Generally speaking watches don't stack up especially well as investments. As with any investment people will regale you with tales about how well they did with a particular watch but will be silent about the watches which did not do so well. As with any market you can be lucky and I'd say overall the vintage watch market is on an up at the moment. Generally the brands which do best are not the ones which are already well traded such as JLC but the lesser known brands where someone has done some research and then marketed it around the watch forums. But the current up is largely because of fashion and could just as easily nose dive again.
Watches are money for some people. They will buy high end watches such as pateks, and shrink wrap them and keep them in a deposit box
