COROS PACE 4 Pro
COROS PACE 4 Pro is a watch from 2026, sitting in the premium band at an indicative $449.
It reads 15 of the 33 signals this comparison tracks. Full coverage of activity. Nothing at all from body composition.
By sensor class: 6 at high accuracy and 2 at consumer grade. That grade is my classification of the hardware, not a lab test. Those readings come from an optical heart rate sensor, ECG electrodes, an optical blood oxygen sensor, a GPS receiver, a barometer and an accelerometer. Blood oxygen is a spot reading you take yourself, not a continuous one.
Its 21 days per charge are the 22nd longest of the 80 devices of its kind here that publish a figure. The AMOLED screen can stay always on. Multi-band GPS. Rated 5ATM, fine for swimming. On top of the tracking it also handles music on the device and offline maps. No subscription is required.
September 2026 step up from the PACE 4: a titanium bezel, a bigger sapphire AMOLED screen, offline maps, a speaker, SpO2 and the ECG sensor COROS also fits to the PACE Pro.

Not established: ECG recording, AFib detection. The maker does not state it and no independent test I trust settles it. The signal counts on this page only include confirmed signals, so it is left out of them, which is not the same as the device lacking it.

Turn a supported wearable into daily health scores
MyBodyAI reads COROS, Oura, Polar and Withings by logging in, Fitbit and Pixel Watch through Google Health, and Garmin through the Android app or a data export, then builds daily recovery, sleep, load and immune scores, a biological age estimate, and early warnings. Optional, and separate from this comparison.
This comparison is free and ad-free. One developer builds and updates it. If it saved you hours of research, a coffee is a kind way to say thanks.
