Van Cleef & Arpels has never approached watchmaking in a typical way, preferring to use technique in order to tell a story, as already shown with its Pont des Amoureux watch. This year's Ronde des Papillons is no exception. Several technical specificities distinguish this watch: retrograde hours are shown by a swallow while minutes are indicated by a trio of butterflies which appear in turn and move at different speeds. At the push of a button, they flutter around the dial not in one hour but in ten seconds before resuming their usual flight at exactly the right time, as the mechanical movement catches up the ten seconds of the butterflies' dance. For this timepiece, Van Cleef & Arpels has used the decorative arts of miniature painting, engraving, and crafting of mother-of-pearl.
