Awed by the spectacle of the stars, Van Cleef & Arpels is reinventing the Lady Arpels Jour Nuit watch, introduced in 2008, with a new model 33-mm in diameter that required three years of development. The diamond-paved moon and stars perpetually pursue the sun, embellished with guilloché yellow gold. Featuring a 24-hour rotating disc, the dial revolves almost imperceptibly.

Thanks to the depth effect of the Murano aventurine glass, Lady Jour Nuit watch portrays the immensity of the cosmos and the magic of a starry night. A veritable feat of technical design, the aventurine glass presents delicate openwork to hold the diamond-set white-gold stars.The painted blue mother-of-pearl shroud symbolizes the horizon framing the poetry of space. It exhibites a guilloché effect. A sapphire crystal covers the rear of the case and the oscillating weight, adorned with a polished star-studded sky.

Decorated using the enamel decal technique, it reveals a protective fairy admiring the winsome ballet of the planets.
