As always, well-made, and the ergonomics of the small model are perfect. The protective film was applied acceptably by the seller, but you could probably do a better job yourself. The Galaxy Watch9 is light, thin, and very comfortable on the wrist. The controls are responsive (as you'd expect with a 3nm chip), we'll see how often it needs restarting. Still no dedicated torch, but 3000 nits will probably solve most situations. It gets as warm as the Watch8 when charging, but at least the chargers are compatible. I guessed the strap size right, but only just – it would be good to have an option with some measuring guide, though I'll be using my other trusty one from the Watch8 anyway. Can't wait for it to have respiratory or cardiac arrest detection, even if it's unofficial.
and the compact 40mm are very usable
display (+torch) is just as good as the Watch8
only a minor change from the Watch8

I wear the watch pretty much non-stop, and the main thing I have to praise is the weight. You can barely feel the 40mm on your wrist; after a few days, you stop noticing it, even when sleeping. In terms of looks, they're discreet — the black version doesn't come across as a 'gadget', so I have no problem wearing it with more formal clothing. The display is brilliant. It's readable even in direct sunlight; I don't have to shield it with my hand or raise my wrist to my eyes, I just look and I can see. The only thing I would criticise is the battery life. I charge it every morning, which I personally don't mind — it's become part of my routine, and I don't think about it. But anyone expecting to throw the watch on the charger once over the weekend and be done with it will probably be disappointed. You have to be prepared for daily charging.

The switch from the Galaxy Watch 46mm (gen1) to this is a really significant one. I'll overlook the battery life, which isn't the best (my old ones lasted 4 days), but on the other hand, I'm happy with the new OS thanks to the wider app support. My main reason, however, was the health and monitoring features, which are beyond comparison, and the amount of information you suddenly have available is brilliant. The new feature for analysing them looks very good.

I'm thrilled with the Samsung Galaxy Watch 9 in black. It's fast, has a premium build quality and very good battery life. I also appreciate the significantly more advanced Gemini assistant, which responds quickly and makes the watch feel much smarter. The strap is super durable for exercise (black is more elegant than white). Samsung Health and the huge selection of different exercises are also great. Simply I❤️Galaxy

The watch may only offer about one day of battery life, but otherwise, it has everything I need from a smartwatch. It monitors health data, measures sleep, and accurately auto-detects different types of exercise. Pairing with my Galaxy S25 Ultra was quick and trouble-free. I was also pleasantly surprised by the sleep tracking. I fell asleep for about 40 minutes after lunch, and the watch recognised I was sleeping on its own, even though it was just a short nap. So far, I'm very satisfied with them.
They do everything I wanted for monitoring health, exercise and even sleep.
The battery lasts about one day, but that's a minor detail.

I've been wearing the watch for about 10 days. Despite the mentioned shortcomings, I'm happy with it and it makes me happy.
Nice sporty look
lots of new features (sport/health indicators/guidance towards a healthier lifestyle). matches the description
slightly longer battery life than the older model (in my case, about half a day)
Reminds you to stretch or get back to an activity after a long period of inactivity or working at the PC
more custom settings and configurations
The battery life could be at least 1–2 days longer
price
I would welcome more types and colour shades of straps to swap for different occasions.

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.
