I want a prestige watch.
I haven't decided which one, but it will likely be an Omega Deville or a Rolex AirKing. Those are two weird choices, but of the two brands those are the two models that I like best.
If I can find a suitable specimen, I would definitely buy used, but I need to bone up on the nuances of buying used watches.
I've never bought a used gun, even though I feel comfortable with guns and I think I know a serviceable weapon when I see one, but because the stakes are high, I prefer to buy new.
I feel almost the same way about a watch, but at least I know with a watch, it will never blow up in my face or fail to function with fatal consequences.
A reputable dealer and some kind of warranty would be a necessity.
