Here is some information on the PW from the Date Your IWC app. Hope this is helpful.

Ideally you contact IWC directly.

There is a video on www.iwc.com/at/en/journal/how-to-customer-care-faq.html " HOW TO REQUEST A CERTIFICATE OF AUTHENTICITY "
Or directly here: youtu.be/yKdqdYvbUQ0?si=hwFv53V7Vf8IVH-o&t=77
