Why buy each?

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.

Garmin Venu

Garmin Body Battery

Garmin's signature energy monitoring tracks stress, sleep, and heart rate variability to give you a daily 0–100 energy score — more nuanced than raw step counts.

Nap detection

The Venu 3 automatically detects when you nap during the day and logs it accurately in your sleep data — a unique wellness feature among smartwatches.

AMOLED display, 14-day battery

Most AMOLED smartwatches last 1–2 days. Garmin's efficient software architecture stretches the Venu 3 to 14 days — a huge practical advantage.
