Pacer Pro
Polar Pacer Pro is a watch from 2022, sitting in the mid-range band at an indicative $349.
It reads 15 of the 33 signals this comparison tracks. Nothing at all from body composition. Rarer readings it does take: sleep efficiency.
By sensor class: 5 at high accuracy and 4 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 7 days per charge are the 64th longest of the 74 devices of its kind here that publish a figure. The transflective MIP screen can stay always on. Built-in GPS. Rated WR50 / 50m, fine for swimming. It weighs 41 g. Case size 45mm. No subscription is required.
Lightweight runner; MIP, barometer, wrist running power; no SpO2/skin-temp/ECG.

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.
