Arnold & Son Perpetual Moon 38 Mintnight

Swiss luxury watch brand Arnold & Son presents Perpetual Moon 38 Mintnight, a new colourful interpretation of its iconic moonphase watch.

‘Mintnight’ showcases the night in shades of mint green, turquoise, teal and sky blue. A gentle graduation of coloured mother-of-pearl adorns this limited edition of 18 timepieces. The mother-of-pearl’s opalescent sheen is complemented by the shimmer of the ruthenium moon and dial foreground, together with the diamonds that sparkle on the bezel, horns and hour-markers of this poetic creation.

Measuring 38 mm in diameter and 10.44 mm thick, the case of the Perpetual Moon 38 Mintnight is fashioned from a block of white gold. Its bezel, four horns and crown host a total of 80 brilliant-cut diamonds. When added to the 22 diamonds adorning its buckle, they amount to a total weight of 2.57 carats.

Behind a wave of ruthenium crystals, a maze of blue, mint-green and turquoise hills emerge one after the other before receding towards the horizon. The sky above this scene, scattered with hand-painted stars, is filled with an immense moon. Its surface, also made from ruthenium crystals, illuminates the sky. Five marquise-cut diamonds indicating the hours provide the finishing touch on this work of art.

Visible through the sapphire case-back, the exclusive manually-wound A&S1612 calibre with a diameter of just 29.4 mm offers an autonomy of 90 hours.

The Perpetual Moon 38 Mintnight houses a large moon disc with its various crescents occupying the wide window situated between 10 and 2 o’clock. The extremely precise moon-phase mechanism of this watch needs a correction only after 122 years.
