Our take on each
Google Pixel Watch 4 (45mm, Wi-Fi)
Best for: Android owners, especially Pixel owners, who run or hike and want the longest battery of these three.
The Pixel Watch 4 is the Android watch that answers the Apple Watch on its own terms, and in battery it beats it. Google rates the 45mm model at up to 40 hours with the always-on display running, against Apple's 24 hours, and the new side charging dock adds roughly 15 hours of use in about 15 minutes. That is two nights of sleep tracking between charges for most owners.
The hardware is the most ambitious of the three. The Actua 360 domed display is 10 percent larger and up to 3,000 nits bright, under scratch-resistant Gorilla Glass. Dual-frequency GPS gives tighter route tracking on runs and hikes among tall buildings or trees, and Fitbit's running and sleep tools are built in, with 40-plus exercise modes. Gemini handles voice requests and drafts quick replies. It carries IP68 and 5ATM ratings.
The costs: it needs an Android phone, and some features work best with a Pixel. Some coaching features sit behind a paid Google subscription. At 45mm the case is large on small wrists, and $399.99 at our Oct 1 check is the top of this ladder, $100 above the Galaxy Watch 8.
Samsung Galaxy Watch 7 (40mm, Bluetooth)
Best for: Samsung Galaxy phone owners who want a full Wear OS smartwatch without paying flagship money.
The Galaxy Watch 7 is the cheapest real smartwatch in our catalog, meaning a full app store, Google Wallet, Gemini voice help and third-party watch faces rather than the fixed menus of a fitness band. Samsung built it on the 3 nm Exynos W1000 with 2 GB of RAM and 32 GB of storage, the same chip that went into the Galaxy Watch Ultra, so menus and apps stay quick.
The 40mm model has a 1.3-inch Super AMOLED screen at 432 x 432 and weighs 28.8 g, which suits smaller wrists and overnight wear. It carries IP68 and a 5ATM water rating, so laps in a pool are fine.
Two limits shape who should buy it. First, the 300 mAh battery is small: Samsung quotes up to 40 hours with the always-on display off, and owners commonly report needing a charge every day with it on. Second, the best features are tied to Samsung phones. Galaxy AI insights and sleep apnea detection need a Galaxy phone with Samsung Health, so on a Pixel or another Android phone you get a plainer watch.
Price moves often. We saw $159 on Oct 12 and $234.99 a week later.
