One of the fears of buying straps online is that you might not know if the strap is of the correct length to suit your wrist. We hope that by the time you are done reading this page, you will know what size you should get. There are two methods that we will run through:

1. Method 1 – Measure your current strap
2. Method 2 – Not-So-Quick Math

Method 1 – Measure your current strap

This method is the quickest way to know what size to order, but it might not be very precise. What you will need is an existing two-piece strap on your watch. It does not have to be a leather strap.

1. Measure the length of the long and short piece of the strap. (Example: 105mm on the long strap, and 80mm on the short strap)
2. Choose the size with the following size chart – the closest to the total length of your existing straps. (The closest size in this example would be M (115mm + 70mm = 185mm)
3. Note that this is still an approximation, and you should adjust accordingly if your current strap does not fit your wrist perfectly.

Method 2 – Measure your wrist size

If your cannot measure your current strap for some reasons, you would need to measure your wrist size and purchase the strap size according to the guidelines below. If you are between sizes (for e.g. wrist size of 16.7cm), we recommend to size up.

Step 1: Measure your wirst with the rope:

Step 2:Measure the rope length with the ruler:

And then following the size chart below to know your strap length:
