Pixel Watch 3 45mm overview

The Google Pixel Watch 3 is a 45mm Android smartwatch built for fitness tracking and everyday connectivity. It ships new with a matte black aluminum case and an Obsidian Active Band in both small and large sizes. The round AMOLED touch display supports customizable watch faces with adjustable brightness. Onboard storage of 32GB holds apps and music for phone-free use.

Who this suits and who it does not

Runners and swimmers gain advanced metrics from Fitbit integration including pace, laps swam, and automatic workout detection. Health-focused users benefit from continuous heart-rate monitoring, ECG, blood-oxygen readings, skin-temperature tracking, and sleep-stage analysis. Buyers who need cellular connectivity for calls and data without a paired phone should look elsewhere because this model is Wi-Fi only. Those requiring multi-day battery life beyond the rated 24 hours will also need a different device.

Setup checks before ordering

Verify your phone runs a compatible Android version with Wear OS support to enable full feature access. Ensure you can charge the watch via the included USB-C cable and a suitable power source. Confirm your wrist circumference falls within the 150215mm range covered by the supplied small and large sport-loop bands. The watch carries a 5 ATM water-resistance rating up to 164 ft, suitable for swimming but not for high-velocity water sports.
