- fiber-reinforced polymer with polymer rear cover case, Corning® Gorilla® Glass 3 glass.
Does the First Avenger fit your wrist?
Drag the slider to your wrist width and see the First Avenger overlaid at true scale. Lug-to-lug — not case diameter — decides whether a watch overhangs your wrist.
Watch Fit Tool
For sports watches, lug-to-lug (L2L) is what matters most — it decides whether a watch overhangs your wrist. Bulky is fine; overhang is not.
Measure at the point where you wear your watch — typically just below the wrist bone.
Flat width — lay your arm on a table, palm facing up, and measure straight across the top of your wrist with a ruler. Bone to bone; do not follow the curve down the sides.
Around — wrap a tape measure snugly round the wrist. No tape? Wrap a strip of paper, mark the overlap and hold the strip against a ruler.
Width ≠ circumference. They are different numbers — around 170mm is about 64mm across — so set the toggle to whichever one you actually measured before you type it in.

Balanced Fit
45.1mm on a 55mm wrist
Comfortably inside the edges of your wrist, and it seats and sits low enough to wear without thinking about it.
On a 55mm wrist the sweet spot is 47–53mm lug to lug. This one is 45.1mm, so you could go bigger.
Measure where you wear it, just below the wrist bone. Either of these works — the tool converts between them.
- 1. Flat width — arm flat on a table, palm up. Measure straight across the top of the wrist, bone to bone, ignoring the curve down the sides.
- 2. Around — a tape, or a strip of paper marked and held against a ruler, snug the whole way round.
Leather: Attaches at the lugs, so the case back rests on your skin. Thins and softens with wear. Typical figures, not this model’s own.

First Avenger — Frequently Asked Questions
Will the Garmin First Avenger fit my wrist?
The Garmin First Avenger looks balanced on flat wrist widths of roughly 47–64mm (about 12.6–17.1cm circumference). Drag the slider above to check it against your own measurement.
How long does the Garmin First Avenger battery last?
Between 6 hours and 8 days per charge, depending on the power mode. Garmin rates Smartwatch at 8 days and GPS with music at 6 hours; the chart above lists all 3 modes.
How does the Garmin First Avenger battery compare with other Garmin watches?
At 8 days in everyday use it ranks #235 of the 285 Garmin watches in our database — below the middle of the range. The full ranking, including GPS and power-saving figures, is on our Garmin battery life comparison.
Is the Garmin First Avenger thick for a 45mm watch?
At 12.8mm, thinner than 68% of 45mm 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 First Avenger?
OnePlus Watch Lite, Oppo Watch S, Google Pixel Watch 4 - 45mm, Tissot T-Race Chronograph PVD / Black / Rubber all sit within half a millimetre of the Garmin First Avenger's 45.1mm case, so they cover the same amount of wrist.
