I just bought my first rep and wasn't used to the whole idea of reps.One day, as I was roaming between meetings I stopped by a local Omega AD to have a look at some of the Omega offerings and, you know, to have some fun. Unfortunately I totally forgot about wearing my rep IWC Spitfire.
As I approached the counter I suddenly realized that I was wearing the watch, but what could I do? So while looking at some PO's I took the my watch off, and the shop owner instantly recognized it. She said "they just never make those IWC dials right, do they? but I love the job they've done on the case". I was a bit surprised, not because she bluntly called me out, but by her keen eye. I said "yeah, wish I could find a cheap dial to install" or something along the lines. "So you've got the bug too", she laughed and we went on talking about reps gens etc. Really cool lady and funny as hell.
As it appeared she was quite a watch expert and rep collector with over 80 watches in her watchbox (all men's watches, btw). A couple of weeks later I stopped by and she showed me part of her collection: from cheap datejusts to really high end 1:1's. It was like GTG at Christmas on steroids.
We are still in touch, but I learnt my lesson: never visit AD with a rep.
