They didn't release official figures on this 5089 as far as I know, but it's almost certainly a number between 3 and 10. (10 was the official number for each of the 5089 dials they made for the NYC exhibition, and it was considered quite high!)
So in Gordon's first picture you can find anywhere between 20 and 66% of all Rousseau Lions that Patek ever produced, which is not bad!!
