Johan, I think is lamenting that there is any price drop at all. Years ago Daytonas were grossly underpriced, and the supply particularly when they were relying on Zenith for El Primero movement to modify was far short of demand. Hence on an average day back in say 1995/1996 you could by a steel 16520 Daytona for say $3850 (before the the next price increase when it went to $4,350) and you could sell it the same day for $7,500-$8,000. You could even wear it for 4-5 years, get it serviced and sell it for nearly twice what you paid. Then as prices approached the $5,500 to $6,000 in the used market you could sell it for $8,500-9,000. When I got one of the early 116520s in 2001 for $6,000 I got an insurance appraisal from a gray market shop (since list price was not its accurate value), the owner of the shop had not seen one in person yet and told me they are selling for $12,000, and wrote the appraisal accordingly.
Once list priced got to $9,000-9,500 fewer people could afford them, they had been in production for several years and then with the economic slump of 2008/09 prices got soft on the secondary market and people couldn't flip them the same day for a profit. Still resale is quite good, you can't buy a Sub, GMT, Milgauss, Explorer etc and sell it the same or next day without experiencing some depreciation.
