Pixel Watch 4 vs Galaxy Watch 8: Price and Specs Compared

Samsung's Galaxy Watch 8 starts at $299.99 and Google's Pixel Watch 4 starts at $349.99, and the $50 gap only widens once you add LTE or the larger case — so the right pick mostly comes down to battery life, safety features and which phone is in your pocket. Both watches launched within weeks of each other, both run on Android phones only, and both now carry Google's Gemini assistant, which makes this one of the closest smartwatch match-ups of the year.

Below is a full breakdown of official pricing, specs and features for the Google Pixel Watch 4 and the Samsung Galaxy Watch 8, pulled directly from Google's and Samsung's own product pages.

Price: Galaxy Watch 8 undercuts the Pixel Watch 4

On Samsung's own store, the Galaxy Watch 8 starts at $299.99 for the 40mm Bluetooth model and climbs to $329.99 for 44mm Bluetooth, $349.99 for 40mm LTE and $379.99 for 44mm LTE. Google's store lists the Pixel Watch 4 starting at $349.99 for the 41mm Wi-Fi/Bluetooth model — already $50 above Samsung's entry price — with pricing rising for the larger 45mm case and for the LTE-connected versions. At every matching tier (same case size, same connectivity type), the Galaxy Watch 8 is the cheaper watch.

That price gap buys Samsung some real headroom, since the Galaxy Watch 8's $299.99 base model already includes dual-frequency GPS and a bright 3,000-nit display — features Google only offers on the pricier Pixel Watch 4. Google also lists a financing option on its Pixel Watch 4 page, breaking the 41mm Wi-Fi model into 12 monthly payments of $29.17, which is worth factoring in if you're weighing the two watches on monthly cost rather than sticker price.

Design, sizes and colors

The Galaxy Watch 8 comes in 40mm and 44mm Armor Aluminum cases finished in Silver or Graphite, and Samsung says the redesigned "cushion" shape brings the body down to a slim 8.6mm thick. The Pixel Watch 4 keeps Google's signature domed, circular Actua 360 display in 41mm and 45mm aluminum cases, with housings built from 100% recycled aluminum. Color and band pairings include Polished Silver with an Iris or Porcelain Active Band, Satin Moonstone with a Moonstone band, Champagne Gold with a Lemongrass band, and Matte Black with an Obsidian band.

On weight, Google publishes exact figures: the 41mm Pixel Watch 4 weighs 31.0g and the 45mm weighs 36.7g, both without the band, and both measure 12.3mm tall. Samsung doesn't publish matching case-only weights for the Galaxy Watch 8 on its spec sheet, but does confirm the 8.6mm case thickness across both sizes.

Band fit differs by case size on the Pixel Watch 4: Google includes small and large Active Bands with both models, but the ranges shift with the case — the 41mm's small band fits wrists from 130–175mm, while the 45mm's small band fits 150–185mm. Samsung, meanwhile, says the Galaxy Watch 8 uses an "upgraded Dynamic Lug System" this generation, part of the redesigned cushion-shaped case Samsung introduced with this model.

Display and durability

Both watches now claim the same peak display brightness: up to 3,000 nits. The Pixel Watch 4's Actua 360 display is a 320 ppi AMOLED LTPO panel with DCI-P3 color, a 1-nit minimum brightness for always-on mode, and a responsive 1–60Hz refresh rate, protected by custom 3D Corning Gorilla Glass 5. Samsung doesn't break out the Galaxy Watch 8's panel type or resolution on its main spec page, but confirms the same 3,000-nit peak brightness figure in its own key-specs comparison table.

Durability is close to identical on paper: the Pixel Watch 4 is rated 5ATM plus IP68, while the Galaxy Watch 8's product page lists 5ATM plus IP68 and also a MIL-STD-810H military durability rating that Google doesn't list for the Pixel Watch 4.

Performance and software

According to Google's tech specs page, the Pixel Watch 4 runs on a Qualcomm Snapdragon W5 Gen 2 chip paired with a Cortex-M55 co-processor, 2GB of RAM and 32GB of eMMC storage, all running Wear OS 6.0. Samsung's own key-specs table lists the Galaxy Watch 8's processor simply as a "3nm, 5-core" chip, also paired with 2GB of RAM and 32GB of storage. Both watches are built on Google's Wear OS platform underneath — Samsung layers its One UI Watch software on top, while the Pixel Watch 4 runs Google's interface closer to stock.

Compatibility is a near match, too: Google requires "most phones running Android 11.0 or newer" for the Pixel Watch 4, while Samsung says the Galaxy Watch 8 "must be paired with a smartphone with Android 11.0 or above and minimum 1.5 gigabyte memory." Samsung's page is explicit that the Galaxy Watch 8 "works seamlessly with Samsung phones and also works with other Android phones" via the Galaxy Wearable and Samsung Health apps — it is not locked to Galaxy devices. Neither watch supports iPhone.

