Size, specs & wrist fit compared

Which one fits you
Both need much the same wrist — roughly 44–61mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.
The Approach S44 wears larger than the Approach S70 42mm (43mm vs 42mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Approach S44 is the slimmer of the two (11.4mm vs 12.6mm), so it slides under a cuff more easily.
On the wrist the Approach S44 feels lighter (42g vs 44g, case only).
Among the 318 43mm watches we hold thickness for, the Approach S44 is thinner than 87%, so it wears flatter than its width suggests.
The Approach S70 42mm is middle-of-the-pack for thickness among the 655 42mm watches in the database.
The Approach S44 is 1mm wider, 1mm longer, 1.2mm thinner and 2g lighter than the Approach S70 42mm. 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.

Case 43.0mm · Lug-to-lug 43.0mm · Thickness 11.4mm · 42g
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.
