Is the Huawei Watch GT 3 - 45mm thick for a 46mm watch?

The Watch GT 3 comes in 2 case sizes — 42.3mm, 45.9mm. 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.
