might have an explanation...
... as i was hunting for one. It was not easy to find a double sealed one. Plus most of the dealers you can find on the internet, do not have the watch, they will look for it once they have a buyer. I struggled a lot between those that claimed the watch was new while it wasn't, or was re-sealed, etc...
Maybe that one had a big premium because a mad guy wanted to safely have a sealed one minus the hassle, and is ready to pay for that.
The other 5070 went at the market price more or less...
Question would be, why do people pay such prices at auction house. You can find nice things at a decent price... And hard to find things as well, but you will pay big money for it.
