This topic has been beaten to death around here. Most members insist the "dots" are correct as this is the type you normally see when searching for pics of the gen. Some of the old time members who aren't really around anymore will tell you that back in the 70's, Patek made custom watches for the "special" customers. If you were willing to drop that kind of coin, you bloody well could get any dial you wanted. The rumor is there were gen PP's with the "grid" style dial. Personally I like the grid style better but I am bias because that is the style I have.
Edit: And regarding the seconds hand, the original jumbos didn't have it but did later on. It's a personal preference, I plan to have mines removed.
