Does Chrono24 charge a fee?

I'm curious to know, does Chrono24, the popular online marketplace for luxury watches, impose any fees on its users? I've heard that some platforms charge sellers for listing their items or taking a percentage of each sale. Does Chrono24 operate in a similar manner, or do they have a different fee structure in place? As a potential buyer or seller, I'd like to understand the costs associated with using their platform before making a decision.
