I don't think there are any as you inquired "Perceived barriers against the Millenary QJ." I just think there is a stronger public interest in the ROO/RO. Its very rare to see a Millenary in the wild. In all the years its been on the market, I think only on one occasion have I seen someone wearing a Millenary in public (it was a white dial chronograph on a bracelet). A very interesting piece, but my favorite has long been the Star Wheel version.
Glad to hear that you buy watches you like and are not interested in them just because of a celebrity endorsement. I would never buy something just because a celebrity is endorsing it. Personally, I find it more interesting when I see old photos showing celebrities in the 1950, 1960s etc, wearing fine watches. That was back at a time when the celebrity bought the watch because they liked it, or it was given to them by a friend, significant other, or spouse. It was a personal choice to wear it back then. Now I find it far less interesting to see celebrity endorsed watches as its part of a promotional business deal, that the celebrity benefits from more than it is a personal choice to wear something they like.
