Whether you're playing sports, at work or in your free time, the HUAWEI Watch 4 Pro Space seems to provide stylish and functional support in every situation. We've subjected it to a detailed test - and here's our conclusion.
tl; dr: Overall, the HUAWEI Watch 4 Pro Space Edition really impressed me. The high-quality design, robust materials and numerous advanced functions make this watch one of the best smartwatches on the market for me. Particularly noteworthy are the long battery life and the extensive health and fitness functions, which I have hardly found in this form on any other smartwatch.
For anyone who values quality and functionality, the HUAWEI Watch 4 Pro Space Edition is an excellent choice. Not only does it meet all the expectations of a modern smartwatch, it also offers many extras that make it an indispensable companion in everyday life.
Design and build quality
When I first looked at the HUAWEI Watch 4 Pro Space Edition, I was immediately impressed. The DLC titanium casing, which is normally used in aerospace, not only gives the watch a classy look, but also ensures exceptional durability. The resistance to scratches and wear is really impressive. HUAWEI has not compromised here.promade a mistake.
A real highlight is the watch face specially designed for this model, called “Space Journey”. It depicts a rocket engine and the animation that appears when you open the watch face is simply fascinating and fits perfectly with the theme of the watch.
The back made of high-quality ceramic is also a plus point. It feels comfortable on the skin and improves the sensory properties of the watch. The grey titanium strap complements the elegant design and is also very comfortable to wear. With dimensions of 49,1 x 49,1 x 12,9 mm and a weight of around 68 grams without strap, the watch looks good on my wrist. proportioned and feels very pleasant despite its size.
Display and user interface
I was immediately impressed by the 1,5-inch (3,81 cm) LTPO AMOLED color display on the HUAWEI Watch 4 Pro Space Edition. With a resolution of 466 x 466 pixels and a pixel density of 310 ppi, it offers outstanding sharpness and brilliant colors. The display remains easy to read even in direct sunlight - a big advantage if you spend a lot of time outdoors. The LTPO technology also ensures dynamic adjustment of the refresh rate, which both improves the user experience and optimizes battery life.
The user interface is impressive due to its intuitiveness and fluidity. With the home button, which also functions as a rotating crown, and the side button, navigating through the menus is child's play. The controls themselves are also responsive and the buttons offer a pleasant pressure point, which makes the entire operation particularly comfortable.
I particularly liked the option of customizing the watch to my preferences with different watch faces and widgets. This is not a given with smartwatches, and I have the feeling that HUAWEI is really leading the way here. If there are similar customization options for other models such as the Apple Watch, please correct me - I have only tested an Apple Watch so far. This flexibility makes the HUAWEI Watch 4 Pro Space Edition an individual companion that is perfectly tailored to my needs both visually and functionally.
functions and sensors
The HUAWEI Watch 4 Pro Space Edition really impressed me with its variety of sensors. In addition to the usual ones like an accelerometer and a gyroscope, there is also a compass, an optical heart rate sensor, an ambient light sensor, a barometer, a temperature sensor, and an ECG and depth sensor. These sensors allow for comprehensive health monitoring and precise recording of my activities.

I find the ECG sensor particularly useful. It allows me to record electrocardiograms and obtain valuable information about my heart health. This function is particularly helpful if, like me, you have to monitor your heart rate regularly and want to detect possible irregularities early on. Another plus point is the ability to measure arterial stiffness - particularly useful for someone like me who has smoked for a long time or is struggling with weight. There is certainly a risk of the arteries closing off. I can email the data to my doctor directly from the app, which is very practical.
The depth sensor is particularly interesting for divers, as the watch supports free diving up to 30 meters. A small note: salt water can make the seals brittle over time, so you should rinse the watch thoroughly with fresh water after contact with sea water.
The HUAWEI Watch 4 Pro Space Edition is also well equipped when it comes to connectivity. With NFC and Bluetooth 5.2, it offers a stable and energy-efficient connection to other devices. Speakers and microphones are integrated so you can answer calls directly on the watch. The watch is also eSIM-capable, which means you can leave your smartphone at home sometimes.
battery life and charging function
The battery life of the HUAWEI Watch 4 Pro Space Edition didn't really surprise me - and I mean that in a good way. I'm just used to HUAWEI products offering strong performance. 4,5 days in standard mode is now standard for me and I find that impressive, especially compared to other smartwatches in this class.
In ultra-long battery life mode, the watch can even last up to 12 days, which is particularly useful if you are on the go for longer periods or are active outdoors a lot. If you deactivate energy-intensive functions, the battery life can even be extended to up to 21 days. Personally, I end up with the mentioned 4,5 days with intensive use, and I think that's perfectly fine.
Wireless charging is convenient and straightforward. The included charging station works reliably and charges the watch quickly - that's really practical in everyday life. HUAWEI has once again done a solid job here.
Waterproof and robust
The HUAWEI Watch 4 Pro Space Edition is water resistant up to 50 meters, meeting the ISO 22810:2010 standard, making it ideal for swimmers and water sports enthusiasts. It also meets the requirements of the EN 13319 standard for diving accessories and supports free diving up to 30 meters deep. This robustness is truly impressive and is thanks to HUAWEI's high-quality materials and precise workmanship.

However, you should note that the watch is not suitable for scuba diving or technical diving. Hot springs, saunas or activities with high water pressure could also affect the water resistance. After being in salt water, I always rinse the watch thoroughly with fresh water and dry it well to protect the seals. This will hopefully keep the watch in top condition for a long time.
Compatibility and system requirements
The HUAWEI Watch 4 Pro Space Edition is compatible with both Android and iOS devices, which I think is really great. The system requirements are quite moderate: Android 8.0 or higher or iOS 13.0 or higher. Setting it up and synchronizing it with the HUAWEI Health app went smoothly for me. The app is clear and offers many customization and monitoring options. I was particularly impressed by the detailed analysis of the recorded data.
