Like a barometer, an altimeter measures atmospheric pressure by translating it into altitude, aiding in faster GPS location detection for navigation applications, as well as tracking how many floors we have climbed for health applications.
Gyroscope
A sensor that helps the device know its position in space. For example, it allows the device to understand when we turn our wrist to look at the screen.
Heart Rate

Embedded heart rate monitor.

Oximeter

Measure the amount of oxygen in the blood.

Sleep Monitoring

Recording of heart rate and breathing during sleep and diagnosis of problems according to the product. (e.g. restless sleep, lack of deep sleep, etc.)

Compass
Updates our device with its orientation, assisting in the use of navigation applications such as Google Maps.
Protection
Splash Resistant, Dust Resistant, Scratch Resistant
ATM Rating
5 ATM

ATM Rating

The ATM rating on smartwatches indicates their level of water resistance, which tells how well the watch can withstand exposure to water and various pressure levels.

3 ATM (30 meters): Suitable for everyday splashes, rain, and hand washing.

5 ATM (50 meters): Light swimming, showering.

10 ATM (100 meters): Swimming, snorkeling, water sports.

15 ATM (150 meters): Advanced swimming, water sports.

Battery

Battery Capacity
500 mAh

Battery Capacity

Most smartwatches have a battery capacity of around 200mAh. 2. The size of the battery is not always indicative of the autonomy, as this largely depends on the features of the smartwatch and the functions we have active. 3. For example, a smartwatch with a large color touch screen and 24-hour heart rate monitoring will often require charging even if it has a larger battery than a simpler smartwatch.
Battery Life
16 days

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.

    Overall, I was pleasantly surprised.... because I have other Kospet watches, I knew their quality... but now the new T4 and T4C have stepped up a level...
    The app is very good and has quite a few watchfaces.... The measurements are excellent... compared to the Huawei Watch 4 Pro Space Edition...
    As soon as I saw it on Skroutz at a price cheaper than the China price... I couldn't resist....
