Description

The Stratos 4 is a "beast" with an AMOLED display and Dual-Band GPS, designed for those who want a complete overview of their training and health without compromising on build quality. It is the ideal choice for those who want to start their adventures with a "reliable" tool that looks and works like an expensive one.

Why does it "rock" in its category?

  • Dual-Band GPS with 6 Satellite Systems: At this price, it’s almost unbelievable. It uses two frequencies (L1 and L5) to “lock” your position with accuracy, even if you’re running in the forest or between apartment buildings.
  • Impressive 1.43" AMOLED Display: With brightness reaching 1,000 nits, the Stratos 4’s screen offers vibrant colors and excellent clarity, making data reading a breeze.
  • Sturdy Construction: It features a zinc alloy bezel and stainless steel buttons, giving it a robust feel that has nothing in common with a “cheap” watch.

Battery life that won't let you down

Stratos 4 is built to last:

  • Typical use: Up to 30 days.
  • Heavy use: Up to 18 days.
  • With active GPS: Up to 45 hours (enough to record even an entire Ultra race).

Health & Fitness

  • Advanced Biometrics: Monitors heart rate, blood oxygen (SpO2), and stress levels 24/7.
  • 170+ Sport Modes: From running and cycling to more specialized sports, the Stratos 4 tracks everything with precision.
  • Bluetooth Calling: You can answer calls directly from the watch, which is rare for such "outdoor"-oriented watches.

Swimming

The Zeblaze Stratos 4 is a GPS smartwatch for swimming, designed to monitor heart rate and record distance, pace, stroke count, SWOLF, and other metrics, both in the pool and open water. 

Tools for the Outdoors

  • Built-in Barometer & Compass: Essential for every hiker who wants to know their altitude and direction.
  • Weather Forecast: Live weather updates so no rain on the mountain will catch you by surprise.

Fantastic watch for its price
Very honest and does everything, without lagging

The battery just doesn't run out...

As for waterproofing, I just get it wet, I don't need to submerge it completely, so I don't have a full opinion

The watch is very good value for its money. I have paired it with iOS using the Gloryfitpro app. I have also connected this app with Strava so I can view activities like running, etc., with maps. Its battery lasts quite a while. Its design is beautiful. Quite satisfied and I am waiting for the summer to try it out in the sea and also to see its durability over time.

update 8-6-2026. I was very satisfied with the watch until I swam in the sea and the next day I noticed that the watch discharged immediately within about 3 hours.

    This review is about the colour: Black

    It stops recording activity whenever it wants.
    One of the buttons, after 3–4 months of use, has to be pressed harder to activate.
    The compass goes out of alignment very often and needs to be recalibrated.
    The app logs out on its own quite often.
    Many times, even when my heart rate was elevated, the watch showed my resting heart rate—that is, while running, 55 beats per minute.
    If you just want to count steps, it’s OK.
    It’s not worth it, not even from an overseas website where it’s half the price. Better to get a well-known brand.

    This review is about the colour: Black

    It is admittedly a watch with limited capabilities. It can do very specific things, but at this price of 50-70 euros, I don't know if there is really anything better. It is not for swimming in the sea; it is for walking, running, and generally activities on land, and of course connection to a mobile phone for calls, messages, etc. Since what matters to me is battery life, I did a test: operating it almost exclusively as a fitness tracker (step and running tracking) and a recorder of vital signs (heart rate, blood oxygen, stress, sedentary reminder), its battery lasted exactly one month (and 10% was left). I count that as a positive. The fairest thing for this particular watch would be if I could give it 4.5 stars.

    Generally, it is quite good for its money, but it has a very serious issue with its battery life. With almost minimal use and power-consuming settings turned off, it barely lasts 4 days. I would not recommend it to a user who wants it for all-day use in a similar way to a phone. If you use it like a phone, it may even need charging every day.

    I’ve had it for 12 days and it gave up the ghost! While I had been satisfied with its measurements and battery life, one morning the buttons suddenly stopped working and it kept restarting continuously! Too good to be true! If you don’t spend over 300 on a truly waterproof watch for swimming, not diving, and with good measurements, there isn’t one!

    This review is about the colour: Black

    It is a typical Chinese smartwatch, one of those you find for 50 euros.
    In reality it is a clone of the DM58 OEM model, sold under various Chinese brands.
    For the money, it is good.
    Its negative point, classically, like all cheap Chinese watches, is the non-existent vibration. You miss notifications because your wrist does not feel the vibration.

