Why buy each?

Garmin Venu

ECG and Garmin Body Battery

The Venu 4 adds on-demand ECG (a first for the Venu line) alongside Garmin's signature Body Battery energy score — combining health monitoring and daily readiness in one watch.

Built-in flashlight and speaker

A white/red LED flashlight and a speaker/microphone for hands-free calling — practical features that set the Venu 4 apart from the Venu 3.

Multi-band GPS, 12-day battery

SatIQ multi-band GPS for precise tracking in cities and trails, with up to 12 days of battery life in the 45mm model — significantly more than any comparable smartwatch.

OnePlus Watch

5-day Wear OS battery — finally

The dual-engine Snapdragon W5 + BES2800 co-processor architecture delivers up to 5 days in Smart Mode — 2–3× longer than most Wear OS rivals. A 10-minute charge provides a full day of use.

Dual-frequency GPS on a $329 watch

L1 + L5 dual-band GPS gives running and cycling route accuracy typically found only on $500+ sports watches — accurate to within metres even in urban canyons.

Full Wear OS 5 with Google ecosystem

Google Maps turn-by-turn navigation, Google Wallet contactless payment, and Play Store app access — plus Google Health Connect integration for the full Android wearables ecosystem.
