Probably because, as AP's own promo video shows, it is white, and not the grey which some sites appear to show. I would trust AP's own colour balance rather than 3rd party sites:Very nice job, but why not while at it, fix the white seconds @12 to the correct grey like on the gen LBJ? considering all the mods, making the correct grey is a very easy mod, and a big tell on the watch!!

If it was grey, it would be lost on the grey background of the dial.
