There are many Rolex clone design with a commerce movement.
But a real Rolex is mutch better investment (regardless of #bitcoin). The Rolex price is steeply sloping and it is liquid, you always able to instantly sell or buy a Rolex

I agree that Rolex is fairly liquid. I have owned some watches that I spent thousands on and when I wanted to part ways with them you come to find out how illiquid some of the brands are. When it comes to the Rolex, I believe a submariner will be my first Rolex.
