SATISFY COROS APEX 4

From the first watch face check before dawn to the last aid station, the APEX 4 holds through everything. Track a threshold session on the road, log vert on a technical climb, navigate an unfamiliar ridge line by GPX alone.

Sixty-five hours of battery life carries a watch through a full UTMB cutoff without a charge, and the barometer reads the sky before the first step out the door. Built for movement across road, trail, and alpine terrain.
