Using the CMF by Nothing Watch Pro has been one of the most frustrating experiences I’ve had in a while, and that’s saying something, given that I’ve tested dozens of smartwatches in the last year. Still, there are some things to like about this cheap 69 dollar smartwatch; A watch which I expect many are considering as a cheap Apple Watch alternative. However, as you will see in this video, based on my systematic testing of this watch, I think many of you will be disappointed with the performance of this first smartwatch of CMF by nothing. At least, that is, if you care about the sports and health tracking of this watch. Outside that, the watch does look and feel quite premium for the price. However, you can judge yourself based on the data I will share in this video.

I was quite excited to test the nothing watch, and I bought two of them to be able to collect a lot of data quickly. However, after connecting them with two of my iPhones, I noticed the first big problem I had with the nothing watch pro: none of the sports and sleep data was syncing to either of my iPhones. I could see it on the watch, but it just wasn’t there on the phone. I’d chosen iPhones since I was hoping to sync my data with Apple Health, but not only was this not happening, the data was not even showing up on the Nothing Watch app itself. I tried a bunch of things, and even contacted their help desk. I tried all their tips, but if this didn’t work, they suggested I go to an offline CMF service center.

So, the sleep stage tracking of the CMF Watch Pro just isn’t very good. I at least would not trust it to tell me anything useful about my stages, except perhaps my total time spent in bed. So, if you want anything more complicated than that, just pick another watch. Overall, I’d give the sleep stage tracking of the CMF Watch Pro, 2 out of 5 stars. So, as you might have guessed by now, with the current firmware and app, I am not very happy with the CMF Watch Pro. First of all, my data is locked in an ecosystem with a poorly performing app, and second, the health and sports data it does provide is more or less useless to me. That being said, more subjectively, I do like the design and simplicity of the CMF Watch Pro. And, for the price, it does feel surprisingly premium. It is kind of chunky, which means that it looks quite big on smaller wrists. So, if you don’t care about the health and sports tracking data, this might still be for you, but if you do, I would steer clear. Therefore, overall, I’d give the health and sports tracking of the CMF by Nothing Watch Pro, 1.5 out of 5 stars.

Manually extracting data from screenshots - that is THE level of madness dividing scientists from us - mere humans. I just love your attitude!

[qwer]

For the manual extract of the data. Kudos!

[victorvansande]

Big respect for the lengts you're willing to go through just to give us scientific and accurate data. Well done, these videos are the best of its kind out here on YouTube! Keep it up man.

THANK YOU ROB! Many of the issues you've reported PLUS MORE on the actual watch portion of their software/hardware have not worked correctly (or at all) since launch, and they've responded to none of the comments that I and many others have listed on their community feedback boards. It's basically a decent looking watch that barely even tells time correctly. As always, GREAT VIDEO!

I have watched Marques Brownlee's review of this watch, and... what a difference. Here we finally get a real review.

[mehboobb]

Really looking forward for your review on CMF Watch Pro 2.

[MrMorton]

I was interested in this watch because of the price but you definitely helped make that decision easier! Thanks for your effort and reveal 🙂

[danielmoksmann]

The first graph at 2:46 made my heart sink. 😄
And the others were even worse! Carl Pei should watch your video.

[bllr]

One of the most underrated YouTube channels. Keep up the great work!

[MorriganJade]

Seeing the many reviews that are done more critically, I can safely say that Nothing has nothing to say.

[Adam-M]

I’ve been waiting for this one!! Thanks for sharing.

[Fremmy]

This has been an anticipated review. Thanks for the hard work Rob!

[JakobDam]

Almost random data generation, unknown data policy without direct access... Life pro tip: Buying 2 dice and call whatever you throw your current heart rate, is cheaper and seems to work just as well as the Nothing Watch Pro.

Big thanks to Rob for yet another great review!

[aravindbabu]

You have done so much for this. Great effort

[minantraXOX]

ive had two, bought from the Nothing store in London, loved the look and the OS and its actually good quality BUT both returned as they constantly disconnected and would only reconnect once my phone was restarted! They acknowledged in the store that this is a known problem and said wait for CMF2 watch!!!!

[sephpatrick]

The CMF watch pro 2 just came out. I think you will be interested. 😊

[Smartphoenix]

😂Crap Watch. Thx for your Test ❤
Pls update your Test from The Pixel Watch 2 and Fitbit Charge 6. 🙏

[rakemgage]

you know i ended up buying this watch for the sake of having a new smart watch the is overall pretty good. Not perfect or even the best but good for the price with good materials and a amazing price if you just want a good looking smart watch for everyday use its perfect

[PollenJH]

Thank you for this video, was planning on buying a CMF Watch just because I have a Phone (2) (which is actually good unlike this watch). Decided on an Inspire 3 instead. Keep doing these, as it really helps out people in deciding what to buy! 👍

[mehboobb]

Looks very scientific and accurate analysis. Superb review. Love it.
