Forerunner 965

Garmin Forerunner 965 is a watch from 2023, sitting in the premium band at an indicative $599.

It reads 18 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 23 days per charge are the 19th 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 / WR50, fine for swimming. It weighs 53 g. On top of the tracking it also handles music on the device, contactless payments and offline maps. Case size 47mm. No subscription is required.

AMOLED running/tri flagship; Elevate Gen 4 (no ECG). Full training suite incl Training Readiness.
