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.

Suunto Vertical

AMOLED display — first for the Vertical line

The Vertical 2 replaces the MIP screen with a bright 1.5" AMOLED LTPO — delivering vivid colour maps and improved night readability while still providing 65 hours of dual-band GPS.

Built-in LED flashlight

An integrated LED flashlight is new to the Vertical 2, adding practical trail and camp utility without a separate device — especially useful for early morning and night runs.

Full offline maps, 65h GPS, AI Coach

Global topographic maps with dual-band GPS, 20-day smartwatch battery, and an AI Coach that personalises training load and recovery recommendations directly on the watch.
