Google Pixel Watch 4 45mm
Wear OS AI smartwatch with Fitbit (Android only) · Reviewed by Drew · amazon.com live, Sept 28 2026
Why it scored a 78
At $379.90 full MSRP, the Google Pixel Watch 4 45mm is a Wear OS smartwatch with a domed 3,000-nit Actua display, dual-frequency GPS, ECG and skin-temperature sensing, and Gemini built in. Reliability leads at 87 and Satisfaction sits at 88, but Value drags at 72 because the price is undiscounted and battery runs about a day and a half. The caveats: it is Android only, the Wi-Fi model cannot use satellite SOS or standalone calls, and Daily Readiness and advanced sleep insights sit behind Fitbit Premium at $9.99 a month after the six-month trial. It is for Android owners who want Gemini and Fitbit tracking in a repairable watch.

Should you buy the Google Pixel Watch 4 45mm?
The Google Pixel Watch 4 45mm is for Android users, ideally Pixel phone owners, who want Gemini on the wrist, Fitbit tracking, and a watch that can finally be repaired. It ranks tenth of ten at $379.90. That is not a knock on the hardware; Reliability scores 87 and Satisfaction 88. It is a knock on price and battery. The Samsung Galaxy Watch 8 40mm does most of the same things for $100 less and scores four points higher.
Where it earns its score

- Loss of Pulse Detection. Alongside ECG, skin temperature, and blood oxygen.
- Dual-frequency GPS. Plus 5 ATM and IP68 ratings.
What to know first
- Value scores 72. $379.90 undiscounted for about a day and a half of battery.
- Fitbit Premium costs extra. $9.99 a month after a six-month trial for the full analytics.
- Android only. And the Wi-Fi model has no satellite SOS or standalone calls.
- Warranty is the lowest factor. One year, scoring 55.
Our verdict
The Pixel Watch 4 45mm scores 78, Fair Buy, and it is a good watch at a price that does not compete. Buy it if you own a Pixel phone and want Gemini and Fitbit. Most Android users should buy the Samsung Galaxy Watch 8 40mm instead: 82 at $299, with blood pressure and no subscription pitch.
