Juliet polished fire iridium - Legit check and price recommendations

[Mamsou]

Hello guys,

I am a complete Oakley beginner and looking for recommandations about these Juliet price and authenticity.
Serial # is O4-147 5521

Seller is asking 550€ without a box or coin which I believe make them a bit overpriced? Also I'm in EU and might be completely off but noticed prices are higher here.

Pics are not the best so I apologize in advance.

Thanks for your help!
