21 days typical use and 33 hours GPS — combined with a scratch-resistant sapphire glass 1.5" AMOLED that outshines most watches at this price.
Precise dual-frequency L1+L5 GPS across six satellite systems, with downloadable offline topo maps and turn-by-turn navigation — rare at this price tier.
First Amazfit with official HYROX training and competition modes, 40,000-course golf maps, and SCUBA dive support — more sport breadth than any previous Balance.
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.
