My favorite is FPJ Calendrier; a very elegant and practical piece, especially in Ruthenium; recently had it fully serviced and is now good as new! love the Langematik anniversary, which interestingly was bought from a good friend in Europe soon after it came out because he didn't like the red XII (who does not like the red XII ;-)). It was also my first Lange piece; I believe it was 2002, if memory doesn't fail me
