Kospet Rock review / test

Category: Smartwatch

Kospet is a Chinese brand founded in 2018 which mainly sells smartwatches. I hadn't yet had the opportunity to test a connected watch from this brand, but Kospet has already launched many models and the brand is beginning to make a name for itself in Europe.[b][b]For this first test, I will try the Kospet Rock, this smartwatch is of a different type from what I usually test. It bears its name well because it is a smartwatch that is designed to resist shocks with its waterproof armour and its resistance to pressure.[b][b][b][b]linkManufacturer web site: https://www.kospet.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

22/01/2021 Reception of the Kospet Rock, start of the test[b][b]

Waarom deze smartwatch?

As I wrote in the introduction to this article, the Kospet brand has already been around for a few years and I had not yet tested any of its models. So I had to get started.[b][b]Kospet smartwatches generally offer a great deal of functionality for an attractive price. This is often the case for Chinese manufacturers, but sometimes this is at the expense of quality and/or reliability. I will therefore test this new Kospet Rock with the same criteria as the other smartwatches and see if it can stand comparison with other Chinese brands such as Xiaomi or Amazfit.[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 Kospet Rock is delivered in a compact box containing the bare minimum (smartwatch, charging cable and manual). Due to the positioning of the watch, I expected something a bit rougher but the watch is nicely packed in its display as if it were on a shop display.[b][b][b][b]

First configuration

The Kospet Rock can be used without an application, this is obviously not very interesting but I appreciated the fact that I could make a first overview of the watch without having to synchronise it with an application. [b][b]The Kospet Rock uses the Da Fit application to synchronise its data, I will come back to the application a little later in this test. If there are two things that bother me with the connected watches it is on the one hand the total lack of standardisation for the recharging cables and on the other hand the need to download a different application for each brand. [b][b]With the Kospet Rock I had to download yet another application, my phones are now polluted by all sorts of applications for each watch I tested. Luckily the application for the Kospet Rock is really well designed and the configuration was one of the simplest and most intuitive I've been able to test so far. The watch is recognised immediately, no QR code is needed, a simple Bluetooth connection is all that is needed and in less than a minute the watch is fully operational.[b][b][b][b]


[b][b]The Kospet Rock was not designed to win a beauty contest, nor is it the kind of watch to be used to show off in society...yet I find the finish of this watch to be quite successful, the Kospet Rock has the merit of being different. It has a rougher look than most models on the market but it offers a large screen, buttons that do not engage when you bend your wrist and yet it is not too heavy.[b][b]I have tested many watches in 2020 and my friends and family don't even notice the changes in the watch anymore except for this Kospet Rock where my 8 year old son noticed the difference immediately, he even thought this watch was more beautiful than the others. The opinion of an 8 year old child is obviously not representative of the population to which the watch is addressed but I wanted to show by this example that the Kospet was different.[b][b]The Kospet Rock is easy to use, it has two large buttons which can both be used to turn the watch on or off, the bottom one can also be used to go back in the menus.[b][b]The 1.69" screen is also one of the good surprises, as reinforced products like this Kospet often sacrifice screen size for screen protection. This is clearly not the case here.[b][b][b][b]


The Kospet Rock uses Bluetooth 5.0 to connect to your phone, however it does not have its own GPS sensor, which means you will always have to use it in combination with a smartphone to get your position.[b][b]

Battery range

The Kospet Rock's battery is probably one of the best I've had the opportunity to test. When I received the Kospet the battery was at 75% and two weeks later it was still at 40%. I use the automatic switch on the screen when my wrist moves and I set the brightness to minimum as it was sufficient. I do between 1 and 2 hours of sport a week.[b][b]

Screen quality

[b][b]As I wrote above, the Kospet has a 1.69 inch screen and is probably one of the largest screens of any watch I have tested. A screen of this size allows more space for the information to be displayed on the watch and I find this a real advantage. On some watches I find that the legibility of the information is not always very good to the point that some texts are no longer readable if you don't have an excellent view. I didn't have this problem with the Kospet, even the configuration menus are perfectly readable.[b][b]The Kospet uses a rather bright LCD screen, the blacks are not black like for an amoled screen but at this price you can't find a watch with an amoled screen. The pixels are visible if you pay attention to them but for this price level, I think the screen is really good.[b][b]


