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 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.

My first watch was the Galaxy Watch 4 and I was pleased, now I've tried the Galaxy Watch 9 and I'm pleasantly surprised. Compared to the previous version, it's lightweight, has a large display, and the apps are fast. The installation went smoothly, thanks in part to having the previous version. The battery life is also great. Compared to the Watch 4, it's thinner and looks elegant on the wrist. So far, it's all been positive. I have a phone, a watch and a washing machine from Samsung, and I'm very, very satisfied. The controls, the installation, everything connects beautifully, a big thumbs up from me 👍👍👍

In my opinion, probably the best price/performance ratio. Sleep coach, heart rate measurement, daily summaries – exactly what you expect from a smartwatch. They fit comfortably and are pleasantly light on the wrist. I use them with a Samsung mobile, some features might be limited when pairing with other brands. The battery, of course, like with other smartwatches, has a capacity of a day and a few hours.
Elegant
convenient
Goes well with smart clothing too, doesn't look like a sports gadget.
The light-coloured strap gets dirty – it needs to be cleaned more often.
