💡About the COROS Apex
The COROS Apex 4, released October 2025, is COROS's mid-tier mountain sports watch — delivering full offline maps, 24-day battery (65h GPS on the 46mm), multi-band GPS, running power, speaker and microphone for audio alerts and hands-free calling, and an underwater depth gauge. Available in 42mm ($429) and 46mm ($479) with Grade 5 titanium and sapphire glass.
- 65h GPS, 24-day battery (46mm)
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.
- Full offline maps and depth gauge
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.
- Speaker, microphone, and voice notes
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.
🎯Who is this for?
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.
❓FAQs
What is new in COROS Apex 4 vs Apex 2 Pro?
Apex 4 adds a built-in speaker and microphone, an underwater depth gauge, faster map rendering, voice notes, and audio lap alerts. Battery life is similar. It comes in 42mm and 46mm (vs single 47mm) and starts at $429.
How does COROS Apex 4 compare to Garmin Forerunner 970?
Apex 4 (46mm) has longer battery (24 days vs 15 days) and 65h GPS vs 26h GPS at a lower price ($479 vs $749). Garmin FR970 adds ECG, a brighter AMOLED display, deeper training analytics, and Triathlon Coach. Choose COROS for battery and price; Garmin for analytics depth and ECG.
Does COROS Apex 4 have full offline maps?
Yes — it comes with global offline topographic maps, instant rendering with POIs and street names, and full turn-by-turn navigation. One of the best map implementations in any sub-$500 sport watch.
Is COROS Apex 4 good for ultramarathons?

Does COROS Apex 4 have ECG?
No — COROS Apex 4 does not have ECG. It has optical heart rate, HRV, SpO2, skin temperature, and training load. For ECG in a multisport watch, look at the Garmin Forerunner 970 or Polar Vantage V3.
