Please review the video below on how to measure your wrist for the perfect bracelet fit.


It's best if your Sailormade bracelet fits snugly. We suggest that you measure your wrist with a flat measuring tape. Wrap it tightly around your wrist to get your measurement then find the corresponding bracelet size on the chart below. This applies to any bracelet in our collection. Note: not all bracelets are offered in every size.
