The Descent™ G1 in short
The figures that decide whether this watch suits you, pulled out of the full specification sheet further down.
- Between 25 hours and 48 days per charge depending on the power mode — battery saver at best, dive at worst.
- Water rated to Dive (100 meters).
- 61g on the wrist. Heavier than 82% of the 46mm watches we have weights for.
- custom, two-window design: 0.9” x 0.9” (23 x 23 mm) Monochrome, sunlight-visible, transflective memory-in-pixel (MIP) display.
- Takes 22mm bands, so third-party straps fit without an adapter.
Does the Descent G1 fit your wrist?
Drag the slider to your wrist width and see the Descent G1 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.

Case 45.5mm · Lug-to-lug 45.5mm · Thickness 15.2mm · 61g
Balanced Fit
45.5mm on a 55mm wrist
Across the wrist it works — 4.8mm 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 45.5mm, 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.

Which Descent G1 size fits you?
This model comes in 2 versions. Set your measurement and each one reports its own verdict — tap any size to open its page.
Which of these fits your wrist?
Roughly a 14.7cm wrist circumference — the measurement a tape gives you. Compared against lug-to-lug where we have it, case width otherwise.
All 2 Descent G1 variants fit this wrist. The 45.5mm gives you the most presence without overhanging; the smallest is the discreet end of the range.

Descent™ G1 — Frequently Asked Questions
Will the Garmin Descent G1 fit my wrist?
The Garmin Descent G1 looks balanced on flat wrist widths of roughly 48–65mm (about 12.8–17.4cm circumference). Drag the slider above to check it against your own measurement.
What size band does the Garmin Descent G1 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 Descent G1 battery last?
Between 25 hours and 48 days per charge, depending on the power mode. Garmin rates Battery Saver at 48 days and Dive at 25 hours; the chart above lists all 6 modes.
How does the Garmin Descent G1 battery compare with other Garmin watches?
At 48 days in everyday use it ranks #51 of the 285 Garmin watches in our database — the top 18% of the range. The full ranking, including GPS and power-saving figures, is on our Garmin battery life comparison.
Is the Garmin Descent G1 thick for a 46mm watch?
At 15.2mm, thicker than 82% of 46mm 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 Descent G1?
Honor Watch 5 Pro - Bluetooth, Huawei Watch GT 6 - 46mm, Samsung Galaxy Watch8 LTE Classic, Omega Seamaster Planet Ocean 600M Co-Axial Worldtimer 45.5 Master Chronometer GMT Ceramic / Black - Grey / Rubber all sit within half a millimetre of the Garmin Descent G1's 45.5mm case, so they cover the same amount of wrist.
