The 1.5" AMOLED is 50% brighter than the Balance 2 at 3,000 nits, under scratch-resistant sapphire glass — with 21 days of typical use and 41 hours of Accuracy-Mode GPS.
An upgraded processor renders maps 2.5× faster, with dual-frequency L1+L5 GPS across six satellite systems, 64GB of storage, and turn-by-turn offline topo navigation.
A new dual-mode LED flashlight with white, red, and SOS modes joins official HYROX training, golf course maps, and more than 180 sport modes.
