Rolex daydate platinum arabic dial.

Hello everyone i recently decided to buy the platinum rolex daydate arabic dial. Im from aus. As most of you know this isnt a cheap watch and i am doing it to avoid the depreciation of my fiat since most of it is held in USD and Its projected to decline in its avlue against the aud . Blah blah financial talk. I was wondering if this watch would be easy to liquidate if the time comes and what is the market like for this type of watch.(My comma is broken). will it hold its value and such . i couldnt care less about profits.
