Forerunner 70

Garmin Forerunner 70 is a watch from 2026, sitting in the budget band at an indicative $249.

It reads 16 of the 33 signals this comparison tracks. 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 a spot reading you take yourself, not a continuous one.

Its 13 days per charge are the 48th longest of the 76 devices of its kind here that publish a figure. The AMOLED screen can stay always on. Built-in GPS. Rated 5ATM / 50m, fine for swimming. It weighs 40 g. Case size 43mm. No subscription is required.

Entry-level runner from May 2026, above the Forerunner 55 it replaces. Adds Training Readiness over the Forerunner 165 but has no barometer, so no floors climbed.
