Forerunner 165

Garmin Forerunner 165 is a watch from 2024, sitting in the budget band at an indicative $249.

It reads 16 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: 10 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 measured during sleep, not continuously through the day.

Its 11 days per charge are the 53rd longest of the 74 devices of its kind here that publish a figure. The AMOLED screen can stay always on. Built-in GPS. Rated 5ATM / WR50, fine for swimming. It weighs 39 g. On top of the tracking it also handles contactless payments. Case size 43mm. No subscription is required.

Entry AMOLED running watch; Gen 4. VO2max + race predictor but no Training Status/Load/Readiness.
