    Expert Review

    Recently upgraded from my Apex 2 (which I used for 3+ years). Flashy! Better button and dial placement. Some new cool features like maps on a separate set of screens from the other metrics. Still super awesome user interface. (this is why I like coros over some other watch brands)

    Apex 4 by COROS — recommended by Robyn Lesh

    This product is for…

    Trail runners, ultramarathon athletes, and mountain sports enthusiasts who prioritize battery life, navigation, and clean data over smartwatch connectivity. The 42mm size is specifically noted as a good fit for smaller wrists.

    Worth noting…

    The Apex 4 adds a faster processor, sapphire glass, street-name maps with POIs, and button/dial improvements over the Apex 2. It does not reset during mid-activity charging and supports GPX file loading for race course navigation.
