The 100 years isn't the issue here, nor Rolex in particular. Replace Rolex with a contemporary brand and dcolkitt's point stands even more clearly. There is nothing in the law that makes a distinction between a Rolex watch and some other brand that people may purchase hoping it will garner prestige someday through present-day marketing efforts. It would be absurd to make that distinction.

The salient point is many things may be purchased for "speculative profit you hope to make [...] reliant on the business", but that by itself doesn't make them securities according to the law, so it's just not the right test to use.
