Why buy each?

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.

Xiaomi Smart Band 10

Brighter AMOLED at under $40

The Smart Band 10's 1.72" display peaks at 1500 nits — 200 nits brighter than the Band 9 — making it more readable in sunlight, all for around $40.

21-day battery with health monitoring

Continuous heart rate, SpO2, stress, and sleep tracking — all running for 3 weeks before charging. Seven more days than the already impressive Band 9.

Works with iPhone and Android

Full functionality on both platforms via the Mi Fitness app, including notifications, sleep analysis, and health trends. Bluetooth 5.4 for improved connection stability.
