The fēnix® 5S in short
The figures that decide whether this watch suits you, pulled out of the full specification sheet further down.
- Rated for 35 hours of use per charge.
- 67g on the wrist. Heavier than 88% of the 42mm watches we have weights for.
- 1.1” (27.94 mm) diameter display.
- Takes 20mm bands, so third-party straps fit without an adapter.
Does the Fenix 5S fit your wrist?
Drag the slider to your wrist width and see the Fenix 5S 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
42mm on a 55mm wrist
Across the wrist it works — 6.5mm spare each side — but a tall watch on this wrist. Fine over a sleeve, awkward under one.
On a 55mm wrist the sweet spot is 47–53mm lug to lug. This one is 42mm, 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.

What size band does the Garmin Fenix 5S take?

How long does the Garmin Fenix 5S battery last?

How does the Garmin Fenix 5S battery compare with other Garmin watches?
At 9 days in everyday use it ranks #230 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 Fenix 5S thick for a 42mm watch?
At 15mm, thicker than 86% of 42mm watches — it will sit noticeably high on the wrist. 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 Fenix 5S?
Certina DS Action Chrono PVD / Carbon / Bracelet, Omega Speedmaster Professional Moonwatch 3861 Moonshine Gold / Black Lacquer, TAG Heuer Carrera Chronograph Seafarer Stainless Steel / Silver, Huawei Watch 5 - 42mm all sit within half a millimetre of the Garmin Fenix 5S's 42mm case, so they cover the same amount of wrist.
