Choose the Samsung Galaxy Watch8 if you use a Samsung Galaxy phone or want Samsung Health; choose the Google Pixel Watch 3 if you prefer Google and Fitbit services or need a watch whose stated Android compatibility starts at Android 10. Neither is a universal winner: phone compatibility, wrist fit, LTE needs and the apps you want matter more than a spec-sheet sweep. This comparison is current to October 7, 2026; Google’s current comparison page also lists the newer Pixel Watch 4, so Pixel Watch 3 is not Google’s latest generation.
At a glance: which watch fits your needs?
| Choose | If this matters most | What to check |
|---|---|---|
| Samsung Galaxy Watch8 | You use a Samsung Galaxy phone or want Samsung Health and Galaxy Wearable. | Samsung’s US compatibility wording specifies Galaxy phones on Android 12 or higher. Check the requirements for the features you plan to use. |
| Google Pixel Watch 3 | You prefer Google and Fitbit services, or want the broader stated Android-version threshold. | Google says it works with most Android phones on Android 10 or newer; a Google Account and Pixel Watch app are required. Some functions require the Fitbit app and/or a paid subscription. |
| Either | You mainly need a smartwatch for notifications, activity tracking and everyday use. | Compare case fit, Bluetooth versus LTE, current local pricing, and the specific health features available with your phone and in your region. |
Samsung’s US and UK pages describe compatibility differently: its US page specifies Samsung Galaxy phones running Android 12 or higher, while its UK specification says smartphones running Android 12 or higher. Google’s Pixel Watch 3 specifications say “Works with most phones running on Android 10.0 or newer.” Those are manufacturer requirements, not a guarantee that every feature works on every compatible phone or in every country.

Phone compatibility and app ecosystem
Galaxy Watch8: best aligned with Samsung’s ecosystem
Samsung points buyers to Galaxy Wearable and Samsung Health. If your phone is a Samsung Galaxy and you already use those apps, the Watch8 is the more direct fit. Samsung’s regional pages do not establish that all Watch8 features are available with every Android phone, so confirm the requirements for any particular feature before buying. See Samsung’s US Galaxy Watch8 page and UK specification.

Pixel Watch 3: Google and Fitbit services
Pixel Watch 3 is a stronger candidate if Google and Fitbit services are the ecosystem you want. Google notes that some functions require the Fitbit app and/or a paid subscription; requirements can vary by feature and region. Review the Pixel Watch 3 announcement and the technical requirements before treating any health or software feature as included for your situation.

Sizes and fit: 40/44 mm or 41/45 mm?
Galaxy Watch8 is offered in 40 mm and 44 mm sizes; Pixel Watch 3 in 41 mm and 45 mm. These nominal case measurements are close, but they do not establish which watch will feel better on your wrist. Case shape, band fit and personal preference matter, so compare the models on your wrist if possible rather than choosing by millimetres alone. Specifications are listed by Samsung UK and Google.
Battery life: manufacturer estimates, not a head-to-head test
Samsung says both Galaxy Watch8 sizes offer up to 30 hours with Always On Display enabled. Google lists up to 24 hours with Always-on display for Pixel Watch 3, or up to 36 hours in Battery Saver mode. These are estimates from the manufacturers under different stated modes, not results from a controlled, same-settings comparison; they do not establish which watch lasts longer in everyday use. Google says runtime depends on enabled features, use, environment and other factors, and Samsung also describes usage time as variable. See Samsung’s specification and Google’s technical specification.

Bluetooth or LTE: decide whether you need phone-free connectivity
Both watches have Bluetooth and LTE versions. LTE can support connected use away from the phone, but the exact watch variant, carrier support and any related service conditions or costs need checking before purchase. Google’s technical listing also includes Bluetooth, Wi-Fi and NFC; confirm the exact Pixel Watch 3 SKU and regional availability. Samsung lists Bluetooth and LTE models in its Galaxy Watch8 specification.

Pick Galaxy Watch8 if Samsung is central to your setup
Start with the Watch8 if you use a Samsung Galaxy handset, rely on Samsung Health or want to stay within Samsung’s wearable ecosystem. Confirm that your phone and region support the particular features you intend to use, then choose the 40 mm or 44 mm case and Bluetooth or LTE.

Pick Pixel Watch 3 if Google/Fitbit or Android 10 compatibility is the draw
Evaluate Pixel Watch 3 if Google and Fitbit integration suits you, or if the stated Android 10-or-newer threshold better matches your phone. Check the Google Account, Pixel Watch app and Fitbit-related requirements for your planned use, along with the exact variant and carrier support if you want LTE.
Compare current offers before deciding on value
Because the watches are from different launch generations and only Samsung’s dated US MSRP figures are established here, a fixed price verdict would be unreliable. Compare current prices in your region for the same size and connectivity type. As of October 7, 2026, Google’s comparison page lists Pixel Watch 4 alongside Pixel Watch 3, so consider whether buying the older Pixel model makes sense at its live price: Google’s current product comparison.
