You know, the watch you researched, stared at, found picture after picture, ordered it...then it arrives and it just doesn't ring the bell for you.
Or it could be your impulsive purchase. The one you knew little about, pulled the trigger on a whim, and it turned out a little research would have saved you from that purchase.
If you dare to share it, I think we'd all love to see how much you lost on the eventual resale of that underwhelming timepiece. Because, you know, we've all been there -- and to see others endure the same is always comforting! :)
