Vintage is where it's at.
When you first touch down here you go for a 'quick fix' nice modern rep that's very gen like. Then you pick up maybe one or two more, then you start looking at the incredible vintage builds that go on around here...the adventure begins.
This is when you really begin to learn, start acquiring 'bits' start hunting the internet for that missing piece(s) learn the history of the watch and the subtle differences that change over time. Begin to acquire tools, start experimenting on ageing techniques, collect reference photo's, start sending PM's & e-mails to cross reference theories.
Sell your first watches to pay for a gen insert or similar begin emptying the wallet, start robbing banks...
And then before you know it (as has been said) you could have bought a couple of nice gen watches...but that's boring!
