I have been looking at used RM016 and am wondering why exactly are these the most inexpensive RM’s on the used market and why they don’t hold their value? By all accounts it looks like any other very nice RM so why is this particular reference so inexpensive second hand? Are there any issues with it that aren’t apparent I should know about? Is the RM016 considered an entry level RM? Is it the calatrava of the RM lineup? Greatly appreciate the input of the RM experts in here on this reference.
