I don't like to rain on anyone's parade.
If you like it, congratulations! Generally though, it's a better idea to ask before bidding/winning to see if others think there is some value there. It looks like this would be a SKP333, but to me it doesn't appear to be "brand new" due to what looks like wear on the bezel and strap. These are discontinued, and were (in my opinion) a fairly common offering someone would see at a mall or department store.
An online Seiko dealer ("Authorized Dealer = AD", meaning you'd have the Seiko factory warranty) sells a related model (SKP332) for $108 which is truly brand new, with tags and a full factory warranty.
That style isn't what I personally like, so to me I don't see value in it. But maybe there are others here that may think you did just fine.
edit: It's not a SKP333, as there is no date window. The design is similar enough that they are probably somehow "related".
