Those 4 brands mentioned are 4 different brands that target 4 different consumers with different levels of purchasing powers.
Let’s look at the hierarchy of brands first.
Note: People disagree with this diagram especially with A Lange, Breguet and Jacquez Droz. I believe Richard Mille, an independent brand should have it’s own tier along with MB&F and Urwerk. This chart is made by the marketing department of one of the brands themselves. We can all disagree with the positioning but they’re the experts. 😉
Patek Philippe, Audemars Piguet and Vacheron Constantin are all on the Top Tier category …
