I think there's misinformation
I personally don't understand how Chrono24 works even though I've tried to sell but didn't, and bought 2 watches over there
First of all, there isn't always Escrow, on both my transactions, I've either Paypal'ed the seller directly, or was given a bank account and expected to send money to bank account, the reason for the spammy "Did you buy this watch?" emails is because they expect the seller to pay them, instead of taking a cut directly
But to answer the question, to sell, yes it's better than most I guess
But my own TL;DR: Their security to me is just smoke and mirrors and I haven't actually read anything about how they can or do protect sellers or buyers, I assume they just don't
What happens when a seller does a chargeback?
What happens when you pay but the seller runs? Do they pay your loss from their own pockets?
