Real or Fake? LA Downtown Jewelry District

[talljune]

Hello,

I am a watch novice, and I am shopping for a new Datejust Mens Steel Rolex to give as a wedding gift.

I don't trust eBay and most of online retail shops. However, Rolex selection at Los Angeles downtown jewelry district (around Hills and 6th St) is very nice. The price is about 30% discounted from what the authorized dealers sell for. The shop keepers in downtown jewelry district swear by the authenticity, and emphasize that their shops will be out of business and shut down if they ever sell fake goods. It does come with a real looking box and papers.

Should I believe them or not?!
Let me know your thoughts. THANKS!
