Jomashop is completely legitimate. I have bought several Omegas from them and never had a problem. The watches are new and unworn. You will get everything that you would get from an Authorized Dealer (watch, box, booklets, etc. EXCEPT THE OMEGA MANUFACTURER/WARRANTY). So the risk is that IF you get a lemon, you have no Omega Manufacturer/Warranty. Now, that doesn't mean that Omega won't fix it if there is a problem. What it does mean is that you will have to pay for it. As I said, I've never had a problem with any of the Omega's watches from Jomaship, but it could happen. As for your question about the Grey discounts, it's simple. Luxury watches have a huge mark up from AD's. If AD's have watches that are not selling or not selling fast enough, they sell them for Grey's at a lower cost than you can get from the AD. Then the Grey still has enough off a mark up to sell to you and still have a profit. Think of it this way. An AD has high expenses given that it has to have a nice official store, employees, etc. For a Grey, it has a warehouse and sells the watches via email -- so the Grey buys excess watches from the AD at a lower price, they have lower expenses to sell from you, and that's why you get a discount.
