Case diameter can make or break how a watch wears. Here's how to measure your wrist and pick a size that actually fits.
A watch that's the wrong size will never feel right, no matter how good it looks in photos. Here's how to get it right.
Measure Your Wrist
Wrap a soft measuring tape (or a strip of paper) snugly around your wrist, just past the wrist bone. Note the circumference in centimeters or inches.
Match to Case Diameter
As a general rule: wrists under 16cm suit 32-36mm cases, 16-18cm suit 36-40mm, and 18cm+ comfortably carry 40-46mm cases. Check our full size guide for the complete chart.
Consider Lug-to-Lug Length
Case diameter isn't the whole story — lug-to-lug length determines how far the case extends over your wrist. A 42mm case with short lugs can wear smaller than a 40mm case with long ones.
When in Doubt, Try It On
Photos and measurements get you close, but nothing beats trying a watch on. If you're between sizes, our support team is happy to help you decide.
