Obviously there must be a good reason for this unusual choice — if Patek ever decides to, they could open as many ADs as they please. As you were saying earlier, perhaps historically France has been more focused on other brands? Somehow, numbers must indicate that the Paris Salon is enough (though again, this wouldn’t entirely explain at the very least the rich areas in the South)...I frankly never looked into this, but it might be interesting to find out!😉
