Garmin Approach J1 vs Approach S70 47mm
Size, specs & wrist fit compared

Which one fits you
On wrists narrower than about 49mm, the Approach J1 is the safer pick — it stays proportionate down to roughly 45mm, where the Approach S70 47mm starts to hang over the edge. Above 49mm both sit cleanly, and the Approach S70 47mm gives you more presence.
The Approach S70 47mm wears larger than the Approach J1 (47mm vs 43mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Approach J1 is the slimmer of the two (11.4mm vs 13.4mm), so it slides under a cuff more easily.
On the wrist the Approach J1 feels lighter (29g vs 56g, case only).
Among the 318 43mm watches we hold thickness for, the Approach J1 is thinner than 87%, so it wears flatter than its width suggests.
The Approach S70 47mm is middle-of-the-pack for thickness among the 102 47mm watches in the database.
The Approach S70 47mm is 4mm wider, 4mm longer, 2mm thicker and 27g heavier than the Approach J1. Both are circular.

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
43mm 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 43mm, 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.

- Across the wrist6.0mm spare each side

Light enough to forget you have it on. (0.5g per mm of wrist)

Sweet Spot
47mm on a 55mm wrist
Across the wrist it works — 4.0mm spare each side — but wide enough that the edge of the case back lifts clear of the skin.
