6263 - bargain or fake

[tudorfan]

I spotted this auction on the sale room for a 6263
I assumed it was a frankenwatch given the very low estimate on it and the auctioneers mention of the movement being modified.

It ultimately sold for £22000 plus hammer.

I'm not a Daytona expert but I'd be happy wearing that on my wrist.

So my question is was this a bargain or did someone get swept away bidding on a cobbled together watch
