Sourcing a spare crystal and Original crown for Ref 166.010

Hello

Has anyone got a replacement acrylic crystal from these guys before? And is it the original crystal or a generic one without the omega logo?

Or is there anywhere else I can look besides often.com?

Also anyone know where to get an original 166.010 crown if possible?
