Pixel Watch 3 Review: Strong but Not Perfect
Our full Pixel Watch 3 review after two weeks of testing: measured performance, battery figures, and whether it is worth £349.
Priya Raghunathan
The short version
The Pixel Watch 3 is Google's 2024 entry in a crowded wearables market, and at £349 it is competing against some of the strongest hardware we have tested. After a fortnight of daily use, the headline is straightforward: it delivers a battery that finally lasts a full day.
In a sentence: Buy it for a battery that finally lasts a full day. Think twice if this would bother you daily: domed glass that scratches.
In the hand
There is nothing experimental here, which is mostly to the Pixel Watch 3's credit. The detail worth calling out is that the previous generation could not manage a full waking day. Against the rest of the wearables category it feels considered rather than novel.
How it performs
Our testing runs the same suite on every device so figures stay comparable across years. The figure worth quoting is Rating: 5ATM. That places it comfortably above average for its price bracket.
| Specification | Pixel Watch 3 |
|---|---|
| Display | 45mm AMOLED, 2000 nits |
| Battery | 26h with always-on |
| Sensors | HR, SpO2, ECG, skin temperature |
| Rating | 5ATM |
How we tested
Every figure quoted above comes from the same protocol, run on every unit in this category. This one spent three weeks worn continuously, including overnight. Worn on the non-dominant wrist alongside a chest-strap heart rate monitor and a second reference watch, with all figures logged from the same sessions.
| What we measure | How |
|---|---|
| Heart rate accuracy | Beat-by-beat comparison against the chest strap across steady runs, intervals and weights. |
| GPS accuracy | The same 5km loop, twelve times, compared against a surveyed route. |
| Battery life | A fixed daily pattern — one hour of GPS exercise, always-on display, sleep tracking — run to empty. |
| Sleep tracking | Compared against a manual log of actual sleep and wake times over fourteen nights. |
| Durability | Worn through cooking, washing up and the gym, with no attempt to protect it. |
We deliberately do not report step counts, which every device on the market gets close enough that the differences are noise.
The honest caveat: Wrist-based heart rate is least accurate exactly where people care most — high-intensity intervals.
The strengths
- A battery that finally lasts a full day
- Genuinely useful running form analysis
- The best-looking smartwatch on Android
Taken together, those strengths make it a natural fit for Android users who want a watch that does not look like a fitness tracker.
Where it falls short
- Domed glass that scratches
- Android only
- A Fitbit Premium paywall on some metrics
None of these are dealbreakers on their own. Whether they matter depends entirely on how you intend to use it, which is why the section below matters more than the score.
How it compares
The closest alternatives on price are Oura Ring 4 and Apple Watch Series 11. All three have been through the same tests, so the figures below are directly comparable rather than collected from different reviews.
| Model | Price | Our score | Standout | Weak point |
|---|---|---|---|---|
| Pixel Watch 3 (this review) | £349 | 4 / 5 | A battery that finally lasts a full day | Domed glass that scratches |
| Oura Ring 4 | £349 | 4 / 5 | The most accurate sleep staging we have tested | A mandatory subscription |
| Apple Watch Series 11 | £399 | 4 / 5 | The first genuine battery improvement in three generations | IPhone only |
Nothing at this price scored higher in our testing, which is the strongest argument for the Pixel Watch 3.
Is it worth the money?
At £349 the Pixel Watch 3 undercuts the category average of £365 by £16, against an average score of 3.9 out of 5 across the wearables we have tested. Its own 4 works out at roughly £87 per point. That is the straightforward case: above-average result, below-average price.
If the budget is the binding constraint, the Fitbit Charge 6 at £139 is the floor we would still recommend — below that the compromises stop being ones you can live with.
Daily use
Two weeks in, the figure that stopped mattering was display — 45mm AMOLED, 2000 nits is more than adequate and you forget about it by the third day. What kept surfacing instead was that domed glass that scratches, which is easy to shrug off in a spec comparison and harder to ignore at 6pm on a Friday. On the other side, the previous generation could not manage a full waking day turns out to be the sort of detail you only appreciate after living with the alternative.
Who this is for
Buy the Pixel Watch 3 if you are Android users who want a watch that does not look like a fitness tracker. Skip it if this is something you would notice every day: domed glass that scratches.
Buy it if:
- Android users who want a watch that does not look like a fitness tracker
- You want a battery that finally lasts a full day
- You value genuinely useful running form analysis
Skip it if:
- You need domed glass that scratches to be a solved problem
- The Oura Ring 4 at £349 already covers what you need
- You upgraded within the last two years — the gap is not worth the outlay
Verdict
Buy it for a battery that finally lasts a full day. Think twice if this would bother you daily: domed glass that scratches.
Score: 4 / 5 · £349 at the time of writing.
Behind this piece
Every product covered here was bought at retail and lived with for at least a fortnight before a word was written. Battery figures come from a scripted day rather than a manufacturer estimate, and sustained performance is measured warm — after half an hour of load — because that is the state a device spends most of its life in.
Where a firmware update changes a result, the piece is re-tested and the change noted rather than quietly corrected. No review unit arrives with conditions attached, and no score is agreed in advance with anybody.
Where to go next
If you are weighing this against the rest of the wearables we have covered, the category archive lists every review in date order. The closest comparisons we have published are Pixel Watch 3 vs Oura Ring 4: Same Money, Different Priorities and Pixel Watch 3: Battery Draining Faster Than It Should.
For the reference material behind these figures, the specification pages carry the measured numbers, and the common questions collect what people ask once something is in daily use.
