Why buy each?

Amazfit Band 7

18-day battery at under $50

18 days of typical use with health monitoring — nearly 3 weeks without charging, far beyond any smartwatch competitor.

Alexa built-in

Ask Alexa for weather, timers, reminders, and smart home controls directly from your wrist — unusual for a sub-$50 fitness band.

PAI health scoring

Amazfit's Personal Activity Intelligence score aggregates your daily activity into a single 0–100 health index, guiding you toward optimal activity levels.

Apple Watch Ultra

50-hour battery + satellite SOS

The Ultra 4 lasts roughly twice as long as the Series 12, with up to 45 hours of GPS workout tracking in Max Extended Workout mode. Satellite Emergency SOS works without cellular or WiFi coverage.

Heart rate every five seconds

The new health sensing system samples heart rate every five seconds all day and HRV every five minutes, feeding a 0–10 readiness score.

3000-nit titanium-cased powerhouse

The 49mm titanium case and 3000-nit display make this watch usable in full direct sunlight and water depths up to 100m (recreational scuba diving to 40m).
