According to our smartwatch expert
The Samsung Galaxy Watch Ultra (2025) 4G Titanium White 47mm is an outdoor watch that you can achieve your workout goals and improve your performance with. You get extensive insight into both your physical and mental health. For example, you can get to know more about your sleep pattern and stress level. You also receive personal workout advice for running a marathon, for example. The watch is made of strong titanium and sapphire glass. This means the Watch Ultra can take a hit as well as withstand extreme cold and heights. Thanks to the built-in eSIM, you can call and text with this smartwatch even when you don't have your smartphone with you. You do need a separate 4G eSIM data plan for this. The storage is twice as large as that of its predecessor, so you can store even more music on the 64GB storage. With average use, the battery lasts 2 to 3 days.
This watch is recommended for a wrist circumference of 17 to 19cm.
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.

I used to have a Galaxy Watch 5 Pro. It's now 3.5 years old, and I thought it was time to look for a new one. What strikes me most is that there's very little new. The software has only been updated in terms of widgets, which are actually less extensive and worse for my liking. The hardware is also virtually nothing new. The battery is exactly the same size (590 mAh), and the GW5pro already had a sufficiently bright screen. It also had dual-band GPS and all that. The only new features are the siren and the faster chip. The siren is truly useless, because if you're the kind of adventurer (which Samsung wanted to reach with this watch), you'll sometimes be without power for more than two days in the mountains, and then the battery is completely useless. You can compare this to driving around New York in a jeep; it might look nice and cool, but it's completely useless. The siren also makes it look bigger, so it gets caught on your jacket and such, making it difficult to remove from under a sweater. I'm returning this watch next week because I'm so disappointed. It costs a fortune but offers virtually no new features. So I don't recommend it unless you have a lot of money to burn.

It does exactly what it promises. I have a heart rate monitor and can track my weight. The battery is still too low.

I've used them at the gym, I wear them while sleeping to track my sleep, and I've showered with them without any issues. I haven't found any negatives yet.
