Need help and guide from the expert about my DUPONT Lighter LIGNE 2 authenticity....

Hello,

I am newbie as the dupont owner. I got this lighter when I celebrate wedding anniversary. I tried to sell in the local forum here ( in Indonesia ), but some people says it's fake.
Sorry, my english wasn't so good, so straight to the picture :
