Hi OF
My name is Park. I am a little bit curious about verification on the authenticity of IWC certification. So I saw some paper that say “Extract from the Achieves” and some say “IWC certificate.” I don’t know the different between these two terms.
Ps i tried to find the pictures for examples but couldn’t find it

Thank you
Park.

 

You also have the «stammbuch« to add in he mix.
