I think they're going to stay on top for a long time. Good marketing, good product, good everything. Sure, some references won't be hot, some are duds, a lot of women's models sell slowly (not to mention it seems the new women's model isn't garnering universal love). Patek Philippe also attracts some of the biggest talents! As you already know. Booking those talents fully so they don't have time to work for other competing brands. Very few brands, but the biggest and best brands can do this...
