Why no standard band fits this one

On the Royal Oak OffShore 25770 Chronograph Yellow the bracelet is drawn as part of the case: the first link continues the case profile instead of sitting in a gap between two lugs. There is no lug width to match, so there is no size to order, and a band bought by millimetres will not go in whatever the number.

It is not a rare way to build a watch. 1,083 Audemars Piguet references in the database are built this way, and across every brand it is 6.1% of the catalogue. What replaces the bracelet is a band cut to this case, shaped to close the opening the way the bracelet did.
