Side-by-Side Comparison
| Spec | Google Pixel Watch 5 (41mm, Wi-Fi) | OnePlus Watch 3 43mm |
|---|---|---|
| Price | $399.99 | $249.99 |
| Release Year | 2026 | 2025 |
| Phone Compatibility | Android only — Google requires a compatible phone running Android 12.0 or newer. iPhone is explicitly not supported. Unlike Samsung, Google does not gate health features to its own phones: the Pixel Watch works the same on a Samsung or OnePlus handset as on a Pixel. | Android only in practice. OnePlus markets it as a Wear OS watch requiring Android; the Amazon listing title states in plain text 'not Compatible with iOS'. Sources conflict: Smartprix's spec sheet lists 'Android 9.0+ and iOS', which contradicts both OnePlus and the retail listing — treat iOS as unsupported. |
| Claimed Battery Life (hrs) | 40 | 60✓ |
| What the Battery Claim Assumes | Google's 40 h claim is for the 41mm in its default mode; droid-life reports a 40-72 h range across sizes and power modes, so the top of that range needs the larger 45mm and a battery-saver profile. Google's marketing does not state whether the always-on display is enabled for the claim. LTE and continuous GPS both cut it further. | OnePlus's 60 h smart-mode figure assumes the low-power RTOS co-processor handling the always-on layer and no heavy GPS. Power Saver mode extends it further but drops Wear OS features; continuous GPS workouts and LTE-style always-connected use are not part of the claim. |
| Case Size (mm) | 41 | 43 |
| Display | Actua 360 domed OLED under Gorilla Glass, up to 3000 nits | 1.32-inch LTPO AMOLED, 466x466. Peak brightness is not published by OnePlus. |
| Operating System | Wear OS 7 with Gemini | Wear OS 5 by Google plus RTOS dual-engine |
| Third-Party Apps | Google Play Store on the watch — the reference Wear OS implementation, first to every Wear OS release | Google Play Store on the watch — a full Wear OS catalogue, unusual at this price |
| Health Features Enabled in the US | Live now: ECG with AFib detection, Loss of Pulse Detection with emergency calling (FDA-cleared), heart rate variability, SpO2, breathing rate and skin temperature. The two headline launch features — blood pressure trends and insulin resistance trends — were announced as 'coming this fall', i.e. NOT enabled on day one, and Google has not published FDA clearance for either. | Heart rate, SpO2, skin temperature, stress and sleep — all wellness-grade. There is NO ECG and no FDA-cleared feature of any kind on this model in the US; the health story is the weakest of any Wear OS watch here. |
| Subscription Wall | The Fitbit app is now the Google Health app. Google Health Premium (3 months included) gates Gemini coaching, adaptive fitness plans, sleep guidance and proactive insights; the raw metrics stay free. | None. OHealth is free and does not paywall any metric. |
| LTE Option | Separate SKU and separate ASIN: LTE adds $100 (41mm LTE $499, 45mm LTE $529). Google Fi includes 2 years of data on the LTE model, but the watch does not support calling on it. | No LTE variant is sold in the US — the OnePlus Watch 3 43mm is Bluetooth/Wi-Fi only. |
| Water & Dust Rating | IP68 water and dust resistant (no ATM swim depth rating published) | 5 ATM (50 m) plus IP68 |
| Battery Replacement | Google does not offer a battery-replacement service for Pixel Watch; earlier Pixel Watch generations were widely reported as non-repairable whole-unit swaps. | OnePlus does not publish a consumer battery-replacement service for the Watch 3. |
| Warranty | 12 months | 12 months |
| Colors | Obsidian, Fog, Canyon, Olive | Black Steel, Silver Steel |
Category Scores
Battery Life
The OnePlus Watch 3 43mm leads clearly here, 8.2 against 6.8 — a 1.4-point margin on real endurance between charges, judged against what the claim actually assumes rather than the headline number. If that is what you are buying for, the Google Pixel Watch 5 (41mm, Wi-Fi) does not close the gap elsewhere.
Health Tracking
The Google Pixel Watch 5 (41mm, Wi-Fi) leads clearly here, 8.4 against 6.0 — a 2.4-point margin on depth of heart, sleep and body metrics that are genuinely enabled and cleared for use in the US. If that is what you are buying for, the OnePlus Watch 3 43mm does not close the gap elsewhere.
Fitness & GPS
The Google Pixel Watch 5 (41mm, Wi-Fi) leads clearly here, 8.6 against 7.0 — a 1.6-point margin on workout tracking, GPS accuracy, sport modes and training analysis. If that is what you are buying for, the OnePlus Watch 3 43mm does not close the gap elsewhere.
Ecosystem Freedom
The Google Pixel Watch 5 (41mm, Wi-Fi) and OnePlus Watch 3 43mm are level here, at 3.0/10 each. the category's trap dimension: how much of the watch still works on a phone other than the maker's own. 10 means full parity on iOS and Android; 1 means one phone brand or nothing is not what separates these two — look to the categories where the scores diverge.
App Ecosystem
The Google Pixel Watch 5 (41mm, Wi-Fi) leads clearly here, 8.5 against 8.0 — a 0.5-point margin on whether there is a real third-party app store on the wrist or a handful of proprietary mini-apps. If that is what you are buying for, the OnePlus Watch 3 43mm does not close the gap elsewhere.
Display
The Google Pixel Watch 5 (41mm, Wi-Fi) leads clearly here, 9.2 against 8.2 — a 1.0-point margin on panel type, brightness, always-on behaviour and legibility in sunlight. If that is what you are buying for, the OnePlus Watch 3 43mm does not close the gap elsewhere.
Build & Durability
The OnePlus Watch 3 43mm is marginally ahead, 8.2 to 7.8. A gap this small rarely decides a purchase on its own, though it counts if case and glass materials, water and dust ratings, and how well it survives daily wear is your priority.
Value
The OnePlus Watch 3 43mm leads clearly here, 8.4 against 7.2 — a 1.2-point margin on what you get for the money once LTE upcharges and subscriptions are counted in. If that is what you are buying for, the Google Pixel Watch 5 (41mm, Wi-Fi) does not close the gap elsewhere.

Pros & Cons
Google Pixel Watch 5 (41mm, Wi-Fi)
Pros
- +Health features are not gated to Google's own phone — a real advantage over Galaxy Watch on a non-Samsung Android

- +15 hours of battery from a 15-minute charge is the best top-up rate in the category
Cons
- −Blood pressure and insulin resistance — the two features the launch was built on — were 'coming this fall', not shipping at launch, with no published FDA clearance
- −No iPhone support at all
- −LTE is a $100 upcharge and a different ASIN, and it still cannot make calls over LTE on Google Fi's included plan
- −IP68 only, with no ATM swim depth rating, versus 5 ATM on nearly everything else here
- −No battery replacement path from Google
OnePlus Watch 3 43mm
Pros
- +60 hours of real Wear OS battery life — two and a half times a Galaxy Watch9

- −Android only; the Amazon listing says so in the product title
- −No LTE variant sold in the US
- −OnePlus's own store price has drifted around ($270 at last check versus $249.99 on Amazon) — shop the ASIN, not the brand site
