Why buy each?

Apple Watch SE

Full watchOS at a lower price

Access the entire watchOS app ecosystem, Apple Pay, Siri, and Family Setup — for $150 less than the Series 11.

Crash and fall detection

Emergency SOS, fall detection, and Crash Detection give real safety value even without premium health sensors.

Aluminium in four colours

Available in Midnight, Starlight, Silver, and (PRODUCT)RED with a wide range of Apple Watch-compatible bands.

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.
