Instinct® 3 – 50 mm, AMOLED — Frequently Asked Questions
Will the Garmin Instinct® 3 – 50 mm, AMOLED fit my wrist?
The Garmin Instinct® 3 – 50 mm, AMOLED looks balanced on flat wrist widths of roughly 53–71mm (about 14.2–19.0cm circumference). Drag the slider above to check it against your own measurement.
What size band does the Garmin Instinct® 3 – 50 mm, AMOLED take?
26mm. Any 26mm 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 Instinct® 3 – 50 mm, AMOLED battery last?
Garmin rates it at 24 days per charge in everyday use.
Is the Garmin Instinct® 3 – 50 mm, AMOLED thick for a 50mm watch?
At 14.4mm, 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 45mm or 50mm Instinct 3?
The Instinct 3 comes in 2 case sizes — 45mm, 50mm. 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 Instinct® 3 – 50 mm, AMOLED?
Rogbid Tank G1, Noise NoiseFit Force, Gionee StylFit GSW7, Zeblaze Thor 5 Pro all sit within half a millimetre of the Garmin Instinct® 3 – 50 mm, AMOLED's 50mm case, so they cover the same amount of wrist.
