Vacheron Constantin Ref. 30051, Skeletonized Tourbillon

I have my Vacheron Constantin Ref. 30051 skeleton tourbillion, recently returned from service, and now for sale or trade. I was going to keep it, but recently I started looking at the Lange Datograph perpetual, and there's no point keeping two manual wind watches. If you have a Datograph Perpetual *EDIT: or a nice Blancpain Milspec 1* and would like to swap, or if you think you want to purchase this watch, let me know. We can meet face to face and get the transaction done quickly. This is watch number 2, literally back from service for 2 weeks, with the original inner and outer box and papers. It's pictured with my cartier deployment, but comes with the original VC buckle as well.
