§ Size Guide

Find Your Fit

Measure your wrist and we'll recommend the right case diameter, strap length, and strap width — so your timepiece sits perfectly the moment it arrives.

How to Measure

  1. Wrap a flexible tape or paper strip snugly around your wrist bone.
  2. Keep it flat, not tight. Note the circumference.
  3. If using paper, mark the overlap and measure against a ruler.
