Interesting original question, yes.
I'm with Abel here, agree absolutely.
And like to add:
The more I check Ebay, the less I like it !! (So, I look less and less.)
For obvious reasons... as for example ending auctions early. I hate this style!

: Interesting view. I must confess I do not have very much experience
: in the Rolex field. But I do make a bid sometimes on Zenith,
: Seiko, Jaeger,...may be a few other brands as well...

: I tend to agree with your experience/view. The only thing I could
: think about is that a lot of people are "frustrated"
: by auctions that are ended prior to planned end of auction. By
: making a strong bid early in the auction it could prevent the
: seller form ending the auction early...maybe??

: Just my thought/explanation...

: Best,
