitely recommend this. If you are looking for a very fitness oriented smart device, this might not fit the bill.

I’ve been using this watch for about one week, and honestly it’s one of the best value smartwatches I’ve tried. The screen is bright and sharp, the battery easily lasts several days, and the interface feels smoother than I expected at this price. The health tracking seems accurate enough for daily use, and the watch face options are surprisingly good. My only complaint is that some notifications can feel a bit delayed, but nothing deal-breaking. For the price, this thing punches way above its weight.
