First Fenix to include a speaker — enabling phone calls, Bluetooth audio, and voice prompts directly from the watch.
AMOLED for the best display at 18 days. Solar MIP for up to 48+ days in expedition conditions where charging is impossible.
EN13319 dive mode (up to 40m), MIL-STD-810 shock resistance, and TopoActive maps covering 100+ countries — the most capable outdoor watch in Garmin's lineup.
Five times the battery of the Vantage V3 — enough for week-long mountain stages or ultramarathons without charging access.
Automatically segments your run by uphill and downhill sections, calculating pace and power for each — essential for mountain race training.
Running power without a chest strap or foot pod — Polar's key differentiator versus Garmin at this price tier.
The right pick depends on what you optimize for.
