About the same amount as it would have been unworn, perhaps a 5% increase, in 25 years you may be looking at a 35% increase due to its limited status...
If you look at page 4 on this site Lot 398 http://www.artcurial.com/pdf/presse/2007/r1261.pdf I sold a series of these watches that came in a group of 6... I think that they were about 20k each and this one sold for 50k euros... Not a bad return in 17 years!! If he had have sold all 6 he would have made alot more money...
Big Phil, nice collection mate
Makes an interesting comparison with what a £100k car would be worth after the same period of time...
Depends if that £100k car was a Ferrari F40.....! I 'looked' at one a few years ago when I was on my way down to the south coast, in a small specialist dealer, and it was up for £125k. The last one I saw a few months ago the guy had paid £250k for!!
Classic car market is very fragile, especially in uncertain economic times. Anyway, the comparison was with a new car.
