Strap Length Calculator

Lug-to-lug is the total watch length from top lug tip to bottom lug tip.
Choose the range that includes your wrist circumference (cm). Options match the sizing matrix for your watch.

What determines strap length?

Strap length is primarily determined by your wrist size. Watch lug-to-lug and wrist shape can affect how the strap sits, but they do not change the standard strap length recommendation.

Between sizes?

If your wrist size falls between two ranges, we generally recommend sizing up for better comfort.

When should I consider custom length?

  • Your wrist is outside the Small–Large range
  • You prefer very short or very long tail length
  • You're pairing the strap with a deployant clasp
  • You want a specific hole position or tail length

Example

A 16.8 cm wrist typically fits a Medium (115/70) strap. If you prefer a shorter tail, Small may also work — but Medium is the safer choice.
