This Poetic Complication piece by Van Cleef & Arpels, Lady Arpels Jour Nuit Oiseaux de Paradis, has a mechanical automatic movement that has a 24-hour module specially developed for Van Cleef & Arpels, driving the dial that features a bird-of-paradise flower and a moon in diamond. The dial rotates once every 24 hours, slowly changing the appearance of the piece and suggesting the transition from day to night. The top, fixed scene has a blue bird of paradise.

The watch has a 38-mm case, with diamond-set bezel, a navy blue alligator strap mounted on the central lug characteristic of Lady Arpels watches, and a white gold pin buckle also set with diamonds.

This is a numbered, but not limited, edition. Price on request from boutiques.
