Why buy each?

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).

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.
