Garmin Vivoactive 5 vs Google Pixel Watch 3
The Verdict
Garmin Vivoactive 5 and Google Pixel Watch 3 target different smartwatch priorities. Garmin's strength lies in battery endurance, delivering 11 days of smartwatch use versus Google's 24 hours with always-on display enabled, or 36 hours in Battery Saver mode. Garmin's AMOLED display reaches 390x390 resolution on its 1.2-inch screen, matching Google's 408x408 resolution on an identically-sized display, though Google's Actua technology delivers superior brightness at 2000 nits. Health tracking heavily favors Google Pixel Watch 3, which includes ECG and skin temperature monitoring absent on Vivoactive 5. Both track heart rate, SpO2, and sleep. Google runs Wear OS 5 with fuller app ecosystem support, while Garmin uses proprietary Garmin OS with Connect IQ apps, limiting third-party compatibility. Google's Pixel Watch 3 weighs 31 grams compared to Garmin's 36 grams. Both offer 5ATM water resistance, though Google adds IP68 dust protection. At $299, Garmin targets fitness-focused users who prioritize battery longevity and simpler interfaces. Google's $349.99 Pixel Watch 3 suits those wanting comprehensive health monitoring and deeper smartphone integration. Choose Garmin if you need 11-day battery life and prefer Garmin's fitness ecosystem. Pick Pixel Watch 3 if advanced health sensors and Wear OS apps matter more than battery endurance.