    I regretted buying it.

    As for water resistance, only for showering. Do not swim with the watch.

    This review is about the colour: Black

    UPDATE 05/07/2026: Unfortunately, we drop to 1 star since after just 3 months of use and 4 swims in the sea the watch gave up.
    Coming from other smartwatches, I will say that I was disappointed by this one and had higher expectations.
    The UI freezes quite a bit, making the use of the built-in apps annoying.
    The notifications that come from Messenger, for example, you can rarely read the message since it gives priority to the sender's full name, etc., with the result that you have to manually tap the notification to read it, so the whole point is lost for me personally.
    Positive and nice lens, but in my opinion in the wrong place.
    Respectable battery life with everything on and quite a few notifications, it lasts more than 7 days without a problem.
    Personally, I would recommend going for something else

    Bought almost a month ago, battery lasts 8 days with everything turned off, otherwise sturdy construction, beautiful and good for its price. If it hadn't caused eczema on my hand, probably due to an allergy, I would have kept it, but Huawei is the only option.

    Good but I think there are still some things missing for it to get all 5 stars.
    On the downside, it (probably) doesn't have automatic brightness, you can't connect, for example, all your phone's apps but only some that the app specifies.

    For its price, as a beautiful Smartwatch, it is very good. It has quite a few functions. I have no opinion about the accuracy of its measurements. Honestly, it looks a lot like Garmin and the flashlight it has, which cannot be compared in intensity to the €1200 watch, but at night it will help you! The battery definitely lasts 12 days, maybe more with simple use. The speaker is very good. The call quality is very good. For the 80-something euros, I think it's fair. You can also add whatever watch face you want through the app! I think it's a fair purchase!

    Excellent watch, easy to operate from the very first moment. The LED flashlight is very useful. The battery lasts 10 - 12 days with normal use. So far its measurements seem accurate. It is very lightweight and comfortable on the wrist. It is definitely value for money. The call quality through the watch is incredible.

    I have been using the watch for 2 months now and it is excellent.
    Calls are very good!
    Greek menu!
    Excellent GPS!! Accurate measurements in cycling and running and results connection with Strava!
    Good customization in the menu
    The flashlight is a must!
    Heart rate monitor, sleep, stress, oxygen saturation
    In general, all measurements work well, compared to Garmin and iPhone.

    The battery with full use (permanent connection with phone, calls, messages, automatic heart rate measurement every 5 min, stress every 30 min, and oxygen every 10 min, as well as 2 workouts using GPS for a total of 3 hours... 4-6 days!

    At €38, which I bought from abroad, it is amazing!
    DO NOT get it for use in a pool or the sea!

  • With active GPS: Up to 45 hours (enough to record even an entire Ultra race).

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.

20 ATM (200 meters): Diving, deep water activities.

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
30 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.

Fantastic watch for its price
Very honest and does everything, without lagging

The battery just doesn't run out...

As for waterproofing, I just get it wet, I don't need to submerge it completely, so I don't have a full opinion

The watch is very good value for its money. I have paired it with iOS using the Gloryfitpro app. I have also connected this app with Strava so I can view activities like running, etc., with maps. Its battery lasts quite a while. Its design is beautiful. Quite satisfied and I am waiting for the summer to try it out in the sea and also to see its durability over time.

update 8-6-2026. I was very satisfied with the watch until I swam in the sea and the next day I noticed that the watch discharged immediately within about 3 hours.

    It stops recording activity whenever it wants.
    One of the buttons, after 3–4 months of use, has to be pressed harder to activate.
    The compass goes out of alignment very often and needs to be recalibrated.
    The app logs out on its own quite often.
    Many times, even when my heart rate was elevated, the watch showed my resting heart rate—that is, while running, 55 beats per minute.
    If you just want to count steps, it’s OK.
    It’s not worth it, not even from an overseas website where it’s half the price. Better to get a well-known brand.

    It is admittedly a watch with limited capabilities. It can do very specific things, but at this price of 50-70 euros, I don't know if there is really anything better. It is not for swimming in the sea; it is for walking, running, and generally activities on land, and of course connection to a mobile phone for calls, messages, etc. Since what matters to me is battery life, I did a test: operating it almost exclusively as a fitness tracker (step and running tracking) and a recorder of vital signs (heart rate, blood oxygen, stress, sedentary reminder), its battery lasted exactly one month (and 10% was left). I count that as a positive. The fairest thing for this particular watch would be if I could give it 4.5 stars.

