Why buy each?

Garmin Fenix

Built-in speaker and microphone

First Fenix to include a speaker — enabling phone calls, Bluetooth audio, and voice prompts directly from the watch.

AMOLED or Solar: choose your battery priority

AMOLED for the best display at 18 days. Solar MIP for up to 48+ days in expedition conditions where charging is impossible.

Certified for diving, rated for mountains

EN13319 dive mode (up to 40m), MIL-STD-810 shock resistance, and TopoActive maps covering 100+ countries — the most capable outdoor watch in Garmin's lineup.

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.
