The Approach® S44 in short

The figures that decide whether this watch suits you, pulled out of the full specification sheet further down.

  • Between 15 hours and 10 days per charge depending on the power mode — smartwatch at best, gps at worst.
  • Water rated to 5 ATM.
  • 11.4mm thick. Thinner than 87% of 43mm watches, so it slides under a cuff more easily than most of its size.
  • 1.2" (30.4 mm) diameter AMOLED (optional always-on mode) display.
  • Corning® Gorilla® Glass 3 case, Corning® Gorilla® Glass 3 glass.

Does the Approach S44 fit your wrist?

Drag the slider to your wrist width and see the Approach S44 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.

Balanced Fit

43mm on a 55mm wrist

10:09TUE 12lug to lug 43.0mmyour wrist 55.0mm

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 43mm, so you could go bigger.

How to Measure

Measure where you wear it, just below the wrist bone. Either of these works — the tool converts between them.

  1. 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. 2. Around — a tape, or a strip of paper marked and held against a ruler, snug the whole way round.

Against one you know

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.

Approach® S44 — Frequently Asked Questions

Will the Garmin Approach S44 fit my wrist?

The Garmin Approach S44 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 Approach S44 battery last?

Between 15 hours and 10 days per charge, depending on the power mode. Garmin rates Smartwatch at 10 days and GPS at 15 hours; the chart above lists all 2 modes.

How does the Garmin Approach S44 battery compare with other Garmin watches?

At 10 days in everyday use it ranks #211 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 Approach S44 thick for a 43mm watch?

At 11.4mm, thinner than 87% 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 Approach S44?

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 Approach S44's 43mm case, so they cover the same amount of wrist.
