Really can’t beat it for the price
Really like the dark and light green color. Battery life is amazing I typically charge it once a week with always on display on. Watch faces I wish there was more but let’s be honest a find a couple I like like radar sweep and chrono master and stick to them. Being able to read messeges without getting my phone out or seeing whos calling has improved my everyday life. App was really easy to set up and use. Wish there was a keyboard instead of just quick replys for texting. Overall I recommend to anyone wanting a simple watch that will track your steps good enough paired with your phone it’s fantastic. That wants something that looks nice and does the job with some personality and doesn’t want to change there watch everyday or two.

Fantastic for the price.
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.

Packed with Upgraded GPS L1 & L5 tracking & 4 Med Sensors
A lot of Good things to say about this Sport watch. I don’t know about reliability , but for accuracy, for med data like heart Beat, & Oxygen I measured those against my Oxi meter & Blood Pressure Kit and data was very accurate. The watch faces however, are not as Felxible/adjustable as others where some watches actually allows you to create them. This watch has a L1 & L5 GPS system which is highly reliable and unlike many other watches especially under $150 , will find a GPS signal within 3- 5 seconds per my test. It also has 4 sensors to give you more reliable health readings. It has as many, sleep mode that measures many factors. I had a $250 sport watch that did the same, (Recently died) and the results were within boundaries of the more expensive watch, but it did not track snoring . Battery life seems to be good though I only had this watch about 4 days , but I have been busy testing this one and another watch BVLRKSC . I tested distance accuracy with my Odo on my electric bike on both watches. The resutls were pretty good. You can spend a lot more $$ on other watches that have the same upgraded functions that the Pro 3 has, and not be any more accurate. Both watches are comfortable, though this watch tends to lean on less color, and less choices for dial display. I am leaning more on the other watch just for its Dial faces and easy choices , but its a tough decision because this one really packs a wallop for upgraded tech. The other watch you have to go into the App to sync up a GPS signal, that transfers to the watch (You don’t have to have the phone with you after that) in order to use GPS within seconds, otherwsie you wait 3 -5 minutes. This watch connections to GPS within 3-5 seconds thanks to the L1 & L5 GPS. One can hardly go wrong with these watches. The only thing that I have read on this watch was poor follow up with the manufacture if you experience problems etc. Hopefully that’s been addressed.

Practical but disappointing.
I wanna like the watch, but I immediately ran into a lot of limitations. First was the limit to only having 5 alarms at a time. I am diagnosed with severe ADHD, so I rely on alarms every day. Now they do have the reminder option, which I am using, but this leads to the other limitation. You can’t choose different notification sounds. Its not too bad, but I also have tinnitus from my time in the Marine Corps. A good piercing alarm sound is a need. The default one isn’t too bad, but it could be better. Also, the double tap for voice assistant, which is what I chose for the shortcut, doesn’t actually activate the voice assistant. It brings it on the screen, then it only works when you tap the screen. Just activate it on the double tap.My next complaint is the lousy customisation for watch faces. If you wanna use a customizable face, don’t expect to see any onscreen health, weather, calorie, or seconds display. You just choose a background, and it puts a generic time on the face. No extra features are visible. Lame. Let me add all the features to the custom watch faces, and it will raise the quality. This also brings up another limit. You can’t use any third-party watch faces. You can only use the watch faces that come with the Nothing app, which are all painfully generic and lacking creativity. And there’s a lot to choose from, which means they put all that time into like over 60 boring watch faces. When I choose a watch face, I need it to show the time, date, weather, seconds counting, BPM, battery life, and health monitor options.You know what else is super disappointing? You can’t send text messages. This watch came out in 2025, and you can’t send a text message… You can only send quick responses when someone calls you. It’s basically just a fancy beeper. They have a built-in calculator (which is nice), but you can’t send a text? Fire whoever thought it wasn’t a good idea to add text messaging. I was sending texts from a super outdated Samsung watch that came out in 2019, which let you use the old flip phone method of texting using the number pad. This was on a watch face much smaller than the CMF 3 Pro. There’s no good excuse why this watch can’t text.Just because you’re making a budget smart watch doesn’t mean you have to cut features that every single smart watch should have in 2026, whether they’re budget or luxury. Stop limiting your product for the sake of limitation.As for how well the health monitoring capabilities are, that remains to be seen. I do like the calculator, flashlight, voice memo, reminders, find my phone and the physical rotating crown on the side. Though, I worry itll be easy to break later down the road. The watch is at least practical, despite its limitations, but I can buy a practical watch anywhere for under $30. In this day and age, people expect more out of smart technology even if its technically a budget item. The world is running on smart technology. Yall need to catch up. If I can go out and buy a 4k TV for $200, yall can make a budget watch that sends texts and allows more customisation. I’m not over here asking for a James Bond level watch.

