The COROS APEX 4 arrives with a reputation long-time mountain athletes already understand: it’s built for people who care far more about accurate data and long battery life than having an AMOLED light show on their wrist. And after a month of using the 46mm version for trail runs, and steady training weeks, it’s clear that COROS hasn’t over promised here.
