Why buy each?

Garmin CIRQA

Garmin metrics, no screen, no subscription

Body Battery, sleep coach, training readiness and VO2 max — the metrics Garmin watch owners rely on — in a screen-free band with no mandatory membership.

Wrist or upper-arm wear

Swap between a wrist band and an upper-arm band, which many users find more comfortable during sleep and more accurate during workouts.

Up to 10-day battery

Up to 10 days between charges, longer than the Fitbit Air's 7 days. A full charge takes up to 90 minutes on Garmin's proprietary charger.

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.
