+1, my favorite too...
Vacheron Constantin, in my opinion, has the richest history when it comes to skeletonized movements. This would be a fitting piece. I've heard a similar watch in rose gold, and although it wasn't very loud, it had excellent tonal qualities and speed.
A second choice? A Patrimony tourbillon, perpetual calendar, minute repeater in platinum would be another practical piece that I could envision becoming a daily wearer... And this piece has a beautiful rich sound from the minute repeater; among the best that I've heard.
