COROS PACE 4
COROS PACE 4 is a watch from 2025, sitting in the mid-range band at an indicative $249.
It reads 13 of the 33 signals this comparison tracks. Full coverage of activity. Nothing at all from body composition.
By sensor class: 5 at high accuracy and 3 at consumer grade. That grade is my classification of the hardware, not a lab test. Those readings come from an optical heart rate sensor, a GPS receiver, a barometer and an accelerometer.
Its 19 days per charge are the 28th longest of the 74 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. Case size 43.4mm. No subscription is required.
Current lightweight AMOLED running watch (no offline maps); successor to Pace 3; SpO2 not listed.

Turn a supported wearable into daily health scores
MyBodyAI reads Fitbit, Oura, Polar and Withings by logging in, and Garmin from 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. I build and update it on my own. If it saved you hours of research, a coffee genuinely makes my day.