Better than Advertised
I have had this for kist over anmonth now, and I am very well impressed with it. I cant say really anything remotely critical of it, only praise.The battery is as advertised and lasts a week. It looks good, the strap is solid and comfortable. The health tracking features are very helpful to me. If you dont want a watch with 1000 exercise apps on it, this one is great and only has about 16.The cost seems right to me. It is a well thought out watch design ,and I hope to have it for years.

Great price, a base model watch that shouldn’t be called “pro”
The only thing I think they need to get rid of is the “pro” in their name. This is a good watch but many are going to compare it to its competitors.It’s a base model smart watch. It has basic fitness tracking, can read text messages, no voice commands, tells the time, etc. If you need more bells and whistles, this isn’t the watch for you.What I will say, what it does as a base model watch is excellent. I love the look, it’s durable, and the design stands out from other watches if you get the orange one. I work a blue collar job, so I’m carrying and moving things around a lot. This watch can take a beating, and it still runs fine. I don’t need it to talk to me, I don’t need it to text for me, I just like the notifications, time, fitness, etc I can glance at when I need to.If you want a general, standard issue smart watch. This is it. The price is perfect. If you want a lot more, consider the apple or android alternatives. This is good for those looking for a good priced, nothing fancy smart watch.Nothing, if you’re reading this consider for the next one, the Watch 4, dropping the pro name. I think the name will make better sense for the watch you’re getting.

