It would look vastly different. The location of the day/month date window relative to the lines is completely off in the rep, which makes the “PATEK PHILIPPE” look like it is placed too high. Immediate tell right on the center of the dial. For the 5711 a gen Dial is not worth it as the PPF dial is as good as it gets. On the 5726, the dial has many flaws and a gen Dial is absolutely worth it.
Looks to me like the day/month window is just in a different position, not just "relative to the lines". If so your day/month wheels won't be aligned with the windows on the gen
The rep also has the datewheel that is too sunken, which they're trying to dissimulate by adding a cyclop. I suspect it would look weird with your gen dial, if it aligns at all
Try doing a collage with Photoshop of the rep dial over/next to the gen one to see whether the windows align, if not then you can forget it
