I tested an Amazfit product for the first time at the beginning of 2020, I had chosen the Amazfit GTS and was pleasantly surprised by the good price/performance relationship of the product.[b][b]At the same time Amazfit was launching a crowdfunding campaign on Indiegogo for the Amazfit X Curved, a new watch with a 92° curved screen and many features. I'm not what you call a fashion victim, for me a watch must above all be functional but I must admit that I was also seduced by its design.[b][b]The watch has a more premium positioning than the Amazfit GTS and outside of its screen, I don't directly see any features that would put the GTS back in a drawer. I will therefore try to determine whether the price difference of the Amazfit X Curved is justified.[b][b][b][b]linkManufacturer web site:https://en.amazfit.com/[b] How are my tests different from others on the web?
- I usually buy the devices with my own money, so price is just as important as you are! - I keep the devices for at least a few weeks (sometimes more) to see what they are worth in real conditions. - I answer (when possible) your questions to help you decide before you buy - no one pays me to do these reviews, so I'm completely neutral and independent... - My pages are not filled with ads

Waarom deze smartwatch?
I haven't tested many smartwatches so far, it's not my favourite topic, but I've come to appreciate this kind of product to the point where I no longer use my traditional watch.[b][b]I tested an Amazfit smartwatch for the first time in early 2020 and the release of this new model on Indiegogo was an opportunity to test a more premium model by paying more or less the same as an entry-level model. [b][b]The Amazfit X Curved comes with a 92° curved screen, which is an interesting innovation as I have always found that watches have poorly organised screens because of their shape. [b][b]In addition to the innovation around the screen, the Amazfit X Curved offers numerous sports features such as the Amazfit GTS with some new features such as the measurement of the oxygen level in the blood or a stress level measurement.[b][b][b]
Structure of my tests
I test products according to a pre-established structure (see below) to provide you with maximum information. Unfortunately, this takes a lot of time. Unlike some sites where products are tested on a single day, I use the products I test for a minimum of a few weeks and sometimes even a few months. If the test is not complete at the time of your visit, I invite you to come back later or ask your question in the comment section below.
[b][b]The Amazfit X Curved is delivered in a circular box marked with an X in the middle. The care taken with this type of packaging demonstrates the desire to position the Amazfit X Curved in a different segment from the other smartwatches I have tested so far.[b][b]The smartwatch is carefully wrapped around the X, the magnetic charger is integrated into this circular central island but you can easily detach it to use it outside its box.[b][b]The rest of the box contains a spare wristband and a small user manual.[b][b]The Amazfit X Curved left me with a positive feeling when I unpacked it, it is sober and elegant at the same time. [b][b]
The Amazfit X Curved was completely discharged when I received it, so I had to recharge it first before I could use it. After charging the battery, a QR code is displayed on the screen to start the configuration.[b][b]So I first scanned this QR code with my phone and ended up with an error message. I had exactly the same problem with the Amazfit GTS even though 6 months have passed since my last test. This is not exactly what I would call a good first experience. [b][b]What should I do? You need to download the Amazfit applicator which is no longer called Amazfit but Zepp. Fortunately, it is a free application. In the app you have to go to the settings to add a watch through a QR code. So I scanned the QR code and as with the Amazfit GTS it didn't work the first time. Once again it's a shame especially for a product that is positioned as a premium product. Finally, either, after two or three tries, the watch synchronizes with the phone and after a few minutes of updates, the watch is finally ready for use.[b][b]From the application it is possible to configure the watch such as choosing a new screen or activating services/notifications.[b][b]
[b][b]After setting up, the watch screen went off and no matter how much I waved my wrist or tapped the screen, the screen would not come back on. I thought this was a problem but in reality the screen came on when I pinched the watch. It's quite unusual, you have to see if it's a good choice in use.[b][b]
[b][b]As I wrote above, the Amazfit X Curved has a more premium positioning than the Amazfit GTS. However, it is made of plastic, probably to better fit the shape of the wrist. [b][b]Overall the level of finishing is good, the shape of the watch fits the wrist very well, the screen is very well integrated into the bracelet, there are no interruptions. [b][b]The strap is made of rubber, it's not exactly a premium choice either but I don't see how it could have been otherwise. The rubber allows for continuity between the screen and the bracelet, the whole thing is pretty good.[b][b][b]
The Amazfit X Curved can be controlled via Bluetooth by an Android smartphone or iOS using the Zepp application. The first pairing and configuration was no problem for me and I continue to receive notifications up to 5-7 metres away.[b][b]The Amazfit X Curved also has a GPS chip that makes it autonomous, so you can normally do outdoor sports without the help of a smartphone, the route will then be synchronised at the next connection with the smartphone. This should in principle be a strength, the problem is that the GPS simply doesn't work. I have done many tests outdoors and the GPS is looking for the signal without finding it.[b][b]Other buyers have confirmed to me that they have the same problem and I see complaints about the GPS in the comments of the crowdfunding campaign, so this is not an isolated case.[b][b]The fact that GPS doesn't work greatly reduces interest in this product. Amazfit responded to backers on Indiegogo saying that they were analysing the problem but quite frankly I don't think it's normal that such an important feature is not available.[b][b]
The battery is not the strong point of the Amazfit X Curved. Where an Amazfit GTS can last almost 2 weeks, the X Curved will last a few days at most. [b][b]For my first days of use I had set the screen brightness to maximum and activated the automatic switch-on of the screen with every wrist movement. In these conditions I obtained a little more than two days of autonomy with frequent use of the watch and about one hour of sport.[b][b]As I found this autonomy a little low, I activated the automatic brightness and reduced the display time of the screen. With these settings I obtain a 5 day autonomy with always one hour of sport.[b][b]So the Amazfit X Curved doesn't have an extraordinary battery life if I compare it to other models, but it won't let you go after 24 hours either. Charging time is about 2 hours, so you will have to organise yourself so that this charge does not have to be done in the middle of the day when you are likely to need your watch the most.[b][b]
The Amazfit's screen is quite unique in its shape. Most watches offer either circular or rectangular dials, but Amazfit has chosen a screen built in the form of an elongated rectangle to display a maximum of information without enlarging the watch. [b][b]This screen was one of the elements that motivated me to buy this watch and it did not disappoint me. The screen is of good quality, it is bright and the contrast is excellent. However, you have to get used to its shape and the movements that allow you to navigate through the interface. The watch is quite narrow, the left/right movements should be brief.[b][b]The screen can be turned on by the movement of the wrist, it lights up quickly but it will light up very often by a simple movement of the arm and this will have a negative impact on the battery life.[b][b]If you decide not to turn on the screen by movement , you must press the watch on its side. This gesture is totally counter-intuitive especially as the sensor is not easy to find as it does not offer much relief and is not placed in the middle of the side of the watch. I would have frankly preferred a button (even a small one) than this system with its almost unpredictable result.[b][b]
[b][b]The Amazfit X Curved is organised into 4 sections from the home screen.[b][b]Top screen:[b]This screen contains all kinds of shortcuts for configuring the watch, e.g. activating the power save mode, managing the brightness, switching to night mode.[b][b]Bottom screen:[b]This screen lists the notifications and messages you have received.[b][b]Screen on the left:[b]This screen is customizable and contains widgets such as the weather, your calendar or biometric data.[b][b]Right screen:[b]This screen allows you to access the phone's menu with all available features.[b][b]There is of course the sports section which contains a long list of sports recognised by the watch, there is a heartbeat measurement feature, a stress level measurement, a blood oxygen level measurement, an overview of goals, the weather and some other features that you can see on the video.[b][b]Although the watch measures your sleep, sleep measurements are not available on the watch. This is a very curious choice.[b][b][b]
Heart rate[b]I did several hours of sport with the Amazfit X Curved, each time using my Polar H10 belt in parallel. This combination allowed me to compare the two devices under exactly the same conditions.[b][b]The belt is in principle the most reliable product for measuring heartbeats.[b][b]I have listed below two elliptical bike sessions to compare the results of the two devices.[b][b]Session 1 - Polar H10[b]Average heart rate: 122[b]Maximum heart rate: 137[b][b]Session 1 - Amazfit X Curved[b]Average heart rate: 123[b]Maximum heart rate: 146[b][b]The average heart rate is almost identical but the maximum value differs. If I look at the graph in minutes per minute, the curves follow each other fairly well but the scale used by the Amazfit application gives the impression that the differences are greater when this is not the case. For this first session, the Amazfit measurement looks quite good with just a difference on the maximum value.[b][b]Session 2 - Polar H10[b]Average heart rate: 138[b]Maximum heart rate: 150[b][b]Session 2 - Amazfit X Curved[b]Average heart rate: 139[b]Maximum heart rate: 158[b][b]As in the first session, the average measured by the two devices is very similar, whereas the Amazfit measures a higher maximum value. The measurement was probably somewhat influenced by the poor position of the Amazfit at the start, but overall the curves are quite similar.[b][b]I tested another Amazfit a few months ago and had good results, this is also the case with the Amazfit X Curved but the maximum measurement seems more erratic or may be less reliable.[b][b]
[b][b]Sleep measurement[b]I have tested several watches that measure the quality of sleep and I have obtained quite different measurements each time. I don't have the possibility to compare these figures with a reference that would allow me to judge whether these measurements are correct. So I can only rely on my feelings.[b][b]The Amazfit X Curved categorises sleep according to several criteria, it measures the % deep sleep, % light sleep, periods of wakefulness, quality of breathing and heart rate. This gives a score based on these different indicators. I always get fairly low scores for deep sleep when I don't feel I slept badly. [b][b]The heart rate measurement undoubtedly influences the graph, I can see for example that my heart rate drops below 55 beats per minute, I had already observed the same kind of measurement on other watches.[b][b]All these measurements are interesting but as I don't know if they are reliable, I don't consider them a determining factor in buying the Amazfit X Curved.[b][b]
