Chopard LUC 150 All In One

I'm getting ready to send this watch to auction, but I figured I'd take a shot here and see if I could get something interesting.

I'm looking to sell or trade my Chopard LUC 150 "All in One" in White Gold.  This is a perpetual calendar, tourbillon, with equation of time and astronomical moonphase on the back.  Limited in production to only 15 in white gold, 15 in pink, and two or three one off pieces.  The only one of these LUC150s to ever go to auction went in May of last year at Sotheby's in Geneva, and was in pink gold.

Happy to meet in the DC/NY area.  The watch comes with a like new strap, all papers and boxes.  I'm looking for a Patek 5101 for exchange, but if you have a proposal with an interesting Lange, let me know.
