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 Forerunner 170

Training Readiness at entry level

Training Readiness, full Training Status, and wrist-based running power — analytics previously reserved for Garmin's mid-range — now on a $299.99 watch.

AMOLED display and 10-day battery

A bright 1.2" AMOLED touchscreen with a traditional 5-button design, up to 10 days of battery in smartwatch mode and around 17 hours of GPS.

Garmin Pay and 80+ sports apps

Contactless payments arrive on the entry Forerunner for the first time, alongside 80+ built-in sports apps and Garmin Coach adaptive training plans.
