Why buy each?

Garmin vivosmart 5

Garmin Body Battery in a band

Body Battery energy monitoring — the feature Garmin is known for — in a wristband that's thinner than most fitness trackers.

HRV status and stress tracking

Continuous heart rate variability monitoring and all-day stress tracking give a more complete picture of recovery and readiness than step counts alone.

Works with Garmin Connect ecosystem

All data syncs to Garmin Connect, compatible with thousands of third-party apps, coaches, and integrations across the Garmin platform.

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.
