Size, specs & wrist fit compared

Which one fits you
Both need much the same wrist — roughly 49–66mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.
The Watch 3 and Watch 4 share a near-identical 46.2mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Watch 4 is the slimmer of the two (10.9mm vs 12.2mm), so it slides under a cuff more easily.
On the wrist the Watch 4 feels lighter (48g vs 54g, case only).
The Watch 3 is middle-of-the-pack for thickness among the 155 46mm watches in the database.
Among the 155 46mm watches we hold thickness for, the Watch 4 is thinner than 86%, so it wears flatter than its width suggests.
The Watch 3 is 1.3mm thicker and 6g heavier than the Watch 4. Both are circular.
