Apple Watches Under 40mm
71 Apple models in the 0–40mm range, actually measuring 33.3mm to 39mm. Compact sizing that suits smaller wrists and dressier looks.
Thickness barely moves across the group — 9.7mm to 11.4mm — so these wear much alike under a cuff.
Releases run from 2016 to 2025, so this mixes current models with older references.
Which of these fits your wrist?
Roughly a 14.7cm wrist circumference — the measurement a tape gives you. Compared against lug-to-lug where we have it, case width otherwise.
71 of 71 models sit on this wrist without the lugs hanging over the edge.
Same size, other brands
The middle of this group sits around 36mm. These are the closest matches we hold from other brands — useful when the size is right but the Apple isn't.
