you to post 1 specific post for each one of your stolen watches, with ref in the title and a photo (just indicating your are always owner of all papers and boxes)
On IWC, Panerai, JLC and VC fora.
and also add the police declaration with date (paper?)
So no one could say just after a simple view to the internet that he could not be aware of the status of your watches.
I understand it is painful but all here could be more efficacious for tracking your other watches.
Best regards,
