On this page we explain how to determine the length and width of the strap to perfectly fit your watch and wrist.
1 - How to determine the strap width
moreless
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
75mm

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.