[b][b]Stress measurement[b]I have never attached much importance to stress measurement until now because I have always found these data to be fanciful. With the Amazfit X Curved I have changed my mind.[b][b]The stress level is measured automatically, but you can also provoke the measurement manually. This gives you an idea of how your stress level develops over a whole day. The stress level is low at night and fluctuates during the day. I was quite surprised by these measurements because they seem to be correct. I am measuring a significant difference between a working day and a rest day. I also see that the higher values correspond to times when the stress level was higher. If I have to get angry for one reason or another, I can clearly see the stress value skyrocketing.[b][b]However, I have noticed empty areas where I don't get any measurements, yet the watch was still on my wrist.[b][b]
[b][b]Oxygen in the blood[b]This is the second watch I have tested with this type of measurement and the results I obtained are the same as those I obtained with the Samsung Galaxy Watch 3. My oxygen level in the direction was always between 99 and 100. I obviously cannot compare with a medical device but the measurements match.[b][b]
Amazfit developed its own application to synchronise its products, this application was simply called Amazfit but was renamed Zepp. [b][b]The name change has not changed the way the application works, the content is exactly the same. The main screen gives an overview of the main indicators (sleep, heartbeat, number of steps, ...) but you can quickly access the other features of the application.[b][b]I find that this application is not well organised, I had already tested it with another Amazfit earlier this year and did not see any improvement. The application has been designed as a hub to aggregate data from many devices (e.g. a connected bathroom scale), the idea is interesting but even if you don't have other objects connected, these possibilities will still be displayed. [b][b]The access to historical data is not very easy either, sometimes you have to really search to find the information because the interface is not very intuitive. I think it's a pity because the interface of the watch is well designed and simple to use but the application is going in a totally different direction.[b][b]
The Amazfit X Curved is a watch that can be used without an application but if you want to access historical data you will have to use the application. The Zepp application is available on the Play Store and the App Store, so the watch can be used with a large number of phones.[b][b]However, I have not seen any other applications that work with the Amazfit X Curved where some other Amazfit models are available in Strava.[b][b]
The Amazfit X Curved runs on a proprietary operating system, which means that you will not be able to install any features other than those offered by Amazfit. This is not a big problem because the watch offers a fairly wide range of features anyway.[b][b]The operating system is very well designed, it is easy to use, responsive and offers a bit of customisation. If I had to find a negative point I would say that some texts are sometimes really small and despite the excellent contrast of the screen, I can't always read what is written on my screen. If you have good eyesight, that shouldn't be a problem, but if like me you are hypermetropic, that could also be a problem.[b][b][b]
The GPS does not work and sleep data is not visible on the watch.[b][b]
Compare Amazfit X Curved with the others
I assigned a score of 1 to 10 for each test that determines the strengths and weaknesses of a product. I am using 0 for criteria that have not (yet) been tested. A score of 1 to 3 indicates poor performance (and yes, it does), a score of 4 to 6 indicates average performance, a score of 7 to 8 indicates good performance, and a score of 9 and 10 indicates exceptional performance. . The score is calculated based on my measurements and when there are no measurements, it is a subjective opinion based on my experience.
The scores are not static, they change over time because the performance of new products changes and this must be taken into account.

Test / Review conclusion
When I test a watch, I wear it for at least a month every day. Among the watches I tested this year, the Amazfit X Curved is clearly my favourite but unfortunately this is a very subjective judgement as my objective score will not put it at the top of the ranking.[b][b]Why not? I like this watch for its size, it is very light, it is discreet, it is elegant. The screen is really beautiful and it offers a different experience. The operating system is simple and the Amazfit X Curved offers all the features you would expect from a product of this type. [b][b]Unfortunately the GPS does not work, the battery life is not extraordinary (although this is not a big problem), the pressure ignition system is not very efficient and the sleep data is not displayed.[b][b]In the long term I also wonder what will happen if the bracelet breaks as it is integrated into the watch. [b][b]I hope that Amazfit will correct the GPS problem and make some small changes to the operating system because if they do, this watch will appeal to a very wide audience.[b][b]Strengths[b]Screen (definition, colours, contrast, brightness)[b]Ergonomics[b]Wrist position[b]Finishing[b]Cardiac measurements[b][b][b]Weaknesses[b]GPS[b]No sleep data[b]Application not always very clear[b][b][b]