Love(d) the watch/features, not a fan of their Customer Support
I had this watch around two weeks before I had to send it back. Do not get me wrong, I loved the watch fully, but a fatal flaw in the charging cord absolutely ruined everything.I have been watching Nothing for several years now, and I have wanted to get into their universe of electronics for a while. So when a great sale came up for the CMF Watch 3 Pro and I had the money, I bought it. Shipping was quick. The box is a bit simple and straightforward.Set up was quick and straight forward after downloading the app and signing in. If you are not already signed up on the Nothing.tech site, you will need to make an account. I put the band on the watch, toggled on and off some of the notifications, set a watch face, and I went about my day. The functions seem to be pretty good and straight forward.I wanted this watch for many of it’s core features; sleep tracking, step counter, BPM, stress levels, etc. I wasn’t really concerned about calling out or answering calls on this watch, so I can’t comment to that. I could read notifications from apps I allowed it to pair with. It does have some quick responses, but I did not see an option to talk-to-text like some watches have. I would clear out my messages every so often, because it does seem to have a little bit of a limit with how many it stores/receives.I don’t have a way to confirm the BPM, or the accuracy of the other main features, but I did notice something with the sleep tracker feature. I have a habit of “laying awake for a while”, and I would notice that it would count some of that as sleeping/napping. Yes, it has the ability to track naps, as well, which was really cool! Everything was easy to access within the app, and I could check my stats as often or as little as I would like. It was able to help pause, forward or reverse my songs on Spotify without issues. The screen was beautiful, simple, and easy to read even out in daylight. The response was sometimes perfection, and other times there would be just a bit of a hesitation between touch/gesture. But it wasn’t enough to be upset with it, you know?The battery was phenomenal!! I could have easily gotten over a week out of it, if I wanted. I charged it when it would get down to around 40% or 20%, and it did not take long to charge the first time.My problem comes from this; The second time I went to charge it, I noticed it was taking a bit longer than the first time. If you aren’t aware. The charger cable is one of those magnetic pogo pin cables where you have to line it up just right on the back of the watch. If you so much as blink while setting it down carefully, you risk the cable popping off. Or at least with mine, it seemed to be this way. So, the second charge took a bit longer. I put the cable away safely without really looking at the cable. I ordered a second watch as a gift, and I was setting up that watch and figured I would just pull out my cable and charge it up. That is when I noticed it wasn’t charging at all now. To my discovery, one of the pogo pins was stuck down.I figured I could reach out to Nothing’s Customer Support and see if I could get a replacement cable, because some of the reviews I had seen about third party cables were not super good. (See; cable melting, pogo pin area melting, melting the watch, etc.) So I emailed the Customer Support in hopes that they could help me with this issue. I was asked to take pictures. I take the pictures, and they respond back with, “We have determined to be man-made damage, we will void this product. You will have to pay for a replacement cable.” If you research/Google these types of cables, read reviews even on their own Nothing Customer Support over the years, etc., you will absolutely find reports of pogo pin spring failures, pins getting stuck, susceptible to corrosion, dirt, etc. I responded that I was confused by their ability to just determine that it was “man-made damage” when this happened with no part on my doing. I take really great care of my electronics and their assigned charging cables. The cable was always stored in a safe spot. When I received the cable, I noticed that one of the pins was a little lower. I have no clue if I was sent a used watch or it was caused by potential temperature shifts/humidity between where it was stored, shipped, to my house? Either way, Customer Support sent me in circles, offering to “send me a link to a new cable”, and when I would explain that I was weary of third party cables, and I was unable to find legit cords, they assured me they would send me to “verified cords”.Spoiler Alert; They would Not in fact send me “verified cord links” to purchase. Instead they asked for me to send Proof of Purchase of the watch. After I did so, they wiped their hands of me and told me to go through Amazon for a replacement, because I was still within my 30 days return window ((thankfully!!!)). When I initiated the replacement, I was only able to do the “Return” for some reason?? Amazon has changed some of their features, because I was hoping to get a replacement.Honestly, I would have loved to have just kept the watch and get a verified legit Nothing charge cord sent, because this is a known issue with those types of cables. I really hope that going forward, Nothing CMF will find a way to use the wireless coin chargers and get away from the pogo pin type chargers. I know they are on the “cheaper side” for smart tech, but it would honestly elevate the quality, because again… I really loved the watch!!

100% honest review
So honest review here, I got this Saturday the 10th of October. It’s currently October 21 I charged it up fully and have not charged it since and I still have 18% battery left. So off the bat I’m sold with just that. Being able to have a few different options for my watch faces and not having to charge nightly compared to my Apple Watch was a huge plus when I was looking online for alternative watch options. The calling function (which I rarely use but wanted to try) was super loud and the other end could hear me clearly. Now I did not have advanced sleep tracking or the 24hr heart rate going. Just barebones notifications. Now the downside I have is that it doesn’t hold connection with an Apple Watch very well but hoping that will be improved in the future, but it’s not that hard to open the app once or twice a day and hit connect again. I would love to see more watch bands come out for this product and maybe a more advanced water proofing in the future if they release another version. But all in all definately worth the money, functions as a watch first with added extras vs an Apple Watch being more of a tiny phone on your wrist.

Good for the price, but might not buy again until V5 or V6
I like it, its my first smartwatch and it has just what it needs to have. I don’t really care for more fancy stuff on it as I just wanted something to count my steps and maybe give me some health metrics.I like the simple design and enjoy using it.Now the bad, maybe this deserves 3 stars and not 4…The design even if it looks good, the edge is constantly being hit by everything. I guess the design is supposed to protect the screen but I have a protective glass and now the edge is getting dents here and there, its too soft to handle any accidental drop or bumps against a wall.The strap is uncomfortable for me, its missing a hole in between as its either too loose or too tight and the lower part where the sensors are located is uncomfortable compared to a normal watch.Overall I would still buy this as a first time smartwatch owner, but most likely won’t buy CMF again until maybe version 5 or 6 when they make it more ergonomic and durable, watches shouldn’t be uncomfortable and so brittle.
