Size chart for bracelets
To determine your strap/bracelet length, you can either measure your wrist circumference and determine your bracelet length in the table or use our templates, which you can download below.
Please find our templates for download here:
Instructions: Print out the document and make sure that no page scaling is preset. Cut out the template along the red dotted line. Place the watch on your wrist and pull the strap through the cut slit. Make sure that the template is not too tight on your wrist and that you have a little space between your fingers.
Please note that leather underbands result in a longer strap length.
