5mm is an ultra thin. You have been consistently wrong on this point. The very thinnest watches (which are also in the 5 figure range) are in the 3mm-4mm range. The Piaget Altiplano is 4mm in diameter and 3mm thick and is the thinnest watch in the world with mechanical movement and lists for $33,000. The Jules Audemar Extra Thin is 6mm thick. What he quotes is correct.
