IWC caliber 89 crown yellow gold

[jjen]

Hello,

I have an IWC caliber 89 watch with a service crown. I am interested in getting the original crown with the fish logo. Looking for one in yellow gold.

Thank you!

What is the required diameter?
Whats the dimension of the thread?

I thought that most IWC cal. 89 watches were dress watches that were not waterproof. Non-waterproof crowns would not have a fish logo.

Can you post a picture of what you have?
