Newbie questions

[jctrolex]

I've been eyeing an AP15400 for a little while and thinking of adding it to my collection. The workmanship on the case, bracelet and the movement is absolutely stunning. My question is are they fairly robust watches and can handle daily wear say like a Rolex Datejust or an Omega Aqua Terra? Or do you have to treat it with kid gloves and only wear it on special occasions like a fine dress watch? What is the recommended service intervals for them and how much does a regular service cost? Are they serviced in North America and what is the usual turn around time? Do they retain their value well? Do you save much by buying used?
Thanks in advance.