Battery life and charging speed

Battery capacity scales with case size on both watches, but the two companies measure differently. The Pixel Watch 4 packs a 325mAh battery in the 41mm case (rated up to 30 hours with always-on display, or 48 hours in Battery Saver mode) and a 455mAh battery in the 45mm case (up to 40 hours AOD, or 72 hours in Battery Saver mode). Charging the 41mm model reaches 50% in about 15 minutes and 100% in about 45 minutes on the Quick Charge Dock; the 45mm model takes about 60 minutes to fully charge.

Samsung's Galaxy Watch 8 configurator confirms a 325mAh battery in the 40mm case and a 435mAh battery in the 44mm case — but Samsung rates both sizes at the same "up to 30 hours" with always-on display enabled, rather than scaling the claim up for the larger battery the way Google does. In practical terms, that means the smaller 41mm Pixel Watch 4 and either size of Galaxy Watch 8 all claim similar all-day-plus battery life, while only the larger 45mm Pixel Watch 4 claims a meaningfully longer runtime.

Health and fitness tracking

The Pixel Watch 4's sensor array includes a multi-path optical heart rate sensor, red and infrared SpO2 sensors, an ECG-compatible electrical sensor, a skin conductance (cEDA) sensor for body-response tracking, a far-field skin temperature sensor, barometer, magnetometer, compass and altimeter, alongside dual-frequency GPS covering GPS, Galileo and Glonass.

Samsung's Galaxy Watch 8 highlights its own health upgrades for this generation, including an Energy Score, Sleep Apnea detection, Bedtime Guidance, a High Stress Alert, a Running Coach with personalized training plans, personalized heart rate zones, and a new Vascular Load metric that tracks heart-related stress trends overnight. The Galaxy Watch 8 also ships with L1+L5 dual-frequency GPS, matching the Pixel Watch 4's satellite coverage approach.

Both companies gate some of their deepest health insights behind a subscription. Google's Pixel Watch 4 page notes that some of its newest AI-driven health features require a Google Health Premium membership, while Samsung's Bedtime Guidance feature requires the Samsung Health app (version 6.30.2 or later) and a Samsung account login. Neither watch's core heart-rate, SpO2 or sleep-stage tracking is locked behind a paywall — it's the newer, more predictive features on both sides that ask for an account or subscription.

Safety features: where the Pixel Watch 4 pulls ahead

This is the clearest feature gap between the two. The Pixel Watch 4 adds Loss of Pulse Detection, which Google's Pixel Watch 4 page says can detect a loss-of-pulse event and automatically call emergency services, plus satellite SOS that connects to help "through a series of geostationary satellites" even off the grid without a paired phone nearby. Samsung's spec sheet lists SOS and fall detection for the Galaxy Watch 8, but Samsung's own product page does not advertise an equivalent pulse-loss or satellite-SOS capability for this model.

Gemini on your wrist, either way

Google's Gemini assistant isn't exclusive to the Pixel Watch 4 anymore. Samsung's own Galaxy Watch 8 product page highlights Gemini running directly on the watch, citing a reviewer's comment that it "handles long, stream-of-consciousness questions" well. That mirrors the same Gemini-everywhere push Google has been making across Android, and it means the AI assistant on your wrist is now largely the same experience whichever watch you choose, with Google's own Pixel software and Samsung's One UI Watch layer as the main point of difference.

Pixel Watch 4 vs Galaxy Watch 8: full spec comparison

Bottom line: which should you buy

If price is the deciding factor, the Galaxy Watch 8 wins outright: it's $50 cheaper at the entry tier and stays cheaper at every matching size and connectivity option, while still offering a bright 3,000-nit display, dual-frequency GPS and a genuinely useful new health metric in Vascular Load. It's also the easier recommendation if you're the kind of buyer who prefers measured, incremental upgrades over paying extra for the newest safety tech.

The Pixel Watch 4 earns its higher price with two features Samsung doesn't match on the Galaxy Watch 8: Loss of Pulse Detection and satellite SOS, both aimed squarely at buyers who hike, run or exercise alone. The larger 45mm Pixel Watch 4 also claims meaningfully longer battery life than either Galaxy Watch 8 size. Anyone already deep in Google's ecosystem, or who wants to think seriously about long-term battery health before buying a wearable, will find the Pixel Watch 4's longer-runtime 45mm model the more future-proof pick, even at the higher price.

Both watches require an Android phone, both now run Gemini, and neither will work with an iPhone, so the real decision tree is simple: buy the Galaxy Watch 8 to save money without giving up a bright display or solid GPS, or buy the Pixel Watch 4 if Loss of Pulse Detection, satellite SOS or longer battery life in the 45mm size are worth the premium.
