Kospet is a very active brand and reminds me a little of Xiaomi which launches dozens of new products every year. I tested the Kospet Rock, The Kospet Magic 3, the Kospet Prime S and it is now the turn of the Kospet Optimus 2. [b][b] The Kospet Optimus 2 is a stand-alone watch that can be used without a smartphone like the Lemfo LEM15 or the Kospet Prime S which I have also tested. The Kospet Optimus 2 can make and receive calls (ditto for messages), it runs on Android with access to the Play Store which greatly broadens the functional horizon of this type of product. Running apps or phones with a watch is no longer science fiction. [b][b] The Kospet Optimus 2 is a complete watch that differs from other watches of this type (and in particular the previous model Kospet Optimus) on several elements such as a more powerful processor, a version of Android more recent, a better battery and especially a Sony camera from the world of smartphones. This camera is also adjustable, this avoids having to graft two cameras on the same watch. [b][b] Worldwide release scheduled for July 28, 2021. The watch is available on Kospet official website, there will be stock in Europe which will save you from having to pay taxes. Introductory price: 176.99 $ (+/- 150 €) with the promo code 333OPTIMUS2
- 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
07/20/2021: start of the test before launch [b] 07/28/2021: official launch of the watch on the Kospet.com website[b]
Waarom deze smartwatch?
I test watches because I like this type of product quite well and it is a product that I use on a daily basis, so I don't have to find free time to test this kind of product. However, I only have two arms and since it takes me 2 to 3 weeks to test a watch properly, I have to be selective. [b][b] I tested a first Android watch with the Kospet Prime S, I was positively surprised by the ability of this watch to run Android in such a natural way but the autonomy of battery was too low. Kospet is now launching another Android watch that offers bigger battery capacity, better camera, better processor and more sports modes. As this is the third Android watch I have tested, I am starting to have enough hindsight to compare the different models tested. [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.
The packaging of the Kospet Optimus 2 strongly resembles other watches of this type, the box contains the following elements: - the watch [b] - the flexible silicone strap [b] - a charging station [b] - a magnetic cable [b] - a manual [b]
The Kospet Optimus 2 is a standalone watch so it doesn't need an app and I even have to say that is not a bad thing because the app offered by Kospet to sync the watch is really not a good application. You almost have to consider this watch as a smartphone running Android because after startup, you must enter your PIN code and for the first configuration you will have to configure wifi (or 4G) to be able to connect. The first configuration is no problem, you just have to get used to the size of the screen because even if the functionalities are similar to that of a telephone, the screen is significantly smaller. [b][b] You can associate your watch with the Gaofit application which allows you to consult the data collected by the watch, but this application is not complete enough. There are a lot of translation issues but I can cope with that. On the other hand, the data collected by the watch are too brief, it is for example not possible to recover an outdoor sports course. [b][b] The watch allows unrestricted use of the Google Play Store. When I logged in for the first time, I received an alert on my Google account indicating that a new device had logged into my account ... so far this is normal but the watch has presented itself as a Redmi 8 from the Play Store, so I guess all visible apps are compatible with the Redmi 8. [b][b] So you can install just about any app, that's a feat technological but we must not forget that it is a watch. Beyond the possibility of downloading an application for a watch, this application must still be able to function correctly on a watch. The applications are designed for smartphones with large rectangular screens, the watch has a small circular screen. So it's not always very convenient and sometimes it just won't work because the app will appeal to features that are present in the phone but are not present on the watch. [b][b][b]
The Kospet Optimus 2 has a good level of finish although overall it is made of plastic. The choice of the type of plastic, the differences in texture and the metallic effect dial give a more polished appearance than that of watches entirely constructed in a homogeneous plastic. [b][b] The 1.6 inch screen is very large and offers a very good experience, I will come back to this later in this article. The blue button is used to turn the watch off / on, the bottom button allows you to go back a notch. The watch is also equipped with a speaker and a built-in microphone that will allow you to listen to music or make calls. The sound quality is not extraordinary but the volume is good enough to be audible in most conditions. [b][b] The flexible silicone strap adapts quite well to the wrist but the movable part which avoids keeping the protrusion of the strap close to the wrist is quite difficult to move. If it slips close to the closure it will require an effort to detach the watch, something that can quickly get annoying if you have to quickly detach your watch. [b][b] The watch is not designed for use in water, the mobile camera is probably the cause.
The Kospet Optimus 2 offers full connectivity, it can connect to wifi or 4G to surf the internet or use applications. It has its own GPS sensor and it synchronizes with your phone via Bluetooth. The wifi and 4G work quite well where I had obtained a rather mediocre speed on the Kospet Prime S. The GPS on the other hand works correctly with Google Maps but when it is necessary to use it for sport, the detection time signal is sometimes longer and sometimes the signal cannot even be found. I had done a 10 km bike ride without the watch picking up the signal.[b]
The battery is clearly the weak point of Android watches, but the Kospet Optimus 2 offers better autonomy than the other watches I have tested. It has a 1260mAh battery where most watches are below 1000mAh. I think the Optimus 2 manages the consumption of applications better, it allows you to see the evolution of consumption and has an "energy saving" mode. In the end, I get an autonomy of about 3 days where I did not manage to exceed 2 days with the other watches of this type that I have tested.[b]
The screen of this watch is of very good quality even though it is not an amoled screen. The resolution of 400x400 on a 1.6-inch screen offers a very crisp and very precise rendering that allows you to read small characters. The contrast is less good than an amoled screen but the screen is perfectly readable. You have to push the brightness to the maximum to be able to read the screen when the sun is shining and it will probably be necessary to change the orientation of the screen because the lighting of the watch screens is not as powerful as that of the phones, l The mirror effect also plays a role. The screen is readable outdoors, but direct sunlight will decrease readability.
