While I'm not knocking other brands (I collect those too, but not in excess like IWCs), it is reasonably easy to get your arms around the history, the vintage pieces and the contemporary issues from our favorite brand. The amazing hardback Catalogue that is published every year is a great starting place. I'm not saying you could do it in a month or a year (As Alan said, I learn something new every week!). I'm sure in IWC's communication department there is a decent powerpoint presentation together encompassing the breadth/mission/history and offerings of IWC. Maybe it can offered up to the members of this Forum.
I couldn't imagine doing the whole history/mission/vintage and contemporary offerings for Rolex, AP, Vacheron, or Patek, or even worse, Panerai. The only other one that might be easier is Lange. Of course, I'm talking haute horology brands here.
The nice thing for you Jeronimo, is the "family" here is willing to help you with any question you have. We were all newbs once. I applaud you for jumping in and posting and also for your patience as you wait for your VC AT. Patience is not a quality I've discovered in many collectors. For most us, "yesterday" is not soon enough, when you have a watch on the way.
I can only imagine the joy that will encompass you when your AT arrives. I can't wait to see your post! Your enthusiasm will probably cause Shing to bust his "this year's budget"(again)! LOL!
Welcome my friend!
