Azure, navy, ink, midnight
Perpetual Moon 38 Night Tide is sculpted from a block of white gold. Once shaped, the 38 mm diameter and 10.44 mm thick case is adorned with 80 high-clarity diamonds. Together with the brilliant-cut diamonds adorning the buckle and the marquise-cut stones on the dial, they give a total weight of 2.62 carats. This gem-setting announces the ornamental richness with which Arnold & Son has composed this women’s complication.
Wave after wave, trough after trough, shades of blue and grey follow one another, creating a jumble of undulating seas, mother-of-pearl and ruthenium. Above this scene, a starry sky, punctuated by luminescent hand-painted constellations, is filled with an immense moon. Its surface, also made of ruthenium crystals, lights up the sky. This exceptional material has become a signature of Arnold & Son, adding preciousness, light and texture to its creations.
The grande dame of mechanisms
This limited edition of 18 pieces brings the watchmaking excellence of Arnold & Son to women. The Swiss brand has dedicated the smallest movement in its collection to Perpetual Moon 38.
At 29.4 mm, the A&S1612 calibre has been sized to fit the case. The hand-wound movement continues the house’s tradition of calibres with long power reserves, reaching 90 hours.
Her Majesty the Moon
The star complication of the A&S1612 calibre is its moon phase. True to Arnold & Son’s astronomical principle, Perpetual Moon 38 Night Tide features a moon disc almost as large as the calibre itself. The successive shapes of its crescent occupy the large aperture between 10 and 2 o’clock, while the form of its cut-out faithfully recreates the appearance of the moon.
In keeping with its tradition, Arnold & Son has given this moon phase an accuracy of 122 years. Continuously rising, it will take more than a century for this moon to lag one day behind the real one in our skies, watching over the oceans.
