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.

Polar Grit X

40-day battery for trail and ultra runners

Five times the battery of the Vantage V3 — enough for week-long mountain stages or ultramarathons without charging access.

Hill splitter auto-detection

Automatically segments your run by uphill and downhill sections, calculating pace and power for each — essential for mountain race training.

Wrist running power at mid-range price

Running power without a chest strap or foot pod — Polar's key differentiator versus Garmin at this price tier.
