Wrist fit
A quick size band — not a medical instrument. Measure where the watch will sit, then browse that case range.
How to measure
Wrap a soft tape (or a strip of paper) just above the wrist bone. Note millimetres. Most adults land between 155 and 195 mm.
Case size vs look
36–38 mm reads dressier; 40–42 mm is the modern sport default; 44 mm+ needs a larger wrist or a bold taste.
