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® S50 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® S50 is the slimmer of the two (11.4mm vs 12.6mm), so it slides under a cuff more easily.
On the wrist the Approach® S50 feels lighter (29g vs 44g, case only).
Among the 312 43mm watches we hold thickness for, the Approach® S50 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 656 42mm watches in the database.
The Approach® S50 is 1mm wider, 1mm longer, 1.2mm thinner and 15g lighter than the Approach® S70 - 42 mm. Both are circular.
