IWC experts, please help...
I am in the process of acquiring a discontinued Portuguese Rattrpante RG IW371204. I have found one piece that is very close to be finalized, however upon closely looking again, I noticed that this particular watch's crown is not signed. No "fish" logo on the crown. BTW, this is a pre-2000 watch and comes with the original box and papers.
My question is, did IWC ever produced this watch with un-signed crown?
This will be a keeper for me so I would not be willing to purchase one in a non-original condition.
Thank you very much for reading and I hope someone in the know could share his knowledge...
