This watch features a highly surprising “face”. The watchmaker has opted to open three windows in the fluted case of pink gold. The jumping hour appears in a window at 12 o’clock, while the date is visible in a window at 6 o’clock. The minutes are read off the central dial by the blue, arrow-shaped hand, which constitutes the symbol of this brand. This original presentation of the time called for the development of a particularly ingenious mechanism. The automatic movement is visible through the sapphire back.