The Kospet Optimus 2 is a feature rich watch and there is more to this than just sports features. This watch runs on Android 10.7, so it can download applications from the Play Store, it has a browser for surfing the internet and natively integrates Google Search with voice control. Google Maps is also directly integrated into the map, the application uses the GPS signal from the watch. This watch is managed like a smartphone but you have to be able to get rid of the keyboard as much as possible, which is too small to write long texts. Writing an SMS or entering the address of a website is quite possible but it is very laborious. [b][b] I made a video to explain the different features in detail (only in French). [b][b] In summary: [b] Telephony [b] The watch reacts quickly when 'we receive an incoming call, the other watches I tested did not respond right away. Writing text messages is as laborious as ever and there is no voice command to dictate them, you just have to make do with the pre-recorded messages. The call volume is higher than on other watches, which should allow the use of the watch in almost all conditions [b][b] Parameters [b] The parameters are the same as on other Android watches but this watch also has a battery manager which not only allows you to monitor the battery consumption but also to activate the "economy mode" of energy ". [b] Sports modes The watch allows you to use around thirty sports modes where other watches were more limited but unfortunately the Gaofit application does not use the data from the watch. [b][b] Applications / Play Store The Play Store is perfectly functional, the watch looks like a Redmi 8 in the store, so it potentially has access to a very large number of applications. Unfortunately, these applications were not designed to be used on a watch, so in addition to the ergonomic issues related to the size and shape of the screen, there are compatibility issues. The apps are designed for phones and make use of features only available to those here. Advisory-type apps should work fine, but more sophisticated apps like the one that use the camera or gps may not work properly. [b][b] Camera The Kospet Optimus 2 is equipped with a Sony IMX 244 13 million pixel camera where most watches use unknown sensors from maximum 5 million pixels. The quality of the photos / videos cannot yet compete with the photos / videos produced on smartphone but it is better than what I got on other watches.[b]
Not yet available / tested[b][b]
The Kospet Optimus 2 can be combined with the Gaofit application but unfortunately this application is far from being complete and as complete as applications like Zepp, Mi Fit or DaFit. The app does not fully utilize the functionality of the watch, it is too basic, and there are a lot of translation issues as well. I will not go into the details of the application because I have already done it several times on other watches, I regret that Kospet did not choose DaFit because this application works with other watches of the same brand .[b]
The Kospet Optimus 2 does not need an app to be used to its full potential, so there are no compatibility issues.[b]
I added a video introducing the operating system a little earlier in this article. The Kospet Optimus 2 uses Android 10.7, I didn't notice a lot of differences with the Lemfo LEM15 or the Kospet Prime S. The battery management is more efficient, some images are different, the customizable dials are different but the system works broadly the same on other watches.[b][b]

Compare Kospet Optimus 2 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
Ten years ago, we marveled at seeing phones capable of surfing the web and taking pictures. Nobody is amazed by that today because this type of use has become so common in all layers of the population. We now see more and more watches capable of doing the same thing and from a technological point of view it is very interesting but unfortunately the contents (websites, applications, ...) are not suitable for consumption on a watch. So I cannot blame watches for the lack of adaptive content, but this type of watch is becoming more widespread, we must expect that the content will also evolve to offer a truly more successful experience. [b][b] If we disregard this lack of suitable content, I can only applaud the success of Kospet with this Kospet Optimus 2. This watch is at the time of writing this article the best Android watch that I was able to test. The autonomy is still not extraordinary but it is 3x better than the competitor watch from Lemfo. The telephony also works very well, the 4G signal level is good and the watch reacts quickly when it receives a call. [b][b] Watches are not intended to replace our smartphones for taking photos and videos, but this Kospet takes a step in the right direction by offering a single camera for two types of use (selfie and normal photo). Kospet chose to use a Sony IMX 244 producing photos in 13 million pixels, it is a feat for a watch. The quality is not yet at the level of a smartphone but the progress compared to other watches I have tested is visible. [b][b] The Kospet Optimus 2 is easy to use, it performs very well overall but it is clearly not a mainstream watch. It is aimed more at an audience of geeks looking for new things and who are also ready to accept some concessions. The watch is technically capable of replacing a smartphone but this is not always of interest because the lack of suitable content reduces the interest in certain functions a little. While waiting for the applications to be adapted you will always be able to shine in society by showing what your watch is capable of, it is the kind of gadget that always amazes ... Take advantage because the day when all watches run on Android, you will have to find another type of gadgets to assume your geek status.[b]Strengths[b]- performance [b] - battery life (compared to the competition) [b] - screen readability [b] - ease of use despite the number of features [b] - sufficient speaker volume [b] - photo / video quality superior to the competition [b][b][b]Weaknesses[b]- autonomy still quite limited [b] - Gaofit application not sufficiently successful [b] - wristband attachment not practical [b] - variable heartbeat reliability (depending on the intensity [b][b][b]
