In order to know what size watch strap that you need, you will need to grab a "mm" ruler and measure in between the "lug ends" of your watch.

Here is an example of what you need to measure:

What is the correct size watch strap for my wrist?

What is the proper watch strap width for my Panerai watch?

The general rule of thumb with Panerai watches is simple. If you own a 40mm case Panerai then you need a 22mm wide watch strap, for a 44mm case you would need a 24mm wide watch and for a 47mm case you would need a 26mm wide watch strap. Please refer to the charts below to find the correct lug width for your Panerai watch:
