Nature is a favourite theme of Van Cleef & Arpels. Now, for the Lady Arpels Heures Florales timepiece, the storied jeweller has drawn inspiration from Linnaeus’ Floral Clock, which tells time by observing what hour of the day different plant species open and close their flowers. Using 166 moving elements, the watch’s flower-opening module displays the hours and minutes: 12 flowers with enamelled petals surrounding diamond centres blossom every 60 seconds. The white mother-of-pearl dial is also embellished with sapphires, enamelled butterflies, and gold branches. With a self-winding mechanical movement, the watch is poetry in motion housed in a 38-millimetre white or rose gold case.
