[Pro Tempore]

Hi New to Forum - i am looking to start a collection of rolex's ( slowly) , but as far as investment buys go, what models should i be looking at? investment as in 5 -10 years from now, not to wear ( have and wear 2005 GMT 2 ) so hopefully buy with my head not heart.
The ones i like are modern and functional, the ones that currently fetch big dollars seem to have lost thier hands , look like they have been buried in the bottom of the garden since before man set foot on the moon ( but as long as they have red wording on the dial...........)
