I could see that amongst hardcore WIS's, and possibly some hipster >30 year olds. The hipster's will probably just download the Breitling iPhone application though.
I think, downturn continuing, the trend will be more towards the Movado, Rado, Hamilton, Tissot's etc. for the population at large who actually care enough to buy a ~nice~ watch.
Only downside to going vintage for econimic reasons is-- how much more will you need to spend to get the old movements serviced on top of the selling price. My AD is getting $500-600 to service a 1570.
Interesting to think about though.
