Galaxy Watch Ultra2 review: the sports watch that has to justify the wrist

Samsung’s Watch Ultra line exists because the ordinary Galaxy Watch is a very good notification disk, and a slice of buyers wanted something that could go on a wet long run without begging for a charger at the office. The Ultra2 keeps that job. The official UK RRP is £649. That is phone money. It has to be more than a brighter screen on your wrist.

Who it is for

It is for someone who already uses a recent Samsung phone, trains often enough to care about GPS that does not wander off a towpath, and is tired of charging a watch on the same rhythm as their handset. The battery is the product. Multi-day wear, with the always-on display used honestly rather than switched off to win a spec-sheet argument, is the bar the Ultra2 was built to clear.

It is not for iPhone owners. Samsung’s watch stacks its useful features on Galaxy phones. Buying it as a compromise is how you end up with a £649 step counter. Apple Watch remains the answer in that house, or no watch at all.

The size problem

Ultra watches are large. Samsung’s is a block on a slim wrist and a tool on a bigger one. This is not a review that will tell you the Ultra2 “wears smaller” as a consolation. Go to a shop. Put it on over the cuff you actually wear to work. If you are already negotiating with yourself in the mirror, buy the standard Galaxy Watch and keep the difference.

Bands matter more than the launch photos suggest. A sport strap in November rain is a different object from the one in the press picture. Budget for the strap you will not hate in February.

Sport, sleep and the data you will ignore

GPS on recent Ultras is good enough for road running, rows and the sort of ride that does not require a cycling computer. Dual-frequency is the phrase to look for on the model you buy; it is what keeps a trace from cutting corners through buildings. We are not going to invent a metre-level error from a single Saturday. If your routes are under trees and between tower blocks, compare a trace with a phone app you already trust before you depend on it for a race.

Sleep tracking is the feature people open for a week and then only when they feel awful. That is fine. The score is a prompt, not a grade. What is useful is the trend: bedtime drifting, recovery looking worse after a week of short nights. What is not useful is treating a single ‘72’ as a reason to cancel a morning.

Phone dependency

An Ultra2 without a Galaxy phone nearby is a watch that tells the time and tracks a run. The replies, the ECG-style features where Samsung has cleared them, and the tight notification actions live in the phone relationship. Check which health features are enabled in the UK on the exact model. Regulatory clearance is not a global switch, and a feature in a US keynote is not a feature in a UK box.

The money

£649 for the 47mm LTE model only makes sense if the battery and the training tools are the reason. If you want notifications and a contactless payment, the standard Galaxy Watch is the grown-up purchase. If you want a training watch and you do not own a Samsung phone, look at a Garmin before you look at this. Different religion, often a better one for people who run more than they text.

The Ultra2 earns a 4 because it does the job it claims, on the wrist it fits, next to the phone it expects. It does not earn more, because a lot of buyers will wear it twice and go back to a lighter watch they forget to take off.
