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 42mm (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 42mm 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 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.

Balanced Fit

10:09TUE 12lug to lug 43.0mmyour wrist 55.0mm

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.

How to Measure

Measure where you wear it, just below the wrist bone. Either of these works — the tool converts between them.

  1. 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. 2. Around — a tape, or a strip of paper marked and held against a ruler, snug the whole way round.
