COROS Vertix 4 is on the way. We recommend waiting unless you need a watch right now.

Leaked September 2026 — no launch date announced
A COROS Vertix 4 appeared in a Eurasian Economic Union regulatory filing in September 2026. COROS appears to be skipping the Vertix 3 name to align with the Pace 4 and Apex 4. COROS has not confirmed the watch, its specifications, or a launch window.
Expedition athletes, mountaineers, and ultra-endurance competitors who do multi-day or multi-week events where charging is impossible. If you need GPS tracking for 140 continuous hours, no other watch comes close.
Key strengths
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.
GPS + GLONASS + Galileo + BeiDou + QZSS with dual-frequency reduces error in challenging terrain to near-meter precision.
Military-grade scratch and impact resistance for the harshest environments: extreme altitude, cold, and sustained physical stress.
The COROS Vertix 2S, released October 2023, is the world's longest-lasting GPS sports watch — delivering 140 days of smartwatch battery and 140 hours of GPS navigation. Designed for expedition athletes, mountaineers, and multi-day racers who cannot charge in the field, it combines 5-satellite dual-frequency GPS, full topographic maps, and COROS's EvoLab training platform.
Yes, for anyone who has regular charging access. The Vertix 2S is designed for true expedition conditions. For most runners and triathletes, the Apex 4 or Pace 4 offers better value.
Vertix 2S delivers longer GPS battery (140h vs up to 75h on the 51mm Fenix 9 Pro Solar, or about 124h with solar charging) and costs at least $400 less. Garmin Fenix 9 Pro has an AMOLED option, optional inReach satellite and LTE connectivity, more sport modes, deeper analytics, and a more established ecosystem. Both are premium expedition watches — choose COROS for raw battery, Garmin for features.
The Vertix 2S is 3 years old, and a Vertix 4 appeared in a regulatory filing in September 2026 — COROS appears to be skipping the Vertix 3 name. Nothing is officially announced. If you need a watch for an expedition now, buy it. Otherwise it is worth waiting for a COROS announcement before committing.
Up to 140 hours with GPS active. In full power GPS mode with all sensors, expect 50–70 hours. In daily smartwatch use: up to 60 days. This is best-in-class battery life for an expedition GPS watch.
Yes — it has offline maps, route navigation, music storage, and can log activities without a phone present. It only needs the phone for syncing data to the COROS app and downloading new maps or routes.
