  • Battery Life

    Battery life shows how many days the smartwatch can operate without charging.


    It depends on the battery capacity, but also on how much you use it (e.g. active display, GPS, notifications, etc.).


    For example, a smartwatch with 2-3 days of battery life is ideal for daily use with all features enabled.


    Models with 5–10 days or more are suitable for those who do not want to charge often or use it more "lightly".


    The value is especially meaningful when comparing products from the same manufacturer.

  • Display Type

    AMOLED

    Advanced OLED screen type with better visual experience, almost perfect black performance, thin and light but with higher energy consumption than Super AMOLED.

  • Waterproof

    Hand Washing

    You don't need to remove your watch every time you wash your hands. The smartwatch is water-resistant, fully covering frequent washing, making it practical for every moment of the day.

    I have had it since the summer of 2022 and so far, except for a glitch it had (the screen froze) and after I plugged it into the socket it returned, it is an excellent choice for its price (I bought it for 35 euros from Skroutz).
    The amoled screen is amazing, comparable to the Apple Watch 5. Additionally, it has been exposed to a lot of water during handwashing and showers (I haven't tested it in the sea, but in general, it's a good idea not to put such products in salty seawater), without any problem.
    As for its functions, it has heart rate monitoring and an oximeter, which, according to parallel measurements I made with a medical sphygmomanometer and oximeter, are accurate.
    There is no need for any other health function, as all the others are useless and count in the clown's wedding, even in smartwatches that cost 500 euros.
    It is not a coincidence that Apple does not incorporate more functions, as they know that currently, there is no suitable technology to operate satisfactorily in smartwatches.
    The application is its weak point, so if you buy it for this reason, you may be disappointed. It's not that it doesn't work, it just has its issues.
    Overall, a very honest purchase, which remains to be tested over time.
