Measuring with a Tape

  1. 1 Wrap a flexible measuring tape around your wrist, just below the wrist bone where you'd wear a watch.
  2. 2 Make sure the tape is snug but not tight. You should be able to fit a finger underneath.
  3. 3 Note where the tape meets itself. This is your wrist circumference.
  4. 4 Enter your measurement below to get your recommended watch size.

Additional Tips

When to Measure

Measure in the evening when your wrist is slightly larger. This ensures a comfortable fit throughout the day.

Temperature Matters

Wrists expand in warm weather and contract in cold. If you live in varying climates, measure at room temperature.

Activity Level

For active use (sports, outdoor activities), consider a slightly looser fit. For dress occasions, a snugger fit looks more elegant.

Personal Preference

Ultimately, choose what feels right. Some prefer the bold look of a larger case, others the subtlety of a smaller one.
