Garmin Venu

ECG and Garmin Body Battery

The Venu 4 adds on-demand ECG (a first for the Venu line) alongside Garmin's signature Body Battery energy score — combining health monitoring and daily readiness in one watch.

Built-in flashlight and speaker

A white/red LED flashlight and a speaker/microphone for hands-free calling — practical features that set the Venu 4 apart from the Venu 3.
