I've got a vague interest in high-end watches but i'm looking to extend my knowlege, and possibly looking into picking up a second hand piece in the future. When i say high end, i don't mean Animal/Seiko or even Armani/Gucci etc, I mean Panerai, Breitling, Patek Philipe, Tag Heuer, Rolex, etc. I feel i my be asking in the wrong place lol, but anyone have any info/experiences?
