F.P. Journe

There is something very special and unique about the Calendrier. In just a few days the day hand will snap back and reset to 1. Just awesome!...  

Brad, I have a few questions about the Calendrier. Perhaps "Newbie", but I'd appreciate your thoughts I notice that the date jump hand moves forward about 15 minutes prior to the hr. I love this piece, but technically speaking, how does the mechanism work...
