Rolex becomes more worth then release price?

[Yzord]

My neighbor is a watch/clockmaker and i showed him my new Rolex. After inspection he gave it back and told me first that it was real but also that it becomes more worth in the future.

The reason is that he once bought a Rolex when he worked for a clockmaker and that that time piece became more worth then the retail price back then. Also the gold in it (his and my watch) should become more worth (of course thats a speculation) in the future.

What is your opinion about that? Will a Rolex become more worth in the far future then retail price?
