There are great deals to be had as a buyer and sometimes fortune favours the brave as a seller.
I have been actively following and participating in auctions (in person and virtually) for 15-16 years and pretty much every auction has a “steal” of a price.
And in the last few years with the proliferation of auctions both online and in person there is just so much more supply.
You also need to understand which platforms attract the premium prices, which geographic locations tend to perform better or worse for some brands (even among the biggest auction houses, there are differences across their flagship auctions in each location) and you need to see the watches in person or have someone see them for you.
