In Asia, or with the right retailers, who know of who is able to write cheques of $300,000 for a platinum Antiqua...used...and 99% con...it is absolutely no problem.
Trouble is, these dealers keep their list of customers VERY secret.
In say the same place, Asia, a priced painting by say Joan Miro..and if not well known piece, may fetch 30% of what it will fetch in southern Europe.
A Vacheron may fetch 1/3 of the price if one cannot locate the right buyer...this is how I made my money too...because I made only 2 trades, only 2...in 2009. And I learned a little....but unfortunately, I have nothing left that I wish to sell.
Speaking of a top end brand, the labile market in Northern China...one can rip a hole in the resales of the top 3. But fill it with Richard Mille.
Luxury and art are very culturally linked. I would have and did buy quite a few good pieces of ahci in southern europe...where they have not a hot following.
Also, there is a dynamic game of balancing resale prices within the secondary market when they need to dump stocks, dead stock, into the world markets.
Antiqua is a prime example of how a product can be manipulated, because it is not "carefully groomed" by subtle resale tactics....employed by companies with a budget to do it.
