Awed by the spectacle of the stars, Van Cleef & Arpels is reinventing the Lady Arpels Jour Nuit watch, with two new models. The diamond-paved moon and stars perpetually pursue the sun, embellished with snow-set yellow sapphires, or alternatively guilloché yellow gold. Featuring a 24-hour rotating disc, the dial revolves almost imperceptibly. Thanks to the depth effect of the Murano aventurine glass, these pieces portray the immensity of the cosmos and the magic of a starry night.
