Model overview
Revealing the intricacies of the calendar function, the fully skeletonized Big Date complication of the Flying Tourbillon Grande Date B 1.618 movement displays the date in a format that is both easy to read and aesthetically minimalist. A simple colour accent on the aperture identifies the current date, without detracting from the mechanical subtlety of the two discs that rotate in time with the days. Bianchet adapted the big date complication, invented by Lange & Sohne in 1994, in a contemporary and essential style, revealing its mechanical ingenuity.
