Why buy each?

COROS Vertix

140 hours of continuous GPS

No other GPS watch currently on the market delivers 140 hours of GPS tracking — enough for most ultra-endurance events and multi-day mountain traverses.

5-satellite dual-frequency system

GPS + GLONASS + Galileo + BeiDou + QZSS with dual-frequency reduces error in challenging terrain to near-meter precision.

Sapphire glass and titanium case

Military-grade scratch and impact resistance for the harshest environments: extreme altitude, cold, and sustained physical stress.

Garmin Forerunner 265

Multi-band GPS accuracy

L1+L5 multi-band GPS reduces position drift in urban canyons and dense forest.

Training readiness score

Daily score combining HRV status, sleep, acute load, and recovery time.
