Strap Size Guide

Here we explain how you can easily determine the length and width of the strap that perfectly fits your watch and wrist.

1 - How to determine the strap width

more less

The width of a watch strap is expressed in two numbers (for example: 20/18). This is the number of millimetres in-between the lugs of a watchcase on the one hand, and on the other hand to the number of millimetres where the buckle is fixed to the strap.

Example of the strap width: 20/18

20 - Width of the strap at the case, in-between the lugs

18 - Width of the strap at the buckle end

In that case, simply measure the length of the long part and the short part of the strap in mm. When you measure the short part of the strap, please do not include the buckle.


In other words, the strap length refers to the length in millimetre of the two parts of a watch strap:

  • - the long part with holes and pointed side
  • - the short part that carries the buckle

Example of the length: 115/75 (Medium)

115mm for the long part - pointed side with holes

75mm for the short part – buckle side

115mm

In that case, you can also easily determine the strap length that will suit your wrist by measuring your wrist size.

To measure your wrist size, simply use a soft measuring tape. If you don’t have one, we recommend you the following trick: take your wrist size with a thread, lay it down and then measure it with a measuring tape.

Finally, this table will help you find your corresponding strap length:
