Approach J1 vs Approach® S50
Size, specs & wrist fit compared

Which one fits you
Both need much the same wrist — roughly 45–61mm 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 and Approach® S50 share a near-identical 43mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Approach J1 is thinner than 87% of the 318 43mm watches we hold thickness for, the Approach® S50 than 87% — so both wear flatter than their widths suggest.

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.

Case 43.0mm · Lug-to-lug 43.0mm · Thickness 11.4mm · 29g
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.
