fēnix® 8 – 47 mm, AMOLED — Frequently Asked Questions

Will the Garmin fēnix® 8 – 47 mm, AMOLED fit my wrist?

The Garmin fēnix® 8 – 47 mm, AMOLED looks balanced on flat wrist widths of roughly 49–67mm (about 13.1–17.9cm circumference). Drag the slider above to check it against your own measurement.

What size band does the Garmin fēnix® 8 – 47 mm, AMOLED take?

22mm. Any 22mm strap fits, so you are not limited to Garmin's own bands — look for a quick-release fitting if you want to swap without tools.

How long does the Garmin fēnix® 8 – 47 mm, AMOLED battery last?

Between 10 hours and 23 days per charge, depending on the power mode. Garmin rates Battery Saver at 23 days and All Satellite Systems + Music at 10 hours; the chart above lists all 8 modes.

How does the Garmin fēnix® 8 – 47 mm, AMOLED battery compare with other Garmin watches?

At 16 days in everyday use it ranks #90 of the 257 Garmin watches in our database — the top 35% of the range. The full ranking, including GPS and power-saving figures, is on our Garmin battery life comparison.

Is the Garmin fēnix® 8 – 47 mm, AMOLED thick for a 47mm watch?

At 13.8mm, middle of the pack for thickness at this width. Thickness, not case width, is what decides whether a watch catches on a shirt cuff.

Should I get the 43mm, 47mm or 51mm fēnix 8?

The fēnix 8 comes in 3 case sizes — 43mm, 47mm, 51mm. Which one suits you depends on the flat width of your wrist rather than preference: the larger sizes need a wider wrist to sit inside the edge. Set your measurement in the size picker above and each variant reports its clearance in millimetres.

What other watches are the same size as the Garmin fēnix® 8 – 47 mm, AMOLED?

Oppo Watch X3, Xiaomi Watch 5, CMF Watch 3 Pro, Amazfit Balance 2 all sit within half a millimetre of the Garmin fēnix® 8 – 47 mm, AMOLED's 47mm case, so they cover the same amount of wrist.
