Google Pixel Watch 3 vs OnePlus Watch 2
Side-by-side specifications, scores and verdict.
Quick Verdict
Pixel Watch 3 delivers superior display technology with its 2000-nit LTPO AMOLED Actua screen and Wear OS 5, offering faster performance and more comprehensive health tracking including ECG and skin temperature monitoring. OnePlus Watch 2 counters with exceptional battery longevity—100 hours in smart mode versus 24 hours—plus a brighter 466x466 AMOLED display and premium stainless steel construction at a $50 discount. Health tracking favors Google with ECG capabilities, while fitness enthusiasts valuing multi-week battery life may prefer OnePlus. Display quality, software freshness, and health features give Pixel Watch 3 the edge for most users, though OnePlus appeals to those prioritizing battery endurance and ruggedness over cutting-edge features.
