Forerunner 70 — Frequently Asked Questions
Will the Garmin Forerunner 70 fit my wrist?
The Garmin Forerunner 70 looks balanced on flat wrist widths of roughly 45–61mm (about 12.0–16.3cm circumference). Drag the slider above to check it against your own measurement.
How long does the Garmin Forerunner 70 battery last?
Garmin rates it at 13 days per charge in everyday use.
Is the Garmin Forerunner 70 thick for a 43mm watch?
At 11.9mm, thinner than 83% of 43mm watches, so it slides under a cuff more easily than most of its size. Thickness, not case width, is what decides whether a watch catches on a shirt cuff.
What other watches are the same size as the Garmin Forerunner 70?
OnePlus Watch 3 43mm, Oppo Watch X2 Mini, Omega Speedmaster Moonphase Stainless Steel / Black Meteorite / Bracelet, Zenith Defy Extreme Diver Shadow / Bracelet all sit within half a millimetre of the Garmin Forerunner 70's 42.6mm case, so they cover the same amount of wrist.
