Approach J1 vs Approach® S70 - 42 mm
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 J1 wears larger than the Approach® S70 - 42 mm (43mm vs 42mm 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 12.6mm), so it slides under a cuff more easily.
On the wrist the Approach J1 feels lighter (29g vs 44g, 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 - 42 mm is middle-of-the-pack for thickness among the 655 42mm watches in the database.
The Approach J1 is 1mm wider, 1mm longer, 1.2mm thinner and 15g lighter than the Approach® S70 - 42 mm. 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.
Lay your arm flat on a table, palm facing up
Measure across the flat top of your wrist (not the circumference)
Measure at the point where you wear your watch — typically just below the wrist bone
Wrist width ≠ circumference. We need the flat width across the top of your wrist where the watch sits, not how far around.

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.
- 1. Lay your arm flat, palm up.
- 2. Measure the flat width across the top of your wrist — not the circumference.
- 3. Measure where you wear it, just below the wrist bone.
Leather: Attaches at the lugs, so the case back rests on your skin. Thins and softens with wear. The default: depth about seven tenths of the width. Typical figures, not this model’s own.
