Why buy each?

Garmin Forerunner 165

AMOLED display at entry-level price

The FR165 is the first Garmin entry-level running watch with an AMOLED display — dramatically more readable than the LCD it replaces.

Full Garmin running analytics

Training load, recovery time, Body Battery, HRV status, VO2 max estimation — the same analytics found on watches costing twice as much.

11 days of battery

11 days typical use and roughly 19 hours GPS — enough for most training blocks without mid-week charging.

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.

Multi-band GPS, 12-day battery

SatIQ multi-band GPS for precise tracking in cities and trails, with up to 12 days of battery life in the 45mm model — significantly more than any comparable smartwatch.
