Are you really in need of a watch at the moment? Why not just save up for the Reverso? My local Torneau had 4 Reversos in the used section last time I was there. I'm sure you can snag one for under 4k.
For me (just over a year out of college), the difference between $1400 and $2200 isn't so bad (I can snag the IWC for $2K new w/o any discount from retail plus the gift card). The difference, however, between $2.5K and $4k is quite substantial, and while I could probably swing a Reverso when bonus time rolls around, I'm trying to stay level headed financially. Gotta keep the priorities in check. A Reverso is on my list of things to get, the one I have my eye on is more in the $6-7K range. In due time.
I like the IWC not because it's an IWC, but rather I have a need for an elegant yet simple round faced watch that is very versatile and will last me for years and years. I've looked at Omega, Longines, JLC, Cartier, but the IWC provides just what I'm looking for. In the long term I also would love an Omega Seamaster Automatic to cover the weekend and casual watch needs.
