I bought the watch for my girlfriend in the beige colour and she's very happy with the choice. She most appreciates the lightning-fast speed and the overall responsiveness of the system. The display is perfectly readable even in direct sunlight. The only minor drawback is the battery life, which could be a little longer. Otherwise, it's great!
We have a Samsung Galaxy Watch 6 Classic and a Samsung Galaxy Watch Active2 at home. So the Samsung Galaxy Watch 9 40mm was a replacement for the mentioned Active2, bought for my wife. The watch has a nice and subtle design, and it fits the wrist perfectly. The body of the watch is really thin and sits nicely on a woman's wrist. Since we use Samsung watches at home, the transition to the new model in the phone app was quick and without any problems.
I bought the watch as a birthday present for my mum, who previously used a Samsung Galaxy Watch FE. She says her Samsung Galaxy Watch 9 lasts much longer on a single charge than the previous one. While the old one lasted less than a day, this one easily lasts a full day without any issues, even under heavy use. The system for clicking the strap into the watch is super simple, and the selection of different types of straps for this watch is also diverse. My mum chose an olive fabric strap for it because her wrist would get sweaty under the silicone one, but she still uses the silicone one for swimming. She also changes the watch face variations and customisation options depending on whether she's at work or relaxing at home.
The watch has a very bright and high-contrast display, so it's always perfectly visible, even outdoors in direct sunlight. It fits her wrist beautifully. I think a larger one would have been too bulky for her, and that 40mm is more than enough – compared to 44mm, it's a noticeable difference on my mum's wrist. The virtual bezel works better and more smoothly than on previous models. The user interface is really intuitive, so my mum can use it with absolutely no problems. She's learned to make calls easily with clear sound, which is very practical at home. She also uses it for sports and likes to keep track of her steps or heart rate. She also commonly uses it as a timer when cooking, for example. In short, she's absolutely delighted with the gift, and it makes me happy that the watch makes her everyday life so much easier and more enjoyable.
I bought the watch as a gift. They really liked it, everything works brilliantly, the display is fast and responds well to touch. The size fits the wrist perfectly and the watch looks great on. So far I'm very satisfied and can't see any faults with it.
I bought the watch for my mum, who says about it: “As a former user of a lower-end model, I have to say that the Galaxy Watch9 is very well made. It's fast, clear, and easy to use. I appreciate the excellent synchronisation with my phone and the clear data for monitoring vitals, which can also serve as a useful preventative health check. The downsides are the shorter strap and the currently limited choice of colours. Otherwise, I'm very satisfied and would definitely recommend the watch.”
I bought this watch as a replacement for my older Watch5 and I must say, it's a huge leap forward. The biggest difference for me is the display and the speed. With the older Watch5, I had trouble reading messages in the sun and the system would sometimes freeze on me. The Watch9 is incredibly bright, so I can see it perfectly even in direct sunlight. The response is lightning-fast, everything runs absolutely smoothly and nothing lags.
The larger storage is also great, I've loaded my songs onto it. The step and sleep tracking seem more accurate to me and it looks really great on my wrist thanks to the thinner bezels.
I've been wearing the Galaxy Watch9 for just under a month, for about 14 days, from morning till night. The display is the first thing that catches your eye: it's beautifully bright, sharp, and readable even outside in the sun, and rotating via the bezel is addictively smooth. I appreciate it most on walks — the step count and distance walked are accurate, the heart rate measurement is reliable, and it's nice to have an immediate overview of how far I've walked after a longer outing. The sleep monitoring also works brilliantly; in the morning, I can see straight away how well I've slept. It sits comfortably on the wrist, is surprisingly light, and doesn't get in the way even when worn all day. Connecting to a Samsung phone is completely seamless, with notifications arriving instantly.

I've only been wearing the watch for a few days, but I can already say it's a step up from my old smartwatch. The first thing that surprised me on these sunny days is the excellent readability of the display. The watch is packed with features – ECG measurement, blood oxygen (SpO2), and even blood pressure. The Energy Score feature is fantastic; it tells me quite accurately every morning how much I've recovered overnight. The only thing I haven't fully tested yet is making payments, but I'm sure that will be problem-free too. For me, the Watch9 is the best replacement.
Compared to my old Samsung Galaxy Watch 4, I'm thrilled!

I upgraded to the Galaxy Watch 9 from the Galaxy Watch 6. There's definitely a noticeable improvement in lots of things. The display is beautifully clear. The system is smooth and fast. Great connection with my Samsung S25 Ultra phone (the ability to control the camera from your wrist). Battery life is good so far, lasts about 1.5 days. What I'm quite annoyed about is the charger compatibility. I had chargers everywhere, but with the GW9, only the original charger that came with the watch will charge it.
The only compatible charger is the original one
