Should I get the 34mm or 38mm Watch Series 5?
The Watch Series 5 comes in 2 case sizes — 34mm, 38mm. Which one suits you depends on the flat width of your wrist rather than preference: the larger sizes need a wider wrist to sit inside the edge. Set your measurement in the size picker above and each variant reports its clearance in millimetres.
