Coros Pace 4 Confirmed for November 10 With AMOLED and ECG

Coros just locked in a November 10, 2025 release date for the Pace 4, and the rumored spec sheet is punching well above the Pace series price point. AMOLED display and ECG monitoring, previously reserved for the Vertix 2S, are both expected to make the cut.

The AMOLED move is a direct response to pressure from Garmin's Forerunner 165 and Apple Watch SE, both of which already run bright, color-rich screens. If Coros keeps the Pace 4 under 40g, an AMOLED panel without killing battery life would be a serious engineering win.

ECG integration is the bigger story. Right now you need a Vertix 2S or a Polar H10 chest strap pairing to get reliable cardiac rhythm data from a Coros ecosystem. Dropping that feature into a lightweight daily trainer watch puts real cardiac screening in more athletes' hands, closer to what Whoop 4.0 and Apple Watch Series 10 offer on the health monitoring side.

The Pace line has always been the entry point for runners who want Coros GPS accuracy and 20-plus hour battery without paying Fenix money. Pace 3 landed at $229. If Pace 4 holds near that range with these upgrades, it reshuffles the budget-to-mid-range running watch category hard.

Verdict: November 10 is close. If the AMOLED and ECG rumors hold, the Pace 4 could be the most compelling running watch under $300 this year.
