The Royal Oak's argument has always been geometry: an octagonal bezel held by eight exposed hexagonal screws, a bracelet that grows out of the case rather than attaching to it, and a dial worked in guilloché fine enough to read as texture rather than pattern. This reference states it at 34mm in steel — the mid-size register of the line — with a silver-toned Grande Tapisserie dial and white gold hour-markers. What matters on examination: the case geometry, because the alternating polished and satin surfaces are the first thing a careless polish destroys and the hardest to put back; the bracelet, because stretch in an integrated bracelet is neither cheap nor simple to correct; and the condition of the bezel screws and their alignment.
