According to our smartwatch expert
With the Samsung Galaxy Watch 8 Dark Gray 40mm, you get an extensive overview of your health and always have an AI assistant with you. Thanks to the watch, you'll know how you sleep, what your stress level is, and what your stamina is, among other things. That way, you can improve your mental and physical health. For example, your ability to sleep or concentrate. The smartwatch is slimmer than its predecessor, so it fits your wrist better and the health readings are even more accurate. With the AI assistant Gemini, you can make your life easier. Tell the watch on which day you have an appointment and it'll put it in your calendar for you, for example. The battery of the Watch 8 lasts 1.5 days with average use.
This watch is recommended for a wrist circumference of 13 to 15cm.
Note: a charger isn't included. Want to charge the watch via a socket? Use the charger of your smartphone or order a separate charger.

The Galaxy Watch 8 is a stylish smartwatch with a minimalist design. Thanks to its extensive sleep features, I get tips to improve my sleep, and the running coach helps me improve my fitness. Unfortunately, the watch doesn't last long, with a battery life of 1 to 2 days.
Lightweight and minimalist
The watch is light and barely noticeable on my wrist. The case is thinner than its predecessor, making it a better fit. For this review, I'm wearing the 44-millimeter version. My wrist circumference is 17 centimeters, and the watch fits comfortably.
Easy-to-read screen
The screen is much brighter than that of its predecessor, the Watch 7. Even outdoors in bright sunlight, everything is clearly visible. The colors are vibrant and the image is sharp. The screen responds quickly, and I don't experience any delays when scrolling or switching between apps.
Aware of my sleep routine This watch gives me a lot of insight into my sleep. For example, I know exactly which sleep phase I'm in. The watch combines all my sleep data and also provides advice. In the evening, for example, I get a notification with my ideal bedtime. I have to wear the watch while sleeping for seven days before I get more insight. This feature makes me more aware of my sleep routine.
Personalized running schedule and coaching I've just started running, so a little guidance is helpful. Before I receive a schedule, I have to complete a 12-minute test. Based on that test, I get a personalized training plan. Sometimes it's an interval workout, sometimes a long run. The different workouts make running more enjoyable. After each workout, I get a detailed overview of my performance, which is motivating.
Voice commands with Gemini I have access to Gemini through the watch, and it works very smoothly. I only have to ask a question, and I get an answer within seconds. I also use it to respond to incoming messages. I just have to say what I want to say and Gemini gives me a suggestion.

For me, it's an upgrade from Watch 4. There are improvements now, but nothing truly spectacular. For example, this watch measures my home temperature, but nowhere (understandably) does it explain what I'm supposed to do with it. Also (and I find this really annoying) it doesn't mention that some of the wireless chargers are now useless with this watch, because the shape of the watch strap prevents the watch from being placed flat on the charger. Quite annoying.

Nice design, only the battery life is a bit short, but I think you can probably extend it by limiting the number of notifications.
