The 46mm Apex 4 delivers 65 hours of GPS tracking and 24 days typical use — enough for multi-day mountain events without charging. The 42mm offers 41h GPS and 15 days.
Global topographic maps with instant rendering, turn-by-turn navigation, POIs, and an underwater depth gauge — the Apex 4 is the first COROS mid-tier with a depth sensor.
Audio alerts, hands-free calling, and voice pin recording — a first for the Apex line, adding practical trail and daily-wear convenience to this mountain sports watch.
Rare for a smartwatch with real GPS and health sensors to work fully on both platforms — Versa 4 does.
Turn-by-turn navigation and NFC payments without needing your phone in hand.
Sleep stages, daily readiness score, Active Zone Minutes, and SpO2 — all on a 6-day charge.
The right pick depends on what you optimize for.
$387 vs $429 over 3 years · no required subscription.

5 sensors.
38g · no required subscription.
Trail runners, ultramarathon athletes, and multisport competitors who want full offline maps and long GPS battery without paying Vertix 2S prices. The speaker and depth gauge make the Apex 4 more capable than any previous Apex for mixed adventure and triathlon use.