[b][b]In the same price range as the Kospet Rock, there are more and more [b]over-equipped watches offering functionalities that go far beyond the usual sports modes. The Kospet also goes in this direction by offering the following features:[b][b]- Heart rate measurement[b]- Sleep measurement[b]- Measurement of the oxygen level in the blood[b]- Blood pressure measurement[b]- Weather Summary[b]- Shutter release for taking pictures (only works when using the Da Fit application)[b]- Control of the music player (I tested it with Deezer and it works flawlessly)[b]- notification (sms, whatsapp,...): the notifications work really well on the Kospet and unlike many other watches I have not encountered any bugs. The notifications are listed one after the other and Kospet receives both sms and whatsapp notifications instantly. Emojis or other non-text content are not displayed, only the text is visible.[b]- stopwatch / timer[b]- 20 sport modes[b][b]It should also be added that the watch can withstand pressure up to 3 atmospheres (30m depth under water).[b][b]


To test the reliability of the heartbeat measurements I compared the Kospet Rock to my Polar H10 belt. I used the belt at the same time as the Kospet Rock and here are some examples.[b][b]Session 1 - Kospet Rock[b]Average heart rate: 117[b]Maximum heart rate: 140[b][b]Session 1 - Polar H10[b]Average heart rate: 137[b]Maximum heart rate: 161[b][b]Session 2 - Kospet Rock[b]Average heart rate: 96[b]Maximum heart rate: 110[b][b]Session 2 - Polar H10[b]Average heart rate: 136[b]Maximum heart rate: 154[b][b]The measurements are therefore unreliable and the discrepancy is sometimes very large. For session 2, I even tried to change the positioning of the watch to see if the measurement was better but it didn't change anything. This is unfortunately often the case with watches in this price range.[b][b][b][b]Measurements of blood pressure and oxygen in the blood are also unreliable, but so far no manufacturer has been able to produce reliable measurements.[b][b][b]


With every watch I test, I have to install another application almost every time. Some brands do not develop their own applications and are therefore forced to use third-party applications that do not always work properly. If I look at what I have on my phone, I now have a long list of applications that are no longer of any use to me when I switch to another application.[b][b]So I wasn't very enthusiastic about downloading yet another new application for Kospet Rock and yet I had a nice surprise. Kospet Rock works with the Da Fit application, I had never used this application before. The application is very simple, you don't have to search to find the information, the data of the watch is consolidated intuitively on the home screen. If when opening an application I have to start thinking about where information is located, it's a bad sign, I didn't have this problem with Da Fit. [b][b][b][b]


The Kospet Rock is compatible with all smartphones compatible with the DaFit application. So just download this application to see if you will be able to use the Kospet with your phone.[b][b]

Operating system

Kospet Rock uses a proprietary operating system, so it is not an open system where you can install applications. In this price range, I haven't yet seen a watch running a WearOS-like operating system.[b][b]The Kospet Rock is really easy to use, the features are where you expect them to be. The top screen is reserved for shortcuts as it is the case for many watches, the bottom screen is reserved for notifications. The screens on the right are widgets giving access to the main features of the watch and the screen on the left gives access to a kind of icon cloud giving access to the applications. [b][b]The interface is simple and clear but I also liked the consistency between the different screens. On some watches I sometimes have the impression that several people designed the menus without talking to each other, this is not the case with the Kospet. All the screens (including the configuration) are perfectly readable and follow the same graphic charter.[b][b][b][b]

Encoutered bugs

The "Do not disturb" mode does not seem to work because the watch still lights up at night.[b][b]

Compare Kospet Rock 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

The Kospet Rock is a watch with a rather special style, it is designed to withstand shocks. This makes it look a bit more brutal than the other watches I've tested but I think the design is pretty good. Due to its shape, the Kospet has a large screen that offers good readability without causing discomfort on the wrist.[b][b]The Kospet Rock is easy to use, the menus and features are where you would expect them to be. The interface is also well designed, I didn't find any inconsistencies in the design.[b][b]The battery life is probably one of the greatest strengths because in normal use it can last more than two weeks. [b][b]Of course, not everything is perfect and in this price range, the most common problem is the reliability of the measurements. Cardiac measurements are not reliable. If you are a sportsman and you want to measure your performance, you may be disappointed.
