The watch market is not going to crash unless the economy bottoms in every way. The last two severe market events did not lower prices at all on vintage and luxury watches. There is no reason to think prices will be going down. There are no indicators to substantiate claims of that kind. The only thing that would cause a downturn would be the kind of generational change that cause other collectibles to drop in popularity, such as cars like Model Ts or Hopalong Cassidy toys. When that generation of children reached old age, they stopped buying, and later generations had no interest, but Speedmasters have proven they have an appeal that goes beyond one or two generations. There are thousands of 20, 30, 40 yr old collectors entering the market, and this may be true for many other vintage watches. Prices will hold or move upward for nice old watches. There will be no crash in prices.
