I have been looking at the 6263 for a couple of months (due to the pictures of freddy333's 6263).
In the pictures the watch looks a little chubby. And even more so in the dealers photos. A gen, or freddy333's, look thinner and more elegant. It may be due to the look of the plastic bezel, this version has a rounded edge . I guess that the large size Rol*x on the dial ad to the chubby look also.
Still, most people want a good looking out of the box watch and you have to live with the flaws.
