Audemars Piguet Royal Oak 31mm

It's a Royal Oak! For ten thousand less than pretty much any other vintage no matter how old or beat up. It's small yes, but one of the hottest Royal Oaks right now is that mini (going for ~100k) so that logic doesn't hold much water. Can't imagine this stays around for long. If you know you want one but are anticipating a years long wait to afford it, go off and treat yourself.
