Forerunner 570 (47mm)
Garmin Forerunner 570 (47mm) is a watch from 2025, sitting in the premium band at an indicative $549.
It reads 19 of the 33 signals this comparison tracks. Full coverage of activity. Nothing at all from body composition. Rarer readings it does take: Body Battery.
By sensor class: 11 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, 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 11 days per charge are the 55th longest of the 76 devices of its kind here that publish a figure. The AMOLED screen can stay always on. Multi-band GPS. Rated 5ATM / 50m, fine for swimming. It weighs 50 g. On top of the tracking it also handles music on the device and contactless payments. Case size 42mm & 47mm. No subscription is required.
May 2025 successor to the Forerunner 265. Carries the newer optical sensor and skin temperature, but Garmin did not enable the ECG app on it.

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.