    Generally, it is quite good for its money, but it has a very serious issue with its battery life. With almost minimal use and power-consuming settings turned off, it barely lasts 4 days. I would not recommend it to a user who wants it for all-day use in a similar way to a phone. If you use it like a phone, it may even need charging every day.

    I’ve had it for 12 days and it gave up the ghost! While I had been satisfied with its measurements and battery life, one morning the buttons suddenly stopped working and it kept restarting continuously! Too good to be true! If you don’t spend over 300 on a truly waterproof watch for swimming, not diving, and with good measurements, there isn’t one!

    This review is about the colour: Black

    It is a typical Chinese smartwatch, one of those you find for 50 euros.
    In reality it is a clone of the DM58 OEM model, sold under various Chinese brands.
    For the money, it is good.
    Its negative point, classically, like all cheap Chinese watches, is the non-existent vibration. You miss notifications because your wrist does not feel the vibration.

    I regretted buying it.

    As for water resistance, only for showering. Do not swim with the watch.

    This review is about the colour: Black

    UPDATE 05/07/2026: Unfortunately, we drop to 1 star since after just 3 months of use and 4 swims in the sea the watch gave up.
    Coming from other smartwatches, I will say that I was disappointed by this one and had higher expectations.
    The UI freezes quite a bit, making the use of the built-in apps annoying.
    The notifications that come from Messenger, for example, you can rarely read the message since it gives priority to the sender's full name, etc., with the result that you have to manually tap the notification to read it, so the whole point is lost for me personally.
    Positive and nice lens, but in my opinion in the wrong place.
    Respectable battery life with everything on and quite a few notifications, it lasts more than 7 days without a problem.
    Personally, I would recommend going for something else

    Bought almost a month ago, battery lasts 8 days with everything turned off, otherwise sturdy construction, beautiful and good for its price. If it hadn't caused eczema on my hand, probably due to an allergy, I would have kept it, but Huawei is the only option.

    Good but I think there are still some things missing for it to get all 5 stars.
    On the downside, it (probably) doesn't have automatic brightness, you can't connect, for example, all your phone's apps but only some that the app specifies.

    very good, the battery lasts about ten days with mixed use. Very good screen, bright even under the sun. Good microphone and speaker during calls. The only thing I would like is a better charging adapter...but it's okay as long as you make sure that charging has started.

    with full use, battery life is 20 days+
    the box also includes a transparent screen protector!

    This review is about the colour: Black

    For its price, as a beautiful Smartwatch, it is very good. It has quite a few functions. I have no opinion about the accuracy of its measurements. Honestly, it looks a lot like Garmin and the flashlight it has, which cannot be compared in intensity to the €1200 watch, but at night it will help you! The battery definitely lasts 12 days, maybe more with simple use. The speaker is very good. The call quality is very good. For the 80-something euros, I think it's fair. You can also add whatever watch face you want through the app! I think it's a fair purchase!

    Excellent watch, easy to operate from the very first moment. The LED flashlight is very useful. The battery lasts 10 - 12 days with normal use. So far its measurements seem accurate. It is very lightweight and comfortable on the wrist. It is definitely value for money. The call quality through the watch is incredible.

    I have been using the watch for 2 months now and it is excellent.
    Calls are very good!
    Greek menu!
    Excellent GPS!! Accurate measurements in cycling and running and results connection with Strava!
    Good customization in the menu
    The flashlight is a must!
    Heart rate monitor, sleep, stress, oxygen saturation
    In general, all measurements work well, compared to Garmin and iPhone.

    The battery with full use (permanent connection with phone, calls, messages, automatic heart rate measurement every 5 min, stress every 30 min, and oxygen every 10 min, as well as 2 workouts using GPS for a total of 3 hours... 4-6 days!

    At €38, which I bought from abroad, it is amazing!
    DO NOT get it for use in a pool or the sea!

    It really has many and useful features.
    It is very beautiful.
    As long as I have it, it has not presented any problems.
    Very lightweight and comfortable.
    However, I have had it for a month so I do not know its durability over time.
    Due to the many features, it also requires greater ability to assimilate and memory.

    In summary! Owner of Garmin Epix, Fenix 7, Huawei Gt4, Huawei Ultimate, almost all Samsung. I used to mock it, to be honest. The watch does exactly what it promises in terms of battery (very important for me), durability, calls, messages, social. It has everything. China rules! Oh, and it looks much more beautiful than much more expensive ones!
