so I can't answer your question.
But if you ask me, I think you're a bit too pessimistic. I agree the economy isn't in a good shape but I don't think we'll have a bearmarket till 2017. I'm more optimistic and I really think the worst is behind us. Will we have a booming economy the next 2 years ? Probably not but I do think times will get better. The next 1-2 years will be a period with ups and downs but I don't see a doubble dip recession. And from 2011-2012 I expect a good recovery. China and India is such a huge market with STILL a lot of potential
About the value of watches ... again I think we left the worst behind us. I don't think prices will drop by another 10 or 20%. On the other hand flippers who had it easy because every new Rolex (GMT II, green sub, Daytona, Deepsea) was easy to flip the first 6 months with a huge profit will be a thing of the past. The huge premiums on Nautilusses or some Panerai's and LE AP's are imo gone. A few off those will always sell with a premium but I hope nobody will be stupid enough to pay 50% over list ever again (and definitely not for a non limited watch). Besides, i think and hope that most of the collectible watches are in the pocession of enthusiasts/collectors and not secondhand dealers or flippers. And these collectors won't imo sell a watch because they think it could loose 10% of it's value.
If you think you should sell your watches today because you think you will get them back less expensive within a few months/years, go ahead. But I wouldn't bet on it ;-)
